Short Answer Type Questions

Question 1.
Describe the size and extent of India.
Answer:
India has an East-West length of 2933 km. while North-South length is 3214 km. The total area of India is 32,87,263 sq. km. Its size is so long as to include 24 countries of western Europe. It covers 2.2% area of the world. It has a coastline of 7516 km. and land frontiers of 15,200 km.

Question 2.
Reason out why the North-South extent of India is larger than its East- West extent even though the country’s latitudinal and longitudinal extent (in degrees) is of the same value (30°).
Answer:
The East-West extent of India is 2933 kilometres, but the North-South extent is 3214 kilometres. Thus, North-South extent is longer than East-West extent by 281 kms. The fact is that the latitudinal extent (29°02′) and the longitudinal extent (29°18′) of the country are almost of the same value. This is due to the spherical shape of the earth. The equator is the longest circle on the earth (one degree of longitude measures 111 km.). But the length of other parallels goes on decreasing from the equator towards the poles due to the curvature of the earth. At 25° latitude, the length of one degree of longitude is 100 kms. Therefore, the East-West extent is shorter than North-South extent in kilometres. The East-West extent for 30° will be reduced by 30 x 10 kms = 300 kms approximately.

Question 3.
What is the longitudinal extent of India? What are its implications?
Answer:
India extend between 68°7′ E to 97° 25′ E longitudes. The East-West extent is 2933 km. which is roughly l/12th of the circumference of the earth. Thus, India has a longitudinal extent of about 30° longitudes. There is a time lag of 2 hours between the sunrise in the easternmost and the westernmost horizons of India. It means that the sun takes two hours to rise in Saurashtra after it has ri§pn in Arunachal Pradesh. There is a difference of 4 minutes for 1° of longitude. Therefore, there is difference of time of 2 hours (30° × 4 = 120 minutes = 2 hours). It has been suggested to have two standard meridians (instead of one) to reduce time lag to 1 hour.

Question 4.
‘India is a vast country’. Support the fact with three examples.
Answer:
India is a vast country. It is the seventh-largest country of the world. It has a latitudinal and longitudinal extent of about 30°. Its area accounts 2.4 percent of the total geographical area of the world. India has a central location in the Indian ocean.

Question 5.
South of which latitude, tapering of mainland begins? What are its effects?
Answer:
The mainland of India begins to taper South of 22° N latitude. This tapering divides India into two parts—Northern plains and Southern peninsula. It divides Indian Ocean into three sections—Arabian Sea, Indian Ocean and Bay of Bengal.

Question 6.
What is the effect of latitudinal extent on length of day in different parts of the country?
Answer:
India has a latitudinal extent of 30° almost 1/12 of the circumference of the earth. It affects the altitude of sun and inclination of sun’s rays. The differnce between length of day and night is about 6 hours in Kashmir. But the days and nights are almost equal in Kerala.

Question 7.
‘India’s relations through the land routes are much older than her maritime contacts.’ Discuss.
Answer:
India has a central location in Asia due to her Trans-Indian ocean routes and land routes in the west. The various passes across the mountains in the North have provided passages to ancient travellers. But the oceans restricted such contacts. The land routes helped to make contacts with West Asia.

Question 8.
Name the five countries whose frontiers meet at the northern apex of India.
Answer:
On the northern side of India, the boundaries of the following five countries meet together: China, Russia, Tajakistan, Afghanistan and Pakistan. These five countries meet at the apex of the north Indian triangle.

II. Answer each of the following questions in short:

(A) Natural Vegetation

Question 1.
Why has foreign vegetation beconae a problem for us? Elaborate with examples.
Answer:
Nearly 40% of plant species found in India have come from outside and are called exotic plants. These plants have been brought from Sino; Tibetan, African and Indo- Malayasian areas. These plants were brought as decorative garden plants in India. These plants grow rapidly as weeds under hot-wet tropical conditions. These rapidly multiply so that it is difficult to eradicate these.

Lantana and water hyacinth are two such species. Water Hyacinth is known as “Terror of Bengal”. It has choked up all the watercourses like rivers, streams, tanks, canals, etc.

Question 2.
How can foreign plants be harmful for us?
Answer:
The exotic plants have following disadvantages:

Our useful domestic vegetation can get destroyed.
It requires lot of money to destroy these exotic plants.
These spread diseases and are a hazard to public health.
It can pollute our water resources.
It can reduce our fertile land pastures and destroy the forest areas in the country.

Question 3.
What are the main reasons for our natural vegetation not remaining actually natural?
Answer:
Most of present vegetal cover in India is not really natural. A considerable part of the original cover has been destroyed or changed due to human settlement and use of the land. Much of vegetation is low in quality and content. The original natural vegetation survives only in inaccessible areas of the Himalayas and Thar Desert. In other parts of the country, the vegetation is not ‘natural’ in the real sense of the term.

Question 4.
Write a short note on Deciduous or Monsoonal Vegetation.
Answer:
The vegetation that sheds its leaves in order to have excessive evaporation, before the start of the hot season, is called Deciduous or Monsoon vegetation.

According to rainfall, the vegetation can be subdivided into two such types:
1. Moist Deciduous Forests. This type of vegetation is found where the annual rainfall is 100 to 200 cms. The vegetation is not much dense and the trees can achieve the height of 30 m. Teak, sandal are the main trees.

2. Dry Deciduous Forests. This type of vegetation is found in areas having rainfall between 50 to 100 cms. Its long belt starts from Punjab and goes up to Deccan plateau. Kikar, Jand are its main trees.

Question 5.
What type of vegetation is found in Eastern Himalayan region?
Answer:
In Eastern Himalaya, we find 4000 species of flowers and 250 species of ferns. Height, Temperature and Rainfall has great impact on the type of vegetation:

Upto an altitude of 1200 metres, we can find deciduous vegetation and mixed forests.
Upto the altitude from 1200 to 2000 metres we find desert evergreen forests. Sal and Magnolia are the main trees.
Due to decrease in temperature at a height of 2000 to 2500 metres are found temperate type of vegetation. Oak, Chestnut, Laurel, Birch, Maple, Alder are the main trees.
At an altitude between 2500 to 3500 metres, we find coniferrous trees. It includes Silver Fir, Pine, Spruce, Deodar, Rendoderan, Blue pine as main trees.
After some more height short natural grass (Alpine grass) and different types of flowers can be seen.

Question 6.
How does natural vegetation act as a boon for industries?
Answer:
Natural vegetation provides the basis for many industries. The main industries based on forests are like this.

Match Industry. Soft wood is used to manufacture match boxes.
Lac Industry. Insects provide lac on trees and is used for records, polish, electrical goods.
Paper Industry. Bamboo, eucalyptus, and many types of grass are used in paper industry. Bamboo is found in Terai region.
Warnish and paints. Warnish and paints are prepared from resin which comes from forests.
Medicines. Many important medicines are made from forests, e.g. Quinine from cincona. Other Industries: Forests provide raw material for many industries like pencils, boxes, sandal oil, furniture and sports goods.

Question 7.
What have been the implications of indiscriminate cutting of forests in the country?
Answer:
Natural vegetation plays an important role in our life. There has been great deforestation during the last four years which can result in the following disadvantages:

Deforestation has great impact on ecological balance.
It can create problem of soil erosion due to floods on mountain slopes as well as on plains.
The northern parts of Punjab are facing the problems of soil erosion.

(B) Animals

Question 1.
What steps are being taken for protection of animal life in India?
Answer:
Our rich wild life is rich heritage formed through centuries. It must be preserved. Many of the fauna are found only in India such as swamp deer, the one horned rhinoceros, the bison, Kashmiri stag, Nilgai, etc. These rare species are in danger of extinction. Wild life is a gift of nature and a thing of beauty. Wildlife Act provides for the protection and conservation of these species. For this zoos, national parks, bio-reserves, tiger reserves have been established in India.
PSEB 10th Class SST Solutions Geography Chapter 4 Natural Vegetation, Wild Life and Soils 2

Nilgiri Bio-reserve. This is the first reserve set up in the country in 1986.
Nanda-Devi Bio-reserve in Uttranchal Himalayas in (1988).
Nokrek in Meghalaya
Andaman-Nicobar Bio-reserve.
Valley of flowers in western Uttranchal
Gulf of Mannar in Tamil Nadu
Thar desert in Rajasthan
Rann of Kutchh (Gujarat)
Kaziranga and Manas Park in Assam.

Question 1.
What is the contribution of Primary Rocks in the formation of soils?
Answer:
Sedimentary rocks are found in Northern plains and igneous rocks are found in Indian plateau. Their composition is different and different types of soils are formed. The colour, texture and composition of soil depends upon the time factor the rocks have suffered a type of climate. In West Bengal, Bacteria help in the formation of soils. But in Rajasthan, the fertility of soil decreases due to absence of vegetation. In areas of heavy rainfall and strong winds, soil erosion is active. So the fertility decreases.

Question 2.
What should be done to increase the fertility of soils?
Answer:
The following methods should be used to improve the fertility of the soils:

Methods should be adopted to check soil erosion
Manures and chemical fertilizers should be used to maintain the fertility of soils.
Crop rotation should be practised.
Scientific methods of cultivation should be used.
Land should be kept fallow to retain its fertility.
Suitable combination of crops should be cultivated.

Question 3.
Write a short note on Peat or Marshy Soils.
Answer:
Peat soils cover an area of 1500 sq. km. It is found in Sundar Bans, the coastal area of Orissa, coastal areas of South Tamil Nadu, Central Bihar, Almora in Uttranchal. It is black and acidic. It is called Black soil in Kerala. Sometimes it takes the form of blue soils due to excess of bacteria.

Question 4.
What are the different types of Soil erosion?
Answer:
Soil Erosion. Soil erosion is of two types:

Types of Soil Erosion:

Sheet Erosion. When the soil is washed away in thin layers by water or wind, it is called Sheet Erosion. Fine silt and clay is removed from the top soil.
Gully Erosion: It is done by running water by cutting channel. Gullies and ravines are formed by rapid run off. Badland is formed over clay soils in Chambal Valley.

Question 5.
What are the causes of soil erosion?
Answer:
Causes of Soil Erosion:

Steep slopes. Steep slopes affect the rapidity of running water. On steep slopes, intensity of soil erosion increases.
Torrential rainfall. Heavy rainfall loosens the soil particles.
Strong winds. Winds and dust storm blow away soil in dry areas. This process is known as deflation.
Over-grazing. Due to over-grazing, the vegetation becomes too thin to protect the soil. Rain and wind can easily erode the loose soil.
Over-cropping. Crop rotation maintains soil fertility. But over-cropping and shifting cultivation renders soil infertile.
Deforestation. Deforestation means the removal of forest cover and it exposes the area to soil erosion. Reckless cutting of trees has resulted in soil erosion by Chos along the Siwalik hills. Human misuse of the land through wrong farming practices, deforestation, etc. leads to the removal of soil cover.

Question 6.
What are the agents of soil erosion?
Answer:
Wind, water, glaciers are the agents of soil erosion.

III. Answer each of the following questions subjectively:

Question 1.
Explain the classification of natural vegetation of India on various bases.
Answer:
Natural vegetation of India can be divided into the following five parts on the basis of geographical factors:
1. Evergreen forests or tropical evergreen forests. Evergreen forests are found in those parts of India where the average annual rainfall is 200 cms or more. These forests are mostly found in the Tarai region of the Eastern Himalayas, Western Ghats and Andaman islands.

2. Deciduous forests or monsoon forests. These forests are found in those parts of India where the average annual rainfall is between 60 and 200 centimetres. These forests are mainly found on the lower slopes of the Himalayas, Chotanagpur, Gangetic Valley and the eastern slopes of the Western Ghats.

3. Semi-desert forests. Such forests in India are found in Rajasthan, Western Haryana, Southwestern Punjab and Gujarat.

4. Desert or thorny forests. Thorny bushes are the typical vegetation of such forests. Such forests are found in parts of Rajasthan and Kutch.
PSEB 10th Class SST Solutions Geography Chapter 4 Natural Vegetation, Wild Life and Soils 3
5. Forests of Delta regions or Tidal forests. Such forests are found in the deltas of the rivers. Such forests in India are found in the deltas of Mahanadi, Godawari, Krishna, Cauvery, Ganga and Brahmputra rivers.

6. Mountain forests or the natural vegetation of the Himalayas. Forests of this type are found on the slopes of the mountains.

Question 2.
How is natural vegetation classified on the basis of Geographical elements in the country? (Pb. 2005, 06)
Answer:
There .are many variations of soil and climate in India. This has given rise to many types of forests. The forests in India can be divided into the following main types:
1. Evergreen forests or the tropical evergreen forests. Evergreen forests are found in those parts of India where the average annual rainfall is 200 cms or more. These forests are mostly found in the Terai region of the eastern Himalayas, Western Ghats and Andaman islands. The chief trees of these forests include Mahogany, bamboos, cane, rubber and cinchona. The wood from these trees is used for making furniture, houses and boats.

2. Deciduous forests or monsoon forests. These forests are found in those parts in India where the average annual rainfall is between 60 and 200 centimeters. These forests are mainly found on the lower slopes of the Himalayas, Chhotanagpur, Gangetic valley and the eastern slopes of the Western Ghats. The chief trees found in these forests include teak, sal, sesoo, mango, sandal and cotton tree. These trees shed off their leaves in summer.

3. Semi-desert forests. This type of forests are found in those parts of India where the average annual rainfall is between 20 and 60 cms. Such forests in India are found in Rajasthan, Western Haryana, South Western Punjab and Gujarat. Acacia and date palm are the typical trees of these forests.

4. Deserts or thorny forests. Such vegetation or forests are found in those parts of India where the average annual rainfall is less than 20 cms. Thorny bushes are the typical vegetation of such forests. Such forests are found in parts of Rajasthan and Kutch.

5. Forests of Delta regions or Tidal forests. Such forests are found in the deltas of the rivers. There is ample water and the soil is also fertile. Such forests in India are found in the deltas of Mahanadi, Godavari, Krishna, Kaveri, Ganga and Brahmputra rivers. Such forests are found in the states of West Bengal, Orissa, Andhra Pradesh and Tamil Nadu.

6. Mountain forests or the natural vegetation of the Himalayas. Forests of this type are found on the slopes of the mountains. The nature of forests changes with the height and the amount of rainfall.

Question 3.
Describe the benefits of natural vegetation to the country.
Answer:
Importance of Forests:
Forests are a valuable rersource; like a river system, it is a multiple resource. Forests provide mankind with a number of products. Forests have greatly influenced human activities. Modern civilisation depends more and more on forests.

Following are the direct and indirect advantages of forests:

Forests provide many things to meet our food requirements like wild fruits, nuts, berries, etc. Many tribes are dependent on gathering of these products in forests.
Forests are a source of timber for house building, furniture making, ship building, etc.
Forests supply about 40% of fuel of the world. Wood has been the major source of fuel in houses, smelting industries and running locomotives.
Softwoods supply raw materials for wood pulp, paper, rayon industries.
Many products like rubber, pitch, gum, tanning materials, cork, camphor, fir, herbs, etc. are gathered from forests.
Forests provide plywood and fibre wood for packing purposes.
Forests help in rainfall by capturing moisture in the air. These affect the climate of an area,
Forests prevent Soil erosion and floods.
Forests increase the fertility of soil, help agriculture and maintain ecological balance.
Forests provide shelter to wild animals and help recreation, wild life and hunting.
They check the advance of deserts.

Question 4.
Which elements determine the texture of soil?
Answer:
The formation of soils depends upon the following factors:

Bed rocks. Sedimentary rocks are found in the Northern plain while igneous rocks are found in peninsular India. These rocks have a variety of minerals which add to their fertility.
Climate. Colour, structure and composition of soils depend upon climate. West Bengal has fertile soils due to chemical processes. But Rajasthan has less fertile soils due to absence of vegetation. Areas with heavy rainfall and strong winds have soil erosion and the soils are less fertile.
Slope. Slope also affects the development of soils. Land slide occurs in hilly areas due to fast running water and gravity. Therefore, slopes are not fertile, but the valleys of Indus, Ganga and Brahmaputra are fertile.
Natural vegetation. Vegetation provides Humus which makes the soils fertile. India has a large area under cultivation. Vegetation is.not adequate. Only 5% to 10% bacteria is available. So soils are not very fertile.
Period. Time plays an important factor. Soils receive every year humus, sediments, bacteria, etc. Soil formation is a slow process which takes thousands of years.

Question 5.
Discuss the various types and characteristics of soils found in India.
Answer:
India is primarily an agricultural country. The soils of India are classified on the basis of bed rocks and climate conditions.
1. Black Soils: Black soils are mainly found over the Deccan Lava tract including Maharashtra, Madhya Pradesh, Gujarat and Andhra Pradesh. These soils have been formed due to weathering of Lava rocks. These soils cover an area of about 5 lakh sq. km. These soils are rich in lime, iron, magnesia and alumina. These are also called ‘Regur Soils’. These soils are most suitable for cotton cultivation and are known as ‘Black Cotton Soils’.
PSEB 10th Class SST Solutions Geography Chapter 4 Natural Vegetation, Wild Life and Soils 4
2. Red Soils. These soils are found in Tamil Nadu, Karnataka, Andhra Pradesh and areas on periphery of Deccan Plateau. These soils have been formed due to decomposition underlying igneous rocks.

3. Laterite Soils. Laterite soils are found on the highland areas of the plateau. These are found in Karnataka, Kerala, Tamil Nadu and hilly regions of Assam, Rajmahal hills and Chottanagpur plateau. Due to monsoonal climate (wet and dry seasons alternatively occurring), there is the leaching of soils.

4. Alluvial Soils. These soils have been deposited by the rivers in river valleys of Mahanadi, Godavari, Krishna and their deltas. These are deep and fertile soils. These are dark soils.

5. Desert Soils. These soils cover 2 lakh sq. km. from dry areas of Rajasthan, Gujarat, Punjab and Haryana. These sandy soils are suited to cultivation of jowar, bajra, cotton, wheat, etc.

Question 6.
What is Soil Erosion? Why is it caused? What is its regional distribution? How can it be checked? (Pb. 2008)
Answer:
Causes of Soil Erosion:

Steep slopes. Steep slopes affect the rapidity of running water. On steep slopes, intensity of soil-erosion increases.
Torrential rainfall. Heavy rainfall loosens the soil particles and scoopes out the soil forming gullies and ravines. This gives rise to a dissected surface called badland as in Chambal Valley of India.
Strong winds. Winds and dust storms blow away soil in dry areas. This process is known as deflation.
Over-grazing. Due to over-grazing, the vegetation becomes too thin to protect the soil. Rain and wind can easily erode the loose soil.
Over-cropping. Crop rotation maintains soil fertility. But over-cropping and shifting cultivation renders soil infertile,
Deforestation. Deforestation means the removal of forest cover and it exposes the area to soil-erosion. Reckless cutting of trees has resulted in soil erosion by chos along the Shiwalik hills. Human misuse of the land through wrong farming practices, deforestation, etc. leads to the removal of soil cover.

Soil conservation. Soil is a fundamental natural resource. Soil formation is a slow process, but it is easily lost by soil erosion. In fact, more soil is being lost each year than Nature makes. Soil erosion must be checked. Sound farming practices and measures be adopted to conserve, protect, renew and maintain soil fertility.

These methods constitute soil conservation.

Afforestation. In some areas, the original vegetation cover has been removed.
It has resulted in soil erosion as along Shiwalik Hills. In such areas, trees should be planted (reforestation) to hold the soil. Afforestation is needed in new areas to check the surface run off. Advance of deserts can be checked by planting trees along the margins of deserts.
Controlled grazing. The number of animals to be grazed on slopes should be
according to the carrying capacity of the pastures. It gives time for the grass to grow again.
Terraced Agriculture. Slopes must be cut into a senes of terraces (fields) for cultivation. Outer walls at edges are made to slow down the flow of rainwater.
River Dams. River Dams are built in the upper course of rivers to control floods and check soil erosion.
Contour ploughing. Contour ploughing, terracing and bunding is done to check soil wash on slopes. Ploughing is done at right angles to the hill slopes.
Crop rotation. Crop rotation system be applied and the land should be left fallow for some time. Soil fertility can be maintained in this way.
Other methods. In areas of heavy rain, basin type of cultivation is adopted.

Short Answer Type Questions

Question 1.
What is Soil? How is it formed?
Answer:
The loose and unconsolidated material which forms the upper layer of the crust is called soil. It is found in layers or horizons. Its thickness varies from some cms to meters. It consists of many mineral and organic particles, humus, bacteria, etc. Soil formation is a slow process. Soil is formed through the chemical and mehanical weathering of rock cover. Parent materials derived from rock cover and humus together lead to soil formation. Soil is the end product of the physical, chemical, biological and cultural factors which act and react together.

Question 2.
What are the major factors in the formation of Soil?
Answer:
The formation of soil depends upon many factors. The major factors are:

Parent Material
Climate
Surface features of relief
Slope of the land
Natural vegetation.

Question 3.
What are the characteristics of Alluvial Soils?
Answer:

Alluvial soils are deposited by rivers.
These soils are limited to river basins and plains.
These are very fertile soils.
These consist of fine grained clay and sand.
These soils are rich in potash, but poor in phosphorus.
These are generally deep soils.

Question 4.
Which type of soils are formed as a result of wide diffusion of iron in the rocks? Explain two important characteristics of these soils of India.
Answer:
Red soils are formed as a result of wide diffusion of iron in the rocks.

Characteristics of Red Soils. These soils are found in Tamil Nadu, Karnataka, Andhra Pradesh and areas on periphery of Deccan Plateau. These soils have been formed due to the decomposition of underlying igneous rocks. The red colour of these soils is due to oxidation and diffusion of iron in hard crystalline rocks. These are given to the cultivation of millets, pulses, linseed, tobacco etc. These soils cover the largest area in Peninsular India. These soils are poor in lime, nitrogen and humus. Fertilizers are added to make these soils fertile.

Question 5.
Which exotic species is known as ‘Terror of Bengal5? Why is it called so?
Or
Why does exotic flora become a problem for us? Name two such species.
Answer:
Nearly 40% of plant species found in India have come from outside and are called exotic plants. These plants have been brought from Sino-Tibetan, African and Indo – Malayasian areas. These plants were brought as decorative garden plants in India. These plants rapidly multiply so that it is difficult to eradicate these. These reduce the useful land cover. These prevent the growth of economic plants. These spread diseases and are a hazard to public health. Lantana and water hyacinth are two such species. Water hyacinth is known as “Terror of Bengal”. It has choked up all the water courses like rivers, streams, tanks, canals, etc.

Question 6.
What is the need for conservation of forests?
Answer:
Increasing human and animal population has adverse impact on natural vegetation. Areas which were once covered with forests, have now become semi-desert. Even Rajasthan has forests. Forests are essential for ecological balance which in turn is essential for human survival and development. For balanced ecology and healthy environment, at least one third of the land of India must be kept under forest. Unfortunately we do not have even one fourth of the total area under forest. The need for a policy for conservation and mangement of forest resources, therefore, demands no emphasis.

Question 7.
What are the aims of National Forest Policy?
Answer:
A new National Forest Policy was adopted in 1988 to stop the further decrease in the forest cover.

The policy aimed at bringing 33 percent of India’s landmass under forest cover. The world coverage was 27 percent, and India’s own coverage at that time was only 19 percent.
The policy further stated that efforts would be made to maintain environmental stability and to restore forests where ecological balance was disturbed.
The other objective was to conserve the natural heritage of the country, its biological diversity and genetic pool.
The policy further aimed to check soil erosion, an extension of the desert lands and reduction of floods and droughts.
Other objectives of the policy were to increase the forest cover through social forestry and afforestation denuded and unproductive land, increase in productivity of forests to make timber, fuel, fodder and food available to rural and tribal populations dependent on forests and encourage the substitution of wood.
Lastly it emphasized the creation of a massive people movement involving women to encourage planting of trees and stop felling of trees.

Long Answer Type Questions

Question 1.
What is Soil Erosion? In which different ways does it occur?
Answer:
Soil Erosion. It is the destruction and removal of top soil by running water, wind, etc. Soil erosion has become a serious problem in many areas. Soil formation is a slow process and takes thousands of years to develop soil, but it may be removed in a matter of a few years. Soil erosion results from the following causes ;

Causes of Soil Erosion:

Steep Slopes. Steep slopes affect the rapidity of running water on steep slopes, and the intensity of soil erosion increases.
Torrential Rainfall. Heavy rainfall lessens the soil particles and scoops out the soil-forming gullies and ravines. This gives rise to a dissected surface called badland as in the Chambal valley of India.
Strong Winds. Winds and dust storms blow away soil in dry areas. This process
is known as deflation.
Over-grazing. Due to over-grazing, the vegetation becomes too thin to protect the soil. Rain and wind can easily erode the loose soil.
Over-cropping. Crop rotation maintains soil fertility. But over-cropping and shifting cultivation render soil infertile.
Deforestation. Deforestation means the removal of forest cover and it exposes the area of soil erosion. Reckless cutting of trees has resulted in soil erosion by chos along the Shiwalik hills. Human misuse of the land through wrong farming practices, deforestation etc. leads to the removal of soil cover.

Question 2.
What factors control the diversity and growth of fauna and flora?
Answer:
The growth, types, and diversity in flora and fauna kingdom is due to the following factors:

Temperature
Sunlight
Precipitation
Soil
Relief

1. Temperature. The character and extent of vegetation are mainly determined by temperature along with humidity in the air, precipitation and soil. On the slopes of the Himalayas and the hills of the peninsula above the height of 915 metere, the fall in the temperature affects the types of vegetation and its growth, and changes it from tropical to subtropical temperature and alpine.

2. Sunlight. The variation in sun’s radiant energy at different places is due to the difference in latitude, season and duration of the day. Due to long duration of sunlight, trees grow faster in summer.

3. Precipitation. Almost the entire rainfall occurs by the advancing south-west monsoon (June to Sept.) and retreating north-east monsoons. Areas of heavy rainfall have more dense vegetation as compared to other areas.

4. Soil. Changes in soil conditions have given rise to peculiar types of vegetation in many areas such as mangrove forests swamps and sandy coastal forests.

5. Relief. It is another important factor affecting vegetation. Plains, plateaus and mountains have different types of vegetation.

So long as the players ambitions to take part in A class matches at the earliest do not acquire knowledge about important strokes of hockey, it is difficult for them to enjoy the game. I think if the newly trained players before playing in matches leam to use hockey in dribbling the ball on the ground, it will be a good beginning for them.

There is no hard and fast rule regarding the position of head, foot and hands in taking different types of strokes. But in taking an easy stroke the foot work plays an important role. First of all, a player should know how to hold the stick properly. One can leam other rules of taking strokes automatically while practising in individual and small groups. It is essential for complete success that a player should do all practice exercises at a slow pace. Then gradually he should increase his speed.

The important strokes are as follows:

Push-stroke is taken by the wrist. In this stroke the left hand is on the upper part of the handle, and the right hand remains in the middle of the stick, and the shoulders should remain directly behind it. The ball should be pushed along with the ground. This stroke is taken for small and sure ‘pass’ and it is of great creative importance.

Flick:
Both the hands remain with the stick in taking flick-stroke. This stroke is made with loose wrists. While flicking, the stick should remain totally with the ball. This stroke is taken without raising the stick behind. Normally, this stroke is made on the dribbling ball and is made, in place of a hit, for the quick exit of the ball. In the reverse flick, the reverse stick is used to move the ball to the right. It is a clever way to dodge the opponent.

When a player becomes expert in it, this type of his stroke is worth seeing. There was a time when Indian players playing with European teams used to stun them by making much use of the scoop. But recently it has been observed in a match played at New Delhi that making the best use of flick the opposing German players would succeed in throwing the ball over the Indian players, or, in other words, in entering their defence line. It was amazing that the ball was thrown inside 25 yards or more, as a result of which our defence line got no opportunity to make immediate defensive move there.

To take a powerful flick stroke it is essential that the hold on the stick is divided, that is, the hold of the right hand should remain slightly downward as compared to that of the left hand. There, is some difference in the rule to make a short distance flick stroke. Our players should be well-versed in this art because it is the best answer to the ‘player to player’ modern technique.

It is an attractive and the most useful stroke, but it needs regular practice and powerful wrists. The following exercises should be done to make the wrists more powerful:

(1) Hold the upper part of the stick with the right hand, and a little below, with the left hand. Turning the stick a little towards right push the ball. In the beginning of the stroke, the pressure of the body’s weight is on the left foot and the right shoulder turns a bit, and with it the stroke is made with the jerk of the wrist. In order to put this stroke in practice dribble the ball in the size of a circle with reverse-stroke.

(2) By remaining in that position and holding the stick only with the left hand, move the ball forward in the same manner. These two types of practice exercises are very essential, particularly for those Indian players who are totally ignorant in“left flick” or “push”. They will also provide that strength to the left hand which is essential for the flick-stroke.

This stroke is very useful from the viewpoint of giving high speed to the ball and for the quick exit of the ball. Through this stroke the player hides the direction of his ‘pass’ and also gets the essential strength for the variety of left hand.

Scoop:
This stroke is intentionally made to throw up the ball. In this stroke, the slightly bent stick remains behind the ball a little above the ground, and the two hands of the player on the stick remain far away from each other. If some problem arises in the play while making this stroke or when the ball falls on the ground, it should be deemed as infringement of rules. Though for a left – winger to dodge his opponent by throwing the ball on his stick, this stroke is very useful, yet the use of this stroke should be made occasionally. This stroke is very useful on a heavy, muddy playground.

Drive:
It is wrong notion that it is essential to raise the stick over the shoulder in any direction to hit the ball hard. The fact is that the ball reaches its destination very quickly with a hit made by the slightly backward raised stick. The speed and the strength of the hit depends upon the player’s foot work and the strength of the wrists at the time of hitting the ball. One should save oneself from the player’s undercut and the hit from below as these strokes are against the rules.

Lunge:
While making this stroke, the player holds the stick in one hand, his arms are completely drawn, the body leans over one foot and knees are bent. When the opposing player is away from the combat-distance this stroke is used to save the ball from his stick. Through this stroke the forward players can stop the ball from going out of the side line and goal line.

Jab:
This is a one-handed stroke. It can be taken either with the right or the left hand. This stroke is used to push the ball. This is a speedy forward activity of pushing the ball in which the player holds the stick in one hand and his arm remains extended forward. When two opposing players move forward with the aim of snatching the ball, use of this stroke is made to push the ball out of their reach before either of them snatches it.

For the Practice of Jab and Lunge

(a) By holding the stick in one hand and extending the arm fully, the player should do the practice of sharp jab.

(b) 1. The player should do the practice of playing reverse stroke by holding the stick in the left hand and by extending the arms fully. It will provide strength to the left wrist.

2. The two players, by placing the ball in between, should stand up. Then they should run fast to play the ball. Both the players should try to jab the ball with the right hand one before the other. Then they should try to lunge with the left hand. The practice of these two one-handed strokes is essential. When it is difficult to take the stroke with both the hands, only then the use of these strokes should be made. In other words, it.can be said that when the player needs “reach” more than the play of the game, these strokes prove to be very useful.

Dribble:
In hockey the art of dribbling is very important. A player cannot be perfect until he is not well-versed in this art. Dribbling should not be resorted to if it is adequate to hit or push the ball towards the colleague-player. The players of muddy, bouncing and uneven playgrounds should not do dribbling. The main aim of dribbling is to move the ball in possession to the left and then to the right.

The player, by maintaining this process, is to run fast. While doing dribbling a player should hold the stick in such a manner that the hold of his left hand remains upward the handle of the stick while the hold of his right hand remains 3-4 inches downward. The ball should remain one yard away from the player. While doing dribbling the stick should remain quite near the ball.

Fielding the Ball:
The experience tells that to stop the ball with the stick is very easy and quick process. That is why, hands are seldom used to stop the ball. It becomes essential to stop the ball with hands while taking the push for penalty corner or when the ball is in the air above the player’s waist in order to achieve the best result. If the ball is caught with hands, it should be immediately released.

While stopping the ball, the player should hold the stick in such a loose manner that his left hand remains on the handle of the stick and his right hand in the middle of the stick. In order to save the ball from swinging the hands should be left loose before the ball strikes. The ball is best stopped with stick.

When a rival forward player is running after the ball, then the best way to stop the ball for the player is to bring his body and stick to the level of the ball. If the player has the time and opportunity, then he should try to stop the ball from the right. Thus, he will be able to hit the ball easily.

The practice of Stopping and Hitting the Ball

Suppose two players ‘A’ and ‘B’ standing with a distance of 20 yards in between, and the centre line acts in their midst as the centre ‘R’ player hits the ball towards “A” players stops the ball and moves it back to ‘B’ again. The aim of both these players is to score the goal.

A goal is allowed if the all crosses the goal line of the rival player. In order to achieve his aim the player is to stop the ball properly and hit it back quickly. If the player has got a weak hit, then he should save himself, having entered the field of the rival player. By taking a quick hit within an area of 10 yards he will try to catch him in a difficult position.

Rules

If the player hits the ball across the side line or the 4 yards line drawn parallel to it, then the opposing player dan take the hit anywhere from the spot of crossing the ball.
If in the attempt to stop the ball, a player dribbles the ball over the line, then the opposing player can take the hit from the spot where the ball has dribbled.

The aim of practice is to improve the player’s art of stopping and hitting the ball. In order to make the best use of this practice, the players should remain on the look-out for the opportunity of quickly entering into and retreating from the field of the rival players.

The Practice of Stopping the Ball While Running

This practice should be done within 25 yards area towards the side line instead of the goal line. In order to catch each other in a difficult situation, both the players should hit the ball towards the left or right of the rival player. The ball going beyond reach will be stopped through lunge by the left and the right hand. The player is to learn this particular point.

Answer:
Mumbai and Chennai are two places of equable climate. Extreme climate is found in Amritsar and Jodhpur.

Question 7.
What is the importance of relief in determining the climate?
Answer:
It provides monsoon climate to whole country by acting as a climatic divide.

Question 8.
What is Jet Stream?
Answer:
Jet streams are high velocity winds at high altitudes. A jet stream is a narrow tubular shaped flow of wind along the troposphere. These have a velocity of 500 kms per hour and are located at 5 to 12 kms with an average location between 20°S to 40°N latitudes.

Question 9.
What do you mean by the term Monsoon?
Answer:
The word Monsoon is said to be derived from the Arabic word ‘Mausam’ meaning season. This word was first applied to the winds blowing over the Arabian sea. Monsoon implies seasonal reversal of the wind pattern over the years. Monsoon winds are those seasonal or periodic winds which changes their direction with the season. These winds blow from sea to land of six months during summer and from land to see during winter. Thus with the change of season the pattern of winds, temperature and rainfall changes.

Question 10.
What is Burst of Monsoons?
Answer:
The monsoon winds blow in south-west direction on the west coast. These are highly charged with water vapour. I’; advances rapidly over west coast. The rains begin rather suddenly in the first week of June. This sudden onset of rain is often termed as ‘Monsoon Burst’. This rainfall is heavily accompanied by thunder and lighting. The rain is so sudden and heavy that it appears as if a balloon of water has been burst.

Question 11.
What do you mean by ‘Loo’?
Answer:
Loos are hot dusty winds caused by low pressure in hot season. These are very hot and dry winds. These are called ‘Loo’ in local language.

Question 12.
What is Break in Monsoons?
Answer:
The dry period between monsoons is called Break.

Question 13.
What are monsoons?
Answer:
Monsoons are seasonal winds.

Question 14.
Where does ELNINO ocean current flow?
Answer:
Elnino current flows along the coast of Chile. It is studied for the reasons causing Monsoon.

Question 15.
What are ‘Kal Baisakhis’ or Norwesters?
Or
What are Kal Baisakhis?
Answer:
The destructive cyclones are called Kal Baisakhis in West Bengal.

Question 16.
What is meant by ‘Mango Shower’?
Answer:
North East Monsoons give rain in coastal areas of Kerala and Karnataka at the end of summer seasons.

Question 17.
At which places do the Monsoon winds coming from Arabian Sea and Bay of Bengal meet?
Answer:
The Monsoon winds from Arabian Sea and Bay of Bengal meet in Punjab and Himachal Pradesh.

II. Give reasons df the following in brief:

Question 1.
Mumbai is colder than Nagpur.
Answer:
Nagpur is situated away from sea. Whereas Mumbai is situated on the sea shore. There is equable type of climate in Mumbai due to effect of sea. Therefore there is less cold.

In the opposite of it, Nagpur has situated far away hum sea and free from sea effect. Therefore, extreme type of climate is found here.

Therefore, Nagpur is colder than Mumbai in winter.

Question 2.
Most of the average Annual rainfall in India comps in just four months of the year.
Answer:
In India, rainfalls mostly from mid June to mid September. The Monsoon winds coming from sea blow oyer India in these four months. These vapour laden winds give heavy rainfall in India.

Question 3.
Kolkata receives 145 cm of Rainfall whereas Jaisalmer receives only 12 cm of rainfall by the South West monsoons.
Answer:
The S. W. monsoons, from Bay of Bengal, first of all strike in Kolkata in West Bengal. These moisture laden winds give a heavy rainfall of 145 cms here. Jaisalmer lies to the west of Aravallis in Rajasthan. Aravallis lie parallel to S.W. Monsoons of Arabian sea. So these mountains fail to check S. W. monsoons. These winds move northward giving only 12 cms of rainfall.

Question 4.
Chennai receives most rainfall during winter season.
Answer:
Chennai is situated on Eastern coastal plain of India. It comes under the effect of North-East monsoon winds. These winds move from land to sea. But while crossing the Bay of Bengal, these pick up moisture. After striking Eastern ghats, these give heavy rainfall in winter. In summer, it gets less rain as it is a rain shadow area.

Question 5.
Chennai gets more rainfall in winters. Why?
Answer:
Chennai is located on the east coast of India. N.E. monsoons give here rainfall in winter. But in summer, dry winds blow which do not give more rainfall.

III. Answer the following questions in short:

Question 1.
What are the regional variations in the climate of India?
Answer:

Range of Temperature. There is a great variation in range of temperatures in different parts of India. Kerala and Andaman-Nicobar islands have a daily range of temperature i. e. 8° C. On the other hand in Thar Desert, if the day temperature is around 50° C, at night it may drop down very close to freezing point (0°C). The daily range of temperature is 50°C.
Direction of Rain Bearing Winds. Most of India gets rain in summer from S. W. Monsoons but, in winter Tamilnadu gets rain from N. E. Monsoons.
Form of Precipitation. Most of the country gets rain showers, while snowfall occurs in the Himalayas.
Amount of Rainfall. The annual rainfall is less than 10 cms in N. W. Himalayas and Thar Desert. It exceeds 400 cms. in Meghalaya. Mawsynram gets 1,141 cms rainfall.
Rainfall Regime i.e. Seasonal Distribution of Rainfall. There is a great variation in rainfall regimes in the country. Most of the country gets rain from advancing monsoons in summer. Tamilnadu gets rainfall in winter from N.E. monsoons. Some parts receive rainfall from retreating monsoons.

Question 2.
Give an account of the main reasons for the climatic variations in the country.
Answer:
There are great variations in the climate of India. It is not the same throughout the year due to:

Northern hilly region remains cold due to high altitude. Coastal areas have equable climate. Interior areas have high temperatures.
Windward slopes get high rainfall but rain shadow areas are dry.
In summer, winds blow from sea, to land. These moist winds give heavy rainfall. But as these move ahead, the rainfall goes on decreasing.
In winter the winds blow from land to sea. These winds are dry. Only S.E. coast of India gets rainfall. Other parts remain dry.

Question 3.
Why does the Pre-Monsoonal rainfall occur?
Answer:
In summer, equatorial low-pressure shifts towards Tropic of Cancer. To fill this space, the S.E. trades cross the Equator and get the direction of S.W. winds due to rotation of the earth. On 1st June, when these winds reach west coast, moderate rainfall occurs on windward slope of western ghats. This is called pre-monsoonal rainfall.

Question 4.
Describe India’s rainy season.
Answer:
Rainy season is also called the South West Monsoon season. Its time period is from the June to Mid September. The main characteristics of this season are:

A low pressure trough is developed in N.W. India.
Winds enter into the country from sea and give heavy rainfall.
The winds filled with humidity move at the rate of 30 km per hour and spread into whole country within one month.
Indian peninsula divides Monsoon into two parts-Monsoon winds of Arabian Sea and Monsoon winds of Bay of Bengal.
Most of rainfall in Western ghat and North East area of India is done by monsoon winds of Bay of Bengal.

There is more than 250 cm of rainfall on the winward slopes of western ghats. On the opposite there is more than 50 cm of rainfall on leeward slopes. Therefore due to this reason most of rainfall in Northeast states of India is highest and longer on hills of Eastern Himalayas. On the opposite the amount of rainfall goes on decreasing from East to West.

Question 5.
Which places receive maximum rainfall in India?
Answer:
The areas in which the rainfall is between from 1.50 to 200 cm are the places with highest rainfall. These are divided into three areas:

A narrow belt of 20 km width extends from western ghat to Kanyakumari in the North-South direction. It extends from the mouth of the Tapti River to the plains of Kerala.
Second belt extends along the southern slopes of Himalayas. It extends from Himachal Pradesh to the valley of Assam passing through Kumaon Himalaya.
Third belt extends in North-South direction. The hills of Tripura, Manipur and Mekar are in it. There is 200 cm annual rainfall in the belt.

Question 6.
Give any three characteristics of Indian Monsoon.
Answer:
See Question 2. Part IV.

Question 7.
In spite of being close to the Arabian Sea, why does Rajasthan remain dry?
Or
Why Rajasthan remains dry inspite of being close to Arabian Sea?
Answer:
The western part of Rajasthan is desert. It gets an annual rainfall less than 20 cms. This is due to the following reasons:

Rajasthan is under the influence of S.W. summer monsoons. The Aravallis system lies parallel to the direction of S.W. monsoons coming from Arabian Sea. So this mountain system is unable to check these winds. So western Rajasthan is practically dry. The southern part gets some rainfall.
This area lies at a great distance from the Bay of Bengal. The Bay of Bengal monsoons become dry and lose their moisture when they reach Rajasthan.
This area is away from the Himalayan region. So it does not come under the influence of monsoons giving rain in Sub-Himalayan region.

Question 8.
How do South East trade winds cause Monsoon rainfall?
Answer:
South East trade winds crossing the equator move towards India. The direction is changed due to rotation and move in S. W. directions. These reach Kerala coast on 1st June and give heavy rainfall. This is called Monsoon burst. These winds cover whole of India in one month and give rainfall.

IV. Answer the following questions subjectively:

Question 1.
Which elements affect the climate of India?
Answer:
The climate of India is mainly based on the following facts:
1. Distance from the equator. The places which are situated near the equator have high temperature whereas the places away from the equator do not have high temperature.

2. Height above sea level. The higher you go, the cooler it is. That is why the mountainous regions are cooler than plains.

3. Distance from the sea. The places near the sea have equable climate. Neither the summers are very hot nor the winters are cold, whereas in the parts away from the sea the summers are hot and winters are cold.

4. Winds. The winds have a great affect on the climate of India. The winds coming from the sea are full of moisture and they cause heavy rain. On the other hand, the winds that come from the land are dry winds and cause no rain.

5. Direction of the mountains. Wherever the mountains are located in the way of the winds, the winds are forced to rise against the mountains and cause rainfall. For example, when the moisture laden monsoon winds strike against Himalayas they cause heavy rain in West Bengal and Assam. On the other hand, the Aravali mountains run parallel to the direction of the monsoons that blow from the Arabian Sea and there is no rain in Rajasthan.

6. Nature of the soil. Sand gets heated and cooled quickly. The land is sandy in Rajasthan. That is why, the temperature is of extreme type there.

7. Slope of the land. If the land slopes towards the sun the rays of the sun will fall vertically and the temperature will be high. On the contrary if the land slopes away from the sun the rays of the sun will be slanting and the temperature will be low.

8. Forests. The regions with dense forests receive heavy rain, because the winds blowing over these forests gain moisture from the leaves of the trees, lose temperature and cause rain.

Question 2.
Describe the main characteristics of monsoon rainfall in India.
Answer:
Characteristics of rainfall in India: The average annual rainfall in India is about 110 cms. It is estimated that more than 85% of this rainfall is received in summer. The main characteristics of summer rainfall are given below:

Monsoonal rainfall. Most of the rain is received from S.W. summer monsoons during the period mid-June to mid-September. It is seasonal rainfall.
Uncertain rainfall. Summer rainfall is quite uncertain. Some times monsoons start early resulting in floods. Often the onset of monsoons is delayed resulting in drought. The early or late retreat of monsoons also results in serious droughts.
Unequal distribution. The rainfall is Unevenly distributed over the country. About 10% of the country gets more than 200 cms of rain while 25% of the country gets less than 75 cms of rain.
Heavy rainfall. Indian rainfall is heavy and downpouring type. It is often said, “It pours, it never rains in India.”
Relief rainfall. The amount of rainfall is determined by the presence of mountains. High mountains force monsoons to rise and cause rain.
No continuity of rainfall. Summer rain is characterised by breaks or dry spells.
Variable rainfall. Most of the areas have variable rainfall, as much as 30 cms. plus or minus. Due to variability in areas of low rain, famines occur.

Question 3.
Explain the characteristics of different seasons of India.
Answer:
The Indian Weather: The Indian sub-continent has a tropical monsoon climate. Monsoons dominate the climate of the sub-continent. Monsoons exercise a unifying influence on the weather conditions of India making it a single meteorological unit. India has a broad unity of monsoon type of climate having the same rhythm of season. The advance and retreat of monsoon divide the weather into different seasons.

(A) Seasons of N.E. Monsoons.

The Cold Season. December to February.
The Hot Season. March to May.

(B) Season of S.W. Monsoons.

The Rainy Season. June to September
The Season of Retreating Monsoon. October to November.

1. The Cold Season: The cold season lasts from December to February.
(a) Temperature. The sun is overhead at Tropic of Capricorn. The Indian sub-continent has winter season. January is the coldest month. The southern parts have warm conditions. (20°C) while low temperatures (10°C) are found in N.W. India.

(b) Pressure and Winds. High pressure is developed over N.W. part while a low pressure exists over the Indian Ocean with the result winds blow from land to sea. The out-blowing winds are Westerly in Northern plain and North Easterly over the rest of the country.

Rainfall. The N.E. Monsoons are off-shore winds and are dry. But these winds pick up some moisture crossing Bay of Bengal and give rain to S.E. coast of India. Some cyclones from Mediterranean Sea also bring a small amount of rain (10 to 20 cms.) to Northern plains. Night Frost is common in the N.W. parts.

2. The Hot Season. The hot season lasts from March to May.
(а) Temperature: As the sun’s rays fall vertical over Tropic of Cancer, the temperature begins to rise. The average temperature is above 30 C; the maximum temperature rises to 50°C in Banner (Rajasthan). The daily range of temperature rises in inland areas.

(b) Pressure and Winds. Intense heat results in the development of low pressure over N.W. India and Pakistan. A high pressure exists over Indian Ocean. S.W. Monsoons begin to blow from sea to land. ‘Norwesters’ and ‘Loo’ blow over Northern plains.

(c) Rainfall. Some areas receive convectional rainfall. The west coast also starts receiving rainfall. Most of the country is dry in the pre-Monsoon period.

3. The Rainy Season. The rainy season lasts from June to September.
(а) Temperature. The sun shines vertical over Tropic of Cancer. The temperatures are more than 30°C. With the onset of monsoon, there is a drop in temperature (5° to 10°C) with the result July is not the hottest month.

(b) Pressure and Winds. S.W. Monsoons blow from sea to land with a “burst’ on the West coast. It blows in two currents.

The Arabian Sea Current,
The Bay of Bengal Current

(c) Rainfall. S.W. Monsoons are rain giver as most of the sub-continent gets rainfall in this season. The Arabian Sea branch gives heavy rainfall on the West Coast, but Deccan plateau lies in rain shadow of Western Ghats. The Bay of Bengal branch gives heavy rainfall in Eastern Himalayas. The rainfall goes on decreasing up the Ganges valley with the decrease in moisture. Rajasthan is practically a desert.

4. The Season of Retreating Monsoon. S.W. Monsoons begin to withdraw from the sub-continent during the first week of October. The sun begins to move towards equator. There is a decrease in temperature. Hot and sticky weather is found. Some tropical cyclones are developed which give heavy rainfall in coastal areas. Cool-weather begins in N.W. India, but the Southern parts have an equable climate.

Question 4.
Compare the summer and winter seasons of India.
Answer:

The Indian Weather: The Indian sub-continent has a tropical monsoon climate. Monsoons dominate the climate of the sub-continent. Monsoons exercise a unifying influence on the weather conditions of India making it a single meteorological unit. India has a broad unity of monsoon type of climate having the same rhythm of season. The advance and retreat of monsoon divide the weather into different seasons.

(A) Seasons of N.E. Monsoons.

The Cold Season. December to February.
The Hot Season. March to May.

(B) Season of S.W. Monsoons.

The Rainy Season. June to September
The Season of Retreating Monsoon. October to November.

(c) Rainfall. Some areas receive convectional rainfall. The west coast also starts receiving rainfall. Most of the country is dry in the pre-Monsoon period.

(b) Pressure and Winds. S.W. Monsoons blow from sea to land with a “burst’ on the West coast. It blows in two currents.

The Arabian Sea Current,
The Bay of Bengal Current

Question 5.
Explain with the help of examples the impact of monsoon winds on life in India.
Answer:
Climate has a great effect on the economic, religious and social life of a country. It is also true in case of India. Monsoon is a powerful element of the climate of India and affects the life of people in many ways:
1. Economic effects. A lot of people depend upon agriculture. Monsoon rains are the basis of agriculture and backbone of the Indian Economy. If monsoons occur in time, it helps to increase agricultural production. When monsoons fail, there is a drought in India and the foodgrain reserves decrease. If monsoons start earlier,
the floods occur in different parts. If monsoons start late, the crops fail. With the result, it is often said, Indian budget is a gamble in monsoons.

2. Social effects. Monsoons affect the food, clothing, customs of people. With the
start of Monsoons, dress of people changes due to change in temperature. Monsoon winds complete a cycle in the country in which food and clothings change turn by turn. .

3. Religious effects. Many festivals are connected with monsoons. The sowing of crops and harvesting of crops are connected with festivals. Baisakhi in Punjab marks the harvesting of wheat crop and Bhangra is performed by farmers. In fact, the life of Indians revolves around Monsoons.

Question 6.
In spite of vast monsoon unity, there exist wide regional disparities in India. Explain with examples.
Answer:
The rainfall is unevenly distributed in India. Many regional variations are found in the distribution of annual rainfall. The distribution of annual rainfall shows two main trends:

From the coastal areas, the rainfall decreases towards the west and North-West.
The rainfall decreases towards the interior of the country.

The main factors controlling this distribution of rainfall are the presence of high mountains and the distance from the sea. The coastal areas get high rainfall. The west coast gets more than 200 cms. of rainfall while the east coast gets about 100 cms. of rainfall. The rainfall in the interior of peninsular India is as low as 50 cms. The Western Ghats, the Garo-Khasi hills, and the Sub-Himalayan region get more than 200 cms. of rainfall. But Rajasthan is dry as there is no high mountain to check S.W. Monsoons.

Distribution of Rainfall, The average annual rainfall of India is 118 cms. Regional variations in the distribution are found due to differences in relief of the country. Rainfall is unevenly distributed throughout the country.

India can be divided into the following, rainfall regions:

Areas of Heavy Rainfall. These areas get more than 200 cms. of annual rainfall. These include Western Coast and Western Ghats, Sub-Himalayas and the N.E. parts of India.
Areas of Moderate Rainfall. These areas get annual rainfall of 100-200 cms. These include West Bengal, Orissa, Bihar, Eastern parts of U.P. and Madhya Pradesh and coastal plains of Tamilnadu.
Areas of Low Rainfall. These areas experience an annual rainfall of 50-100 cms. These include Uttranchal, Haryana, Punjab, Gujarat, Peninsular plateau and Eastern Rajasthan.
Areas of Scanty Rainfall. These areas get less than 50 cms. of annual rainfall. These include Ladakh, S.W. Punjab, Southern Haryana, Western Rajasthan, Kutch and Thar Desert.

Short Answer Type Questions

Question 1.
How do Himalayas act as ‘climatic divide’ for India?
Answer:
The Himalayas act as a mountain wall to protect the sub-continent from the northern winds. These cold chilly polar winds cannot enter India, as these cannot cross the lofty Himalayas. So these mountains enable the Northern India to have a tropical climate. Thus the Himalayas act as an effective climatic divide.

Question 2.
Describe the origin of Monsoons and cause of its reversal of direction.
Answer:
Monsoon winds are caused due to difference in heating and cooling of land and water. In summer, the land gets more heated than sea resulting in a low pressure on the landmasses and a high pressure over seas. The winds blow from Sea to Land and in winter, from Land to Sea. Thus there is a reversal of wind direction according to seasons.

Question 3.
Distinguish between Western Jet Stream and Eastern Jet Stream.
Answer:
Western Jet Stream. The western jet stream is located in lower stratosphere over Southern Himalayas. In summer, its location is about 30° North. It lies north of the Tien Shan mountains in June.

Eastern Jet Stream. It lies over 25°N latitudes in winter. The western jet stream shifts southward due to shifting of the sun and takes the form of eastern jet stream. It is responsible for sudden burst of monsoons in summer in India.

Question 4.
What are the causes of storms occurring in May in N.W. part?
Answer:
A strong trough of low pressure is formed in N.W. India in May. These areas attract winds from the oceans. So the hot and dry winds meet these wet winds. With the result, storms originate. Strong winds prevail over the area. Sometimes, there is torrential rainfall and hailstones.

Question 5.
What would have been the climate of India, had there been no Bay of Bengal, Arabian Sea and Himalayas?
Answer:

Had there been no Bay of Bengal, there would not have been rainfall in S.E. coast (Tamil Nadu). Temperature would have been high.
Without the Arabian Sea, there would not have been so much rainfall on western ghats and west coastal plains.
Without the Himalayas, India would not have got monsoonal rainfall.

Question 6.
Why is not the monsoonal rainfall continuous?
Answer:
Summer monsoons are the cause of rainfall in India. The weather in S.W. monsoons is highly variable. It does not rain continuously throughout the period of summer monsoons. There are frequent ‘breaks’ or spells of dry weather, some of them lasting several days. This breaks the continuity of rain by S.W. monsoons.

The summer monsoons do not have great amount of moisture to give heavy rainfall. The amount of rainfall is increased by tropical depressions, convectional system, and jet stream. These cyclones are irregular and have a fluctuating pattern. The frequency of these cyclones determines the height of rainy season. The absence of these leads to a dry spell.

Question 7.
Give four examples of uncertainty and variability of Monsoons in India.
Answer:
Indian monsoons are variable and uncertain in time and place.

The number of rainy days sometimes increases and sometimes decreases,
Some years, it is heavy rainfall, hut some years get light rainfall,
The start and end of monsoons is early or late,
Some areas get high rainfall and some areas remain dry.

Question 8.
‘India would have been an arid land or desert, if there had been no phenomena of Monsoons.’ Explain it giving four points.
Answer:

Most of rainfall is obtained from S.W. Monsoons. Without these, India would have been arid.
Western coastal plain would have been dry.
Tamil Nadu, without N.E. monsoons, would have been dry.
Central and Eastern India would have been arid area.

Question 9.
Distinguish between Mango Showers and Kal Baisakhi.
Answer:
Mango Showers. Local rainfall in coastal areas of Kerala and Karnataka at the close of summer premonsoons is called Mango showers. It helps in early ripening of mangoes.

Kal Baisakhi. In summer, West Bengal and Assam get sharp showers by evening thunder-storms. These are called Kal Baisakhi. It means calamity of the month of Baisakh.

Question 10.
Why does the interior of Deccan Plateau and Rajasthan remain dry?
Answer:
In Rajasthan, Aravallis lying parallel to S.W. monsoons fail to check these. So they do not give rainfall. Deccan plateau is situated in rain shadow of western ghats. In this area, the descending winds become dry and do not give rainfall.

Question 11.
Name three characteristics of retreating monsoons.
Answer:
The months of October and November are known for retreating monsoons.

The monsoon low pressure trough becomes weaker and is replaced by high pressure.
The effect of monsoons over Indian landmass begins to shrink.
The direction of surface winds starts reversing.

Question 12.
Name three areas getting low rainfall.
Answer:
The areas of low rainfall include the areas which get an annual rainfall of less than 50 centimetres.

Western Rajasthan, Punjab, Haryana and Gujarat.
Interior of Deccan Plateau.
The region around Leh in Kashmir.

Question 13.
What is the effect of different seasons on life of people? Give three examples. .
Answer:

During cold winter seasons in Northern India, people wear woollen clothes in December.
Due to hot, dusty winds (Loo) it is uncomfortable in the month of May.
The moist laden monsoons give rainfall in June-July and weather becomes sticky.

Question 14.
What is Jet Stream? State its branches and speed. What are their effects?
Answer:
A Jet Stream is a high velocity wind in the upper air system. It has two branches- Westerly and Easternly jet streams. Westemly stream blows on 27°-30° N latitude. Its speed is about 110 km/hour to 184 km/hour. These bring cyclones with them over Northern India to increase summer rains.

Question 15.
What are western disturbances? What is their effect on crops?
Answer:
Western disturbances are low pressure depressions coming from Mediterranean sea. These blow over N.W. part of India during winter. These provide 10-20 cms of rainfall which is helpful to wheat and other rain crops. This small rainfall is locally known as Mahawat.

Question 16.
What do you mean by I.T.C.Z.? Explain its location and formation.
Answer:
I.T.C.Z. is Inter Tropical Convergence Zone. It is a brough trough of low pressure in Equatorial latitudes. It is formed due to convergence of N.E.’Trades and S.E. Trades.

It moves north or south of equator with the movement of the sun. It is situated on Ganga’ plain in summer and is called Monsoon trough also.

Question 17.
What is El Nino? What does it mean? What are its effects?
Answer:
El Nino is a periodic warm current blowing along the coast of Peru in Pacific Ocean. It is a Spanish word which means child. It increases the surface temperatures and weakens the trade winds. The difference between pressure in Pacific Ocean and Indian Ocean is used to compute the intensity of Monsoons; early or late monsoons.

Question 18.
‘Relief plays a major role in determining the climate of a place.’ Explain with examples.
Answer:
High mountains act as barriers for cold or hot winds. The Himalayas check the cold winds from Siberia from entering in India. High mountains like Himalayas cause rainfall by checking moist winds. The leeward side of a mountain remains in Rainshadow and is dry.

Question 19.
Which weather conditions govern the climate of India?
Answer:
(a) Pressure and surface winds
(b) Upper ah circulations
(c) Western cyclonic disturbances
(d) Tropical cyclones.

Question 20.
What is October Heat?
Answer:
The month of October forms a period of transition from the hot rainy season to dry winter conditions. The retreat of monsoons is marked by clear skies and rise in temperature. Day temperatures are high, but nights are cool and pleasant. The land is still moist. Owing to conditions of high temperature and humidity the weather is rather oppressive during the day. This is known as ‘October Heat’.

Long Answer Type Question

Question 1.
Describe the season of Advancing Monsoon in India.
Answer:
Advancing Monsoon. The four months of June. July, August and September form , the rainy season almost all over the country. This is called the season of‘Advancing Monsoons’. About 75% to 90% of total rainfall occurs in this season. This duration of the rainy season, however, goes on decreasing from south to north and from east to west. The rainy season is only two months long in North West, while it is nine months long in North East.

Origin of S.W. Monsoons. The low pressure conditions develop over the north western plains. By early June they are powerful enough to attract the trade winds of Southern Hemisphere. These south-east trade winds are Sea to Land winds. After crossing the equator these winds enter the Bay of Bengal and the Arabian Sea. After that, these winds blow over India. Passing over the Equatorial warm currents they bring with them moisture in abundance. After crossing the equator they follow a southwesterly direction. This is why they are known as south-west monsoons.

Burst of Monsoons. The rain-bearing winds are strong. They blow at an average speed of 30 km per hour. They over-run the country in a month’s time. The sudden approach of the moisture-laden winds is associated with violent thunder and lightning. This is known as “break” or “burst” of the mopsoons.

Branches of S.W. Monsoons. The Indian peninsula divides the monsoon into two branches.

The Arabian Sea Branch
The Bay of Bengal Branch.

1. The Arabian Sea Branch. The Arabian Sea branch of the monsoons strikes (Sahyadris) the Western Ghats. The windward side of the Sahyadris receives very heavy rains. Crossing the Western Ghats they blow over the Deccan Plateau and Madhya Pradesh. These winds give fair amount of rainfall in these areas. Thereafter, the jr enter in the Ganga Plains and mingle with the Bay of Bengal branch. Another part of the Arabian Sea branch strikes the Saurashtra peninsula and the Kutch. It passes over West Rajasthan and along the Aravallis causing only a scanty rainfall. In Punjab and Haryana too, it joins the Bay of Bengal branch. These two branches join together and cause rains in the Western Himalayas.

2. The Bay of Bengal Branch. The Bay of Bengal branch approaches the Burmese
coast and the southeast Bangladesh. But the Arakan Hills along the Burmese coast deflect this branch to enter the Indian subcontinent. The monsoons, therefore, enter West Bengal and Bangladesh from south and southeast instead of the south-westerly direction.

this branch splits into two parts under the influence of the mightly Himalayas and the thermal low in N.W. India.

One branch moves westward along the Ganga plains’ and reaches the Punjab plains.
The other branch moves up the Brahmaputra valley in the North and Northeast. It causes widespread rains in the North-eastern India. Its sub-branch strikes the Garo and Khasi Hills of the Meghalaya. Cherrapunji is situated at the head of a funnel-shaped valley in Khasi Hills. It gets the heaviest rainfall in the world due to its situation.

Distribution of Rainfall. Distribution of rainfall received from south-west monsoons is very largely governed by the relief or orography. For instance the windward side of the Western ghats gets a rainfall of over 250 centimetres. On the other hand the leeward side, receives 50 centimetres rainfall. The Northeastern States get heavy rainfall due to high Eastern Himalayas. The rainfall in the northern plains goes on decreasing from East to West. During this rainy season Kolkata receives about 120 centimetres, Patna 102 cm, Allahabad 91 cm and Delhi 56 cm.

Question 1.
Enlist information about Sutlej its tributaries and dams built on them.
Answer:
Sutlej river originates from a place called Rakshtal near Mansarovar lake at the height of 4630 metre in Tibet. When it crosses Himalaya mountain it makes deep gorges. It enters plains at Bhakhra and here Bhakhra dam has been made. From Nangal, Sutlej river moves in south direction and when it reaches Ropar, many seasonal choes, small rivers meet the main river. In Firozpur district, it enters Pakistan at Sulaiman, 60 km. away from Harike Pattan. Bhakhra dam, Kotla dam, Naptha Jhakhri and Nangal Dam have also been made on Sutlej river.

Tributaries of Sujtlej river. Beas and Kali Bein are major tributaries of Sutlej. At Makhu, Chitti Bein enters Sutlej river. Many dams and many headworks such as Ropar Headworks and Harike Headworks have been made on Sutlej river.

Question 2.
Give details of canal system of Punjab. How agriculture got benefitted by it?
Answer:
Most of Punjab’s population is engaged in agriculture or related occupations. Green Revolution was started in Punjab during the decade of 1960. Irrigation played an important role in the success of green revolution because now it was not possible for the farmers to solely depended upon rain. That’s why from time to time, Punjab developed its own canal system. There are 14500 km. long canals and 5 Headworks in Punjab. There are 10 canals in Punjab and these are Sirhind canal, Upper Bari Doab canal, Bist Doab canal, Bhakhra Mainline canal, Firozpur/Sirhind Feeder arrangement, Kashmir canal, Makhu canal, Shah canal, Rajasthan Feeder and Bikaner Canal. 8 out of 10 canals are given below :

Canal	Place of Origin	Length
1. Bhakhra Main Line	Nangal Bairaj	161.36 km
2. Rajasthan Feeder	Harike Headworks (Taran Taran)	149.53 km
3. Sirhind Feeder II	Harike Headworks	136.53 km
4. Sirhind	Ropar Headworks	59.44 km
5. Bist Doab	Ropar Headworks	43.00 km
6. Upper Bari Doab	MadhopurHeadworks	42.35 km
7. Eastern Canal	Hussainiwala Headworks	8.02 km
8. Shah Canal	Mukerian Hydel Channel	2.33 km

Advantages to Agriculture: This canal system proved to be quite fruitful for Punjab.

Its advantages are :

These canals provide water for irrigation throughout the year.
With the artificial means of irrigation, farmers are able to produce two or more than two crops in one year.
With more production of crops, income of farmers also increases.
Dams have been made on rivers and canals which provide water to farmers in case there is drought or no rain in the region.
Hydroelectricity have been made from Dams which is provided throughout the year to homes and industries.

Question 3.
Write a detailed note on the Choes of Punjab.
Answer:
Choes are seasonal rivers which get filled with water in the rainy season. There is a Kandi region in Punjab where there is existence of many choes. Many of these choes originate in Sailamingi hills. When rain comes, these choes get filled with water. Punjab Government is successful in filling up of many choes and their water is used in agriculture or somewhere else.

There are 93 choes flowing in the south west of Hoshiarpur district out of which many fall either in Kali Bein or Chiti Bein. There are many choes in Hoshiarpur district and few of them are quite important such as Taissan choe, Banea choe, Garhshankar Balachaur choe, Maili choe, Narialo choe, Nangal Shahida choe, Godpur choe, Dasuha choe. To control choes, Punjab Government started Kandi Area Development Programme. There are few seasonal nullahs in Punjab as well such as Patiala di Rao, Jaintiya Devi di Rao, Buddah Nullah etc.

Eastern Himalayas

Question 2.
Write a note on the origin and structure of the Himalayas. Are they still rising?
Answer:
Millions of years ago, the Himalayas were occupied by a geosyncline known as Tethys. It was sandwiched between two long landmasses—Angara land on the north and Gondwana land on the south. The Tethys seas stretched over the Northern plains in east-west direction. For millions of years, sediments were deposited in Tethys sea. These sediments were folded to form the Himalayas. The land masses of Angara land and Gondwana land drifted slowly towards each other. The horizontal forces worked from two opposite directions resulting in compression. It led to sinking of the Tethys sea.

The Indian plate was driven northwards and pushed beneath the Eurasian plate. When the two plates came closer, the Tethys sea’s crust fractured. The sediments buckled and folded to form the mighty fold mountains of the Himalayas. It has been observed that the ‘Himalayas are still rising.

Question 3.

Answer:

Western Coastal Plains	Eastern Coastal Plains
1. West Coast is a narrow alluvial plain with a width of 50-80 kms.It is uneven and wet.	1. The Eastern Coast has a wide plain with well developed delta 80 to 120 km wide. It is level and dry.
2. Beautiful lagoons are found on the Malabar Coast.	2. The Eastern Coast has only two or three lagoons.
3. The short swift rivers do not make any deltas on the western Coast. The Tapti and Narmada make estuaries.	3. The large rivers make wide deltas on the Eastern Coast. Mahanadi, Godavari, Krishana, Cauvery make well developed deltas.
4. Kandla, Mumbai, Marmugao, Mangalore and Cochi are major ports on West Coast.	4. Tuticorin, Chennai, Vishakhapatnam, Paradeep and’Kolkata are major ports on the East Coast.

Question 4.
Give a detailed description of the size, origin and regional division of India’s Northern plains.
Answer:
Extent. The great plain extends in between the Himalayas and the Peninsular plateau. It is 3200 km long and 150 to 300 km wide. Its average height is 150 metres. It covers an area of 7.5 lakh sq. km.

Formation. It is an alluvium filled trough. It has been formed by the deposition of sediments brought from the Himalayas by the Ganga, Sutlej and other rivers.

Main Characteristics :

It is a dead flat lowland. The maximum height above the sea level is 263 metres.
It has a gentle gradient \(\frac{1}{4}\) metre per km.
It has huge depth of alluvium.
A large number of rivers flow in this plain dividing it into Doabs.
It has fertile alluvial soils namely Khadar and Bangar soils.

Division of Northern Plain :

Bhabar and Terai. It is a long, narrow zone along the foothills. It is a pebble- studded zone. Swampy areas occur in Terai.
Punjab Plain. This plain has a slope in the South West direction. It has been formed by the deposition of sediments by Ravi, Beas and Sutlej rivers. Chos (seasonal streams) cause soil erosion in foothills of Shiwaliks.
Ganga Plain. This plain has been formed by the deposition of sediments brought by the Ganga and its tributaries. It can be divided into three regions—upper Ganga plain, middle Ganga plain and the lower Ganga plain. It occupies an area of about 3.5 lakh sq. km. Sunder Ban Delta is formed in the lower Ganga plain.
Brahmaputra Plains. These plains are situated in the Eastern part and are often known as Assam valley. The Brahmaputra river forms a large delta in Bangladesh.

The Great Indian Desert plain of the west. This covers the western part of the Aravalli mountains. This region has a sandy land, so it is also known as the Thar desert. This region gets very little rainfall, due to which the agriculture is not developed here. There are many saltwater lakes like the Sambhar, Didwana and Panchpadra, from which salt is extracted.

The formation of northern plains.
The northern plains lie in between the Himalayas and the peninsular India. It has been formed by the filling of the depression formed by Tethys sea. The Himalayan rivers after eroding the Himalayas deposited huge amount of silt and deposition in the ever-shrinking Tethys sea. This depression has been filled gradually to form northern plains or the Indo- gangetic plains. These rivers have deposited silt to form Ganga delta in Bangladesh. Due to continuous deposition, the delta is still advancing towards sea.

Question 5.
What is the extent and surface formation of the Peninsular Plateau? Describe its sub-division on the basIs”of slope of the land’.
Answer:
The Peninsular Plateau:
The Deccan plateau is the oldest structure of India. It is the core of the geology of India. It is surrounded by oceans on three sides. Therefore it is often called Peninsular plateau. It covers an area of 16 lakh sq. km. The average altitude of the plateau varies from 600 to 900 metres. Its limits are formed by the Aravallis in the North Rajmahal Hills and Shillong plateau in the East. There is Malda gap between Rajmahal hills and Shillong plateau. The southernmost point is known as Kanyakumari. It is an ancient, stable, hard block formed by igneous and metamorphic rocks. It was part of Gondwana land.

Division of Peninsular Plateau. A series of low hills, known as Satpura ranges between 21° N to 24° N latitudes divided the Peninsular plateau into two parts.
(a) Malwa Plateau
(b) Deccan Plateau.

(a) Malwa Plateau. The Malwa plateau covers a large part of central highlands. It extends from Aravallis in the West, Ganges valley in the North and East, and Vindhyas in the South. The Aravallis are residual mountains or Relict Mountains. Its highest peaks are Mt. Abu (1158 metres) and Guru Shikhar (1722 metres). This plateau includes Bundelkhand, Baghelkhand and Chambal valley. This Vindhyan plateau consists of long narrow ridges made up of Quartzite rocks. It extends upto Mahadeo Hills, Kaimur range, Maikal range, Rajmahal hills in the East. In the East lies Chotta Nagpur plateau drained by Damodar river. This plateau is the storehouse of minerals of India.

Are the different physical divisions of India separate and interdependent units or are they complementary to each other? Explain this statement with examples. (Important)
Answer:
India is divided into three major physiographic division i.e. the Himalayas, the Northern plains and the Peninsular plateau. The peninsular is the core of the geology of India. It is a stable block of hard rocks around which other physiographic divisions have been formed. The northward drifting of peninsular plateau led to the formation of Himalayas. The Himalayas adorn like a crown. These enclose the Indian sub-continent. Sediments brought down from Himalayas have been deposited to form the northern plains. The Gangetic plain is the cradle of Indian civilisation. Thus three physiographic divisions help to strengthen the forces of unity of our people.

1. The Eastern Coastal Plain. It extends from Mahanadi Delta upto Kanyakumari. Its width varies from 50 to 250 km. Mahanadi, Godavari, Krishna form broad deltas on this coast. Sand dunes and lagoons exist on this coast. Chilka lake and Pulicat lake are the two important lagoons. It is also known as Coromandel coast. The northern part, along the Orissa state, is known as Utkal coast.

2. The Western Coastal Plain. This is a narrow coastal plain 1500 kms long and about 10 to 50 km wide. It extends between the Arabian Sea and Western Ghats. It has three sub-divisions. Konkan coast from Gulf of Cambay to Goa, Kanara coast from Goa to Cochin, Malabar coast from Cochin to Kanyakumari. Lagoons and back waters along Malabar coast join together to form waterways. Vembnad is an important lagoon lake which is 63 km in length. Narmada and Tapti rivers make estuaries while Mumbai and Marmagao are deep natural harbours.

These plains are divided into the following parts:
(a) Gujarat coastal plain: A marshy area around Gulf of Kutch and Saurashtra. Gorakhnath is the highest peak with 1117 metres in height.
(b) Konkan coast: It extends from Daman to Goa; 500 km long and 50-80 km. wide. Mumbai port is in the Creek by Thana.

PSEB 10th Class SST Solutions Geography Chapter 7 Population 1

Question 2.
What are the factors that affect the distribution of population?
Answer:
Population in India is not evenly distributed. Many factors are responsible for this:

Fertility of the soil. The states in which there is a large fertile area the density of population is high. U.P. and Bihar are such states.
Amount of rainfall. The density of population is higher in regions of abundant rain. In northern India the amount of rainfall goes on decreasing from east to west. The density of population also goes on decreasing in the same direction.
Climate. Wherever the climate is congenial the density of population will be high. In Assam even though there is abundant rainfall but the density of population is low because the climate is unhealthy. The malaria is always there is an epidemic form.
Developed means of transportation. With development of means of transportation the business makes rapid progress and the density of population increases. The reason for high density of population in U.P., Bihar and West Bengal is the development of means of transportation.
Industrial development. At places where the factories are located the density of population also increases. The reason is that people like to live in those areas where industrial development takes place. They can carry on their business more easily in such areas and they have better chances of earning more money. That is why the density of population is high in Delhi, Mumbai and Kolkata.

Answer:
The percentage of male workers is 37.50 in India (about 1/3rd of population)

This is due to rapidly growing population. It increases the dependent population.
Females are not allowed to go out for work,
There is absence of female awareness and education.

Question 6.
Why is India known as a country of villages?

A large number of people ih India speak Hindi, understand Hiridiffe^bn if it is not their mother tongue. Hindi is the national language of India.

Question 8.
What are characteristic features of regional distribution of population?
Answer:
Characteristic features of regional distribution of population:

The distribution of population is uneven in India. There is dense population in river valleys and coastal plains. There is sparse population in hilly areas, deserts and drought affected areas. 16% of the area of the country, in the Northern plains only 3% people of India live. 94% of population lives on an area of 18% in plains. Only 2% population lives on an area of 6% in Rajasthan.
Most of the people live in villages. Only 31% people live in urban areas.
A large part of minorities live in sensitive border area. Along the N.W. border of India; Sikhs in Punjab and Muslims in J & K, form a majority community. Along the borders of China and Burma, in the North-East, mostly Christians are found. It has created many political, economic and social problems.
On the one hand, there is concentration of population in river valleys and coastal areas, but deserts, hilly areas are sparsely populated. It looks like a demographic divide.

Question 9.
Which are the states which have high density of population?
Answer:
There is dense population in Northern plain, western coastal plain, Eastern Coastal plain (Deltas). These areas have fertile soils and facilities of irrigation. So the population is dense. As we go westward, the rainfall goes on decreasing and the density of population also decreases. That is why the density of population in West Bengal is greater than that in Haryana and Punjab. Kerala has also high density because two or three crops can be grown due to high rainfall.

Question 10.
What are the causes of high density of population in plains?
Answer:
The density of population is high in plains. This is due to:

The Northern plain is fertile.
It has high rainfall.
It has many big industrial centres.
The means of transport are developed.
Coastal plain has facilities of fishing and foreign trade.

Question 11.
What are the areas of low density of population?
Answer:
Arunachal Pradesh is the ara of low density of population followed by Andaman and Nicobar, Mizoram and Sikkim as per the census 2011.

Question 12.
Name the areas of low density of population. What are the causes of low density of population?
Answer:
Thar Desert, Eastern Himalayas and Chotta Nagpur plateau are sparsely populated areas.

The soils are infertile or sandy or stony.
The means of transport are not developed
The climate is not healthy. It is either too hot or too cold. Himalayas get heavy rainfall.
Industries are not developed in these areas except Chotta Nagpur plateau.

Question 13.
Why is it necessary to study the structure of population?
Answer:
It is necessary to study the structure of population of a country due to:

We need different components of population such as age structure, sex ratio, occupational structure for the economic and social planning of a country.
The different aspects of population have a close relationship with development on the one hand, These are affected by population and on the other hand these affect population and ’development. For example, if the percentage of children and old age people is high in age structure, a country has to spend more on education and health facilities. On the other hand, a high percentage of working age group encourages the economic development of a country.

Question 14.
Name the areas with small population.
Answer:
Sikkim, Lakshadweep are the areas with small population.

Question 15.
What is the importance of study of age structure?
Answer:
These are the advantages of study of age structure of population:

By determining the 0-14 age group the govt, knows that there is need of expenditure on education, health and social services. So new schools, health centres and community centres are opened.
We know the number of eligible voters in the country which is vital for a democracy. There should be 58% voters per age group, but actually there are 60% of voters in the country.

Question 16.
What are the causes of low sex ratio in India?
Answer:
The sex ratio of India is 940 per thousand males. There is a general declining trend in sex ratio. The ratio in 1901 was 972, It was declined to 934 in 1981. This decline has been due to social evils in our society.

In our society, female child is neglected. Male population dominates in our society. There is high death rate among females. Death rate is particularly high among married women. Women labour migrates to some mining and industrial centres. It also results in declining sex ratio.

Question 17.
What are the causes of increase in urban population in India?
Answer:
The rapid growth of population has posed many socio-economic problems in different countries. The main problems are :

Food problem. Growth of population has led to shortage of foodgrains in many areas.
Agricultural production has increased due to new technology, yet many countries have to import agricultural products.
Housing problem. Housing conditions are poor in over-populated countries. People live in slum areas. Skyscrapers are being built in many Metropolitan towns.
Unemployment. Rapid increase in population leads to unemployment. Migration of people from over-populated rural areas has added to Unemployment.
Low standard of living. Per capita income is low in overcrowded areas so living conditions are poor. People do not afford to have basic necessities of life. Population explosion leads to poverty and a poor standard of living.
Dependent population. A large percentage of young people become dependent on a small working population.
Social problems. Many social problems arise due to overcrowding. Poor health and bad sanitary conditions lead to epidemics.

III. Answer the following questions subjectively:

Question 1.
Explain the regional structure of density of population in India.
Answer:
The distribution of population in India is unequal. According to 2011 census, the total population of India is 121 crore and the density of population is 382 persons per sq. kilometre. The density of population varies according to relief, climate and the agricultural productivity of the land. The density of population depends on the amount of rainfall.

The areas of sufficient rainfall can support a large number of people.
1. Densely populated areas. These areas have a density’of more than 400 persons per sq. kilometre. The high density areas make a girdle round the Deccan plateau. Right from Sutlej-Beas plain to Brahmputra valley, the density of population is very high.
(a) West Coastal Plain: Kerala has 859 persons per sq. kilometre density of population.
(b) East Coastal Plain: Tamil Nadu has a density of 555 persons per sq, kilometre.
PSEB 10th Class SST Solutions Geography Chapter 7 Population 5
(c) The Northern Plain: It includes West Bengal, Bihar, Uttar Pradesh, Punjab.

Factors favouring high density:

Sufficient rainfall
Fertile river valleys and deltas.
2 to 3 crops of rice in a year.
Irrigation facilities.
Healthy climate.
Rich in mineral and power resources.

2. Moderately populated areas. These include the areas with a density between 200 to 400 persons per sq. kilometre. These areas are surrounded by Eastern Ghats and Western Ghats. Haryana, Maharashtra, Andhra Pardesh, Karnataka, Gujarat, Orissa, Goa, Assam have a moderate density.

Factors for moderate density:

Agriculture is not developed due to thin and rocky soils.
Rainfall is uncertain.
Means of transportation are not developed.
Some areas have high density of population due to irrigation, lava, soils and mineral resources.

3. Sparsely populated areas.
These areas have a density less than 200 persons per sq. kilometre.
(a) North Eastern India. This region includes Meghalaya, Manipur, Nagaland, Sikkim and Arunachal Pradesh.

(b) Rajasthan Desert. Rajasthan has a density of 200 persons per sq. kilometre.

The hilly nature of the land.
Dense forests.
Low rainfall
Poor econoufic development.
Absence of minerals.
Lack of irrigation and agriculture.
Cold climate.

Question 2.
Explain in detail the state-wise structure of sex ratio in India.
Answer:
Sex ratio means’the number of females per 1000 males. Now-a-days, women have equal rights with men. In developed countries, the number of women is equal to number of men. In some countries sex ratio is 1050. The average sex ratio in developing countries is 964. In India, in 2011, sex ratio was 940, and is one of the lowest in the world.

State-wise sex ratio. Sex ratio is not uniform in all states. Only one state, Kerala, has sex-ratio of 1084 and Puducherry (1036) (Above the average). In other states, sex ratio is less than average.
PSEB 10th Class SST Solutions Geography Chapter 7 Population 7
It is clear that Northern States have low sex ratio which is a matter of concern.

Question 4.
What problems are arising due to increase in urban population in metro cities?
Answer:
The rapid growth of population has posed many socio-economic problems in different countries. The main problems are:

Food problem. Growth of population has led to shortage of foodgrains in many areas.
Agricultural production has increased due to new technology, yet many countries have to import agricultural products.
Housing problem. Housing conditions are poor in over-populated countries. People live in slum areas. Skyscrapers are being built in many Metropolitan towns.
Unemployment. Rapid increase in population leads to unemployment. Migration of people from over-populated rural areas has added to Unemployment.

Dependent population. A large percentage of young people become dependent on a small working population.
Social problems. Many social problems arise due to overcrowding. Poor health and bad sanitary conditions lead to epidemics.

Question 5.
Write a note on the cultural structures of population of India.
Answer:
1. Races. Ethnically, India consists of several races, the Dravidians, the Mongoloids, the Arayans and the Caucasians. In course of time these races have intermingled, losing many of original traits and acquiring new ones from others. And yet we notice a great diversity which is so characteristic of the Indian people. In fact, the richness and beauty of India culture lies in its diversity. Its spirit of tolerance, give-and- take assimilation makes it one of the distinctive cultures of the world.

2. Faiths. The Indian people follow different faiths. These do not follow regional, political and linguistic barriers. They speak different languages ^languages cut across race, religion, caste and often region. Notwithstanding these facial, religious linguistic arid regional diversities, we are all Indians first and Indians last. Ours is a plural society with a composite culture. It can be compared to a fine mosaic or to a garden with flowers of various colours and shades. This maintaining entity of each lends colour and beauty to the total cultural landscape of our country.

3. Religions. India is the home of Hindus, Muslims, Christians, Sikhs, Buddhists, Jains, Zorastrians and others. None of these people enjoy any special privileges on the ground of their religion. Nor do they suffer in economic, political or social life because of their faith in a .particular religion. All are equal before law and enjoy full freedom. All are bestowed with equal rights, .entailing corresponding responsibilities.

4. Languages. In India there are a large number of languages. Some of them are derived from Sanskrit while others are of Darvidian origin. The major Indian languages are Assamese, Bengali, Gujarati, Hindi, Kannada, Kashmiri, Malyalam, Marathi, Oriya, Punjabi, Sanskrit, Sindhi, Tamil, Telugu and Urdu. Of these, four languages of southern India-Tamil, Telugu, Kannada and Malyalam are of Dravidian origin.

5. National Language. It would be a mistake to conclude that everybody speaking any of these languages is Dravidian by race. Similarly, not all who speak languages of Sanskrit origin are Aryans. Generally, the people who lived in a given area over a long period of time adopted the language of that region as their first language irrespective of ethnic or any other considerations. A great number of people speak Hindi. Similarly, a large number of people are able to understand this language even if it is not their mother tongue. This has led to the adoption of Hindi as the official language of the Union Government. For the convenience of the non-Hindi- speaking states English is also used officially.

6. Linguistic unity. Linguists are of the view that the Indian languages and their literatures have much more in common than their apparent or outward differences. All the Indian languages are phonetic in nature and have a more or less common structure and a surprisingly large common vocabulary. There is not much difference in the scripts of many of these languages.

Question 6.
Write an essay on problem of population increase in India and also enlighten the solution to this problem.
Answer:India’s population is growing rapidly, and creating some problems.

Low standard of living. Indian people have low standard of living as compared that of Europeans. About 48% people live below poverty line. They do not have full meals. It results in low production capacity.
Deforestation. The forests are cleared recklessly to meet the growing needs. It has resulted in problems of soil erosion, floods, pollution and loss of forest-wealth.
Lack of pastures. India has only 4% land under pastimes. If this land is used for other purposes, it will result in shortage of fodder for cattle.
Pressure on Land. Land is a limited source and cannot be increased. It is leading to pressure of population on land. It will decrease the productivity of the land.
Lack of minerals. Industries are developed to meet the growing needs of people. So more minerals are used. These reserves will exhaust soon.
Environment. Population growth has an adverse effect on environment. Clear water and air is a problem. Oxygen is also decreasing.

Solutions:

Family planning should be adopted,
People should be explained significance of small families by films, songs, plays,
Illiteracy should be abolished so that people should understand harms of growing population,
Female education should be increased, marriageable age of girls be increased.

Question 7.
Study critically the efforts being made Tor the expansion of Education in India.
Answer:
Education. One of the basic inputs in human resource development is education. Literacy and numeracy form the foundation on which superstructure of education is built.
1. At the time of independence only 14% of the people were literate. It meant that they could at least read and write names. By 2011 it has slowly risen to 65.58%. In absolute terms the number of the literates has grown to 550 million from 60 million. It is about 11 fold growth. But it is pertinent to note that the number of the illiterate persons has also increased.

2. Our constitution directed the Government to provide education for all children upto the age of fourteen. This was a big task because the bulk of the population was distributed over half a million villages. These villages are separated by considerable distance from one another. Priority was, therefore, given to set up schools in almost every village. As a result there are now half a million primary school in place of two lakhs in 1951. Similarly the middle schools also increased by as much as ten times. Earlier there was one middle school for every 15 primary schools. Now it stands for every four primary schools.

3. Although there has been a marked increase in the number of children getting into formal schools. One of the worries is that out of every 100 children in class I, only 40 manage to complete class V and 25 reach class VIII. Thus three fourths of the pupils drop out on their way.

4. We have also made progress in increasing the number of secondary schools, universities, industrial training as well as other institutions. Still educational facilities are not available to all because of fast growing population.

IV. Show the following on the map of India:

Short Answer Type Questions

Question 1.
State three reasons for the uneven distribution of population in India.
Answer:

The distribution of population in India is unequal. According to 2011 census, the total population of India is 121 crore and the density of population is 382 persons per sq. kilometre. The density of population varies according to relief, climate and the agricultural productivity of the land. The density of population depends on the amount of rainfall.

Factors favouring high density:
(0 Sufficient rainfall
(ii) Fertile river valleys and deltas.
(iii) 2 to 3 crops of rice in a year.
(iv) Irrigation facilities.
(iv) Healthy climate.
(vi) Rich in mineral and power resources.

Factors for moderate density:

Agriculture is not developed due to thin and rocky soils.
Rainfall is uncertain.
Means of transportation are not developed.
Some areas have high density of population due to irrigation, lava, soils and mineral resources.

(b) Rajasthan Desert. Rajasthan has a density of 200 persons per sq. kilometre.

The hilly nature of the land.
Dense forests.
Low rainfall
Poor econoufic development.
Absence of minerals.
Lack of irrigation and agriculture.
Cold climate.

Question 2.
Throw light on some important aspects of population of India.
Answer:

India is one of the selected countries where population concentration is found.
After independence, population of India has increased 4 times.
India has an average population of 3 crores for each state.
U.P. has the highest population in India.
Average density of population is 382 persons per sq. km.
West Bengal has the highest density of population.

Question 3.
How is the growth of population a problem for India ?
Answer:
After independence, the land-area has been fixed in India but the population has increased manifold. The growth of population is 1.7 per-cent. It is a great problem to provide basic amenities to such a huge population. It is not easy to provide the facilities of education, hospitals and other facilities to all. We shall have to increase the transport and communication facilities also. We shall have to cultivate quality in our population.

Question 4.
State the adverse effects of rapid growth of population in India.
Answer:
The rapid growth of population has posed many socio-economic problems in different countries. The main problems are:

Food problem. Growth of the population has led to shortage of foodgrains in many areas.
Agricultural production has increased due to new technology, yet many countries have to import agricultural products.
Housing problem. Housing conditions are poor in over-populated countries. People live in slum areas. Skyscrapers are being built in many Metropolitan towns.
Unemployment. Rapid increase in population leads to unemployment. Migration of people from over-populated rural areas has added to Unemployment.
Low standard of living. Per capita income is low in overcrowded areas so living conditions are poor. People do not afford to have basic necessities of life. Population explosion leads to poverty and a poor standard of living.
Dependent population. A large percentage of young people become dependent on a small working population.
Social problems. Many social problems arise due to overcrowding. Poor health and bad sanitary conditions lead to epidemics.

Question 5.
Why is the occupational structure of India lop sided?
Answer:
Two thirds of our population still lives on agriculture. Only 10% of the working population is engaged in industry. The rest one fourth of population is in the tertiary or service sector. This makes clear that a small proportion of our population is engaged in secondary sector of economy. The secondary sector includes manufacturing by which we can increase our national income by producing useful products. So there are not more people employed in manufacturing. So our occupational structure is lop sided.

Question 6.
Why are the Northern plains densely populated?
Answer:

Factors favouring high density:

Sufficient rainfall
Fertile river valleys and deltas.
2 to 3 crops of rice in a year.
Irrigation facilities.

Low rainfall
Poor econoufic development.
Absence of minerals.
Lack of irrigation and agriculture.
Cold climate.

Question 7.
Name three sparsely populated areas of India. Give reasons.
Answer:
The rapid growth of population has posed many socio-economic problems in different countries. The main problems are:

Food problem. Growth of population has led to shortage of foodgrains in many areas.
Agricultural production has increased due to new technology, yet many countries have to import agricultural products.
Housing problem. Housing conditions are poor in over-populated countries. People live in slum areas. Skyscrapers are being built in many Metropolitan towns.
Unemployment. Rapid increase in population leads to unemployment. Migration of people from over-populated rural areas has added to Unemployment.
Low standard of living. Per capita income is low in overcrowded areas so living conditions are poor. People do not afford to have basic necessities of life. Population explosion leads to poverty and a poor standard of living.
Dependent population. A large percentage of young people become dependent on a small working population.
Social problems. Many social problems arise due to overcrowding. Poor health and bad sanitary conditions lead to epidemics.

Question 8.
Explain the following with reference to population of India.
(a) census
(b) density of population
(c) growth of population
(d) death rate.
Answer:
(a) Census. After every ten years, the Government arranges the counting of all persons of the country. It is called census. Some social and economic data is also collected. The last census in India was held in 2011. According to this census, the total population of India was 121 crores.

(b) Density of Population. Density of population means the average number of persons living in a unit sq. area. It is shown per sq. km. According to 2011 census, density of population in India was 382 persons per km2.

(c) Growth of Population. People, sometimes, migrate from one area to another due to epidemics or droughts or in search of employment. It increases or decreases the population of an area. In the area to which people migrate population increases. It is known as growth of population or decrease in population.

(d) Death Rate. Death rate means the number of deaths per 1000 persons.

Question 9.
What do you mean by Dependency Ratio? Why is it high in India? Give two reasons.
Answer:
The proportion between productive and dependent population is dependency ratio. Children and old people are dependent population. India has a joint family system. Therefore children and old people get livelihood automatically. Illiteracy has also increased it. Orthodox views increase this ratio.

Question 10.
What is major mistake done by Indian planning? What are its effects?
Answer:
The most important and pathetic mistake of the Indian Planning according to Dr. Sen is the development of institution, on the basis of caste etc. In Delhi, he said, “several buildings do not have public toilets, which is important for every building. As compare to other such as China, Pakistan, Bangladesh have expanded education system and health care facilities. But this is a pathetic condition in India.

Question 11.
Distinguish between distribution of population and density of population.
Answer:
Population in India is not evenly distributed. Many factors are responsible for this:

Fertility of the soil. The states in which there is a large fertile area the density of population is high. U.P. and Bihar are such states.
Amount of rainfall. The density of population is higher in regions of abundant rain. In northern India the amount of rainfall goes on decreasing from east to west. The density of population also goes on decreasing in the same direction.
Climate. Wherever the climate is congenial the density of population will be high. In Assam even though there is abundant rainfall but the density of population is low because the climate is unhealthy. The malaria is always there is an epidemic form.
Developed means of transportation. With development of means of transportation the business makes rapid progress and the density of population increases. The reason for high density of population in U.P., Bihar and West Bengal is the development of means of transportation.
Industrial development. At places where the factories are located the density of population also increases. The reason is that people like to live in those areas where industrial development takes place. They can carry on their business more easily in such areas and they have better chances of earning more money. That is why the density of population is high in Delhi, Mumbai and Kolkata.

Question 12.
Why is the conservation of resources necessary?
Answer:
Man depends upon the environment to meet his needs. He uses water, land, soil, vegetation, etc. to satisfy his needs. Man is using these resources at such an alarming rate that there will be serious shortage of these resources in the near future. Natural resources are of limited supply. So, conservation of resources is essential for the survival of man.

To some people conservation means that the available resources should not be used. These should be held back. But conservation of resources means a careful and rational utilization of resources. These resources should be used intelligently for the welfare of mankind. It means a careful control and management of resources so that these may be usd for the benefit of future generations also. These should be preserved from reckless exploitation and wanton destruction. These resources should not be wasted in a short time. The resources should be maintained in a healthy condition for their use as to achieve a high standard of living for mankind.

Question 13.
Why is low density of population found in Rajasthan and Arunachal Pradesh?
Answer:
In some areas, it is difficult to get means of livelihood. These have a harsh climate. The soils are sandy or hilly. Agriculture is not possible. There is absence of irrigation and the production is low. Industries can not be developed in such areas. Therefore low density of population is found in Rajasthan and Arunachal Pradesh.

Question 14.
The people are important to develop the economy and society. Give three facts.
Answer:

People use available resources.
They create a social and cultural environment..
Intelligent and hard working people make the real man power.

Question 15.
Define birth rate. What is its function with reference to population?
Answer:
Birth rate is the number of live births per 1000 persons in a year. It is a component of growth of population; because birth rate is always higher than death rate. The population increases when birth rate is higher tMn death rate.

Question 16.
Define death rate. What is its function with reference to population?
Answer:
Death rate is the number of deaths per thousand persons in a year. It is a component of growth of population. Due to declining death rate, there is a rapid growth of population in India. When death rate is more than birth rate, the population growth is negative.

Long Answer Type Question

Question 1.
List factors influencing the distribution of population.
Answer:
The following factors influence the distribution of population:
1. Fertility of the soil. The states in which there is a large fertile area, the density of population is high. U.P. and Bihar are such states.

2. Amount of rainfall. The density of population is higher in regions of abundant rain. In. northern India, the amount of rainfall goes on decreasing from east to west. The density of population also goes on decreasing in the same direction.

3. Climate: Wherever the climate is congenial, the density of population will be high. In Assa even though there is abundant rainfall but the density of population is low because the climate is unhealthy. The malaria is always in an epidemic form.

4. Developed means of transporUition. With development of mans of transportation the business makes rapid progress and the density of population increases. The reason for high density of population in Ui., Biliar and West Bengal is the development of means of trahsportation.

5. Industrial development. At places whëre the faetones are located, thë density’ of population also increases. The reason is that people like to live in those areas where industrial development takes place. They can carry on tliei1 bushis mo easily in such areas, and they have better chances of earning more money. That iš why the density of population is high in Delhi, Mumbai and Kolkata.

Question 1.
Read the below questions carefully and answer the given questions.
Due to this vastness, India is called an Indian sub-continent. The sub-continent is a large and independent region. The boundaries of whose terrain are drawn by various natural features which distinguish it from the surrounding areas. India also crosses the Agil, Muzigh, Kunlun, and Karakoram, Hindukush and Jaskar mountain range from Tibet across the Himalayas in the north, from Pak, Jal Damru in the south and Gulf of Mannar from Sri Lanka, east. In the direction, Arakan separates Yoma from Myanmar (Burma) and in the western direction from the vast Dhar desert, Pakistan. Due to such a vast area of India many cultural, economic, and social variations are found. But despite this unity is found in climate, culture, etc. in the country.
(a) Why is India called the sub-continent?
Answer:
India is given the status of sub-continent due to its expansion and position. The sub-continent is a vast and independent landmass whose boundaries are formed by different topography. These topographies separate it from its surrounding areas. Agile across the Himalayas in the north of India. The mountain ranges of Mugtgh, Kunlun, Karakoram, Hindukush, etc. distinguish it from the north-western parts of Asia. In the South, the Pak strait of central and the gulf of Mannar separate it from Sri Lanka. Formerly Arakan Yoma separates it form Myanmar. The Thar Desert separates it from a very large part of Pakistan. Despite this, we cannot call present day India a sub¬continent. The Indian sub-continent is formed by the combination of undivided India, Nepal, Bhutan and Bangladesh.

(b) Which elements contribute to maintaining unity in the diversity of the country?
Answer:
India is a country of diversity. Yet a distinct unity appears in our society. The main elements that provide unity to Indian society are the following:
1. Monsoon Season. The monsoon winds make most of the rainfall in summer. This affects the agriculture of the country as well as other business. Monsoon winds make the power supply reliable by raining the mountainous regions. Infact, monsoon rainfall is the basis of the entire country’s economy.

2. Religious Culture. There are two things in favor of religious culture. One is that religious places have united the people of the country in one sutra. Secondly, religious saints have instilled a sense of brotherhood through their teachings. People from all parts of the country come and worship at Tirupati, Jagannathpuri, Amamath, Ajmer, Harimandir Sahib, Patna, Hemkunt Sahib and other pilgrimage places. The saints have also tried to create religious harmony.

3. Language and Art. Almost all the northern India. Vedas were propogated in Sanskrit language. Urdu was born in the middle age of this language. English is the contact language and Hindi is the national language. Together, these have provided an opportunity to understand each other closely. Siinlarly, folk songs and folk arts have also created an opportunity for people to express similar feelings.

4. Traffic and means of communication. Railways and roads have played an important role in bringing people of different areas closer. The means of communication like Doordarshan and newspapers have also connected the national stream by giving the national thinking of the people.

5. Migration. Many people from villages have started coming to the cities. Despite their racial differences, they have come to understand each other and thus they have come closer to each other. The truth is that many natural and cultural elements have given unity to our country.

Question 2.
The vast northern plains along the Himalayas provide habitat and livelihood to 40% of the country’s population. Their fortile soil, suitable climate, flat surface have contributed significantly in the spread and development of rivers, canals, roads, railways and cities and in the development of agriculture. Therefore, this plain region has the distinction of being the granary of the country. These plains have built a special kind of civilization and society since the Aryans. People from all over the country consider Ganga to be a holy river and the Rishikesh, Haridwar, Mathura, Prayag, Ayodhya, Kanshi etc. places in its valley have been the center of attraction for sufi saints and religious people living in different parts of the country. Later in these plains, great men like Sikh Guru, Mahatma Buddha, Mahavir Jain were born and different religious were established. Its deep impact can be seen in the Himalayan mountains and also in South India.
(a) Name the major landforms created by the rivers in the vast plains of the north.
Answer:
The landforms formed by the rivers in the northern plains are alluvial fins, alluvial cones, sepentine turns, hilly staircases, natural dams and floodplains.

(b) Describe the huge northern plains contribute to the development of the country.
Answer:
The Himalayan regions have the following contribution to the development of the country.

Rain. The monsoon winds from the Indian Ocean hit the Himalayan mountains and rain heavily. Thus, it donates rain to the northern plain. There is enough rainfall in this ground.
Useful Rivers. All the major rivers flowing in northern India originate from the Himalayan mountains like Ganga, Yamuna, Sutlej, Brahmaputra, etc. These rivers flow throughout the year. In the dry season, Himalayan ice burns these rivers.
Fruit and Tea. The slopes of the Himalayas are very useful for tea cultivation. Apart from these, fruits are also grown on the mountain slopes.
Useful Wood. Dense forests are found on the Himalayan Mountains. These forests are our wealth. Many industries in India depend on the wood derived from them. This wood is also used in building works.
Good Pastures. Beautiful and green pastures are found on the Himalayas. Animals are fed in them.
Mineral Substances. Many types of mineral substances are found in these mountains.

Question 3.
The word ‘climate’ or ‘wind water’ refers to the long-term seasonal conditions in a place, in which the temperature of that place is the amount of water in the air flowing from there. These conditions are mainly determined by important elements such as surface variation of the place, distance from the coastline and distance from the equator. It has a profound effect on human and human activities. India is a vast country. Its vast sin-face units, the peninsular position and the tropic of cancer passing through it have a profound effect on its climate. Due to the largest surface variations of temperature, rainfall, winds and clouds etc.
(a) Describe the (two) elements affecting the climate of India.
Answer:
The main elements influencing the climate of India are :

Distance from the equator.
Surface Pattern.
Air pressure system
Seasonal winds and
Proximity to Indian Ocean.

(b) What are the regional variations of Indian climate?
Answer:
The regional variations of Indian climate are as follows:
1. In winter the temperature reaches – 45°C in the Kargil regions of the Himalayan mountain but at the same time it is more than 20°C in Chennai (Madras) metropolis in Tamil Nadu. Similarly in summer the western direction of the Aravali mountains is crossed 50° centigrade, while the Srinagar is less than 20° centigrade. There is a temperature of 204 centimeters in Srinagar.

2. The annual rainfall is located in the mountain range of Mawsymaram, 1141 cm. Annual rainfall in Jaisalmer is less than 10 cm. in the year.

3. In Barner and Jaisalmer are carved clouds, but the whole year is the same as the same year throughout the year.

4. Due to the effect of the sea in Mumbai and other coastal cities, the temperature ramains almost same of the year. In contrast, the National area is found to be huge difference in the cold and hot temperature in the area and surrounding areas.

Question 4.
The economy, the relief and social development is deeply influenced the economic progress. In the social development, the area can be applied to the development of economic progress there. Indian agriculture, almost completely dependent on. agriculture (aggregated). In which development of the monsoon has given significant contributions to providing a major and strong basis. Monsoon is called a pivotal point of the country. Apart from agriculture, the entire production is dependent oh agricultural production, If monsoon rainfall is in appropirate amount, the agricultural production increases. But because of the failure of monsoon, the crops dried. The country goes dry and the grains are reduced in the stores.
(a) Discuss the important features of the monsoon.
Answer:
In India rainfall is mainly in July to September. This is the period of southwest monsoons blowing from sea to land. There are three important features of the monsoon rainfall.

Erratic. Rainfall is not reliable in India. It is not necessary that rain continues to be same. Due to this erratic situation of rain, the situation of starvation and famine is arranged. This erratic situation of rainfall is more in the inner parts of the country and in Rajasthan.
Uneven Distribution. There is uneven distribution of rainfall in India. Western slopes of western ghats and Meghalaya or in the hills of Assam. There is more than 250 cm. rainfall. In contrast Rajasthan, West Gujarat, North Kashmir etc., the rainfall is less than 25 cm.
Uncertainty. The amount of rainfall in India is not certain. Sometimes monsoon winds reached before time, It rains a lot. But sometimes the rainfall is low or sometimes ends up before a time. As a result the situation of drying is generated in the country.

(b) Why the Indian Economy (budget) is called gambling of monsoon winds?
Answer:
Indian monsoon is a gambling of monsoon winds. This sentence reveals that the advancement of India’s economy depends on that how much appropriate time of any year, distribution and quantity.
If the rain comes on time and its quantity is also suitable, a good crop of agriculture can be expected.

For example-crops are good due to good monsoon, so three things happen.

Fair raw materials available for factories. The industry-related factors of cotton, jute, oil seeds etc. are flourishing.
When the agriculture and industires are strengthened from good monsoon, the
productivity increases. On one hand, the export is promoted. On the other hand international trade is flourishing. Wealth grows in the country and people’s standard of living improves.
Due to good monsoon, there is an increase in water in the rivers, the water level of the dams rises high. Where this water helps in the production of hydropower, the irrigation system improves. This creates a stir in economic activities in the country. There is no doubt that today due to the advancement of science, we can grow a good crop even in the absence of monsoon, but we have to think about whether all farmers can benefit from lack of rainfall or unequal distribution of rainfall. A good monsoon affects every section and every region of the country. If the monsoon is suitable, the country’s economic development is assured. Therefore, it is fair to call the Indian economy a gamble of monsoon winds.

Question 5.
Agriculture has an important role in the Indian economy. The agricultural sector employs about two-thirds of the country’s workforce. The region derives 29.0 percent of the total national income and agricultural products a1 so have an important place in foreign exports. Many products of agriculture are used as raw materials in our factories. Due to the progress in the field of agriculture, the achievement of food grains per person, which was 395 grams in the 1950’s has increased to 510 grams per person per day in 1991.
India also ranks fourth in the world in the use of chemical fertilizers. The area under pulses in our country is the highest in the world. In the field of cotton products, India is the first country in the world, where the first efforts were made to produce improved varieties of cotton. The country has made significant achievements in the preparation of prawn fish and pest culture technological development.
(a) What percentage of land is cultivable in India?
Answer:
51% of the land in India is cultivable.

(b) Why is agriculture called the mainstay of the Indian economy?
Answer:
Agriculture is the mainstay of the Indian economy. Even though agriculture now contributes only 33.7% of the total national production, its importance is no less.

Agriculture sustains 2/3 of our population.
The agriculture sector provides employment to about two-thirds of the country’s workers.
Most of the industries get raw materials from agriculture. The truth is that the place of industries is being built on the foundation of agriculture.

Question 6.
A decline in per capita achievement of pulses in Punjab and other parts of the country is a matter of concern. It seems that the wave of ‘Green Revolution’, which has revolutionized the production of wheat and rice in the country has not made any special contribution in increasing the production of pulses. Actually, if it is said that there is harm then there will be no wrong. Because in the years following the Green Revolution, the area of pulses has been diverted to a large number of high yielding crops like wheat and rice. This has happened especially on a large scale in commercially agricultural states like Punjab.
(a) In Punjab, what kind of changes has occurred in the pulses production area after Green revolution.
Answer:
After the green revolution, the area of pulses production decreased from 9.3 lakh hectares to 9.5 thousand hectare.

(b) What are the main reasons for the decline in the production of pulses?
Answer:
The production of pulses has decreased in the last decades. The main reasons for this are as follows :

The area with pulses has been subjected to crops like wheat and rice, which produce more after the Green Revolution.
Some areas have been subjected to canals, roads, and other development projects due to development work.
The growing area of pulses has also declined due to increasing land demand for
housing of the growing population.

Question 7.
Our country is also considered very rich in terms of mineral wealth. It is estimated that the country accounts for one fourth of the total iron ore reserves in the world. There are also huge deposits of manganese, a major mineral used in the iron and steel industry. There are also abundant reserves of coal, limestone, bauxite and mica in the country. But non-ferrous minerals such as zinc, lead, copper and gold are in very limited quantities. The sulfur reserves in the country are almost nil, while sulfur is the mainstay of modern chemical industry. We also have plenty of water power resources and nuclear minerals. Their use as a power tool is increasing rapidly due to their power efficiency and very little tampering with the environment. For this reason, solar energy is also being used as a power tool. Solar energy is the priceless power store of God. Its use will increase rapidly as a source of power in the future.
(a) What is the contribution of minerals to the national economy?
Answer:
Minerals have great importance in the national economy. The following facts will make it clear.

The industrial development of the country depends mainly on minerals. Iron and coal are the basis of the machine age. We have one-fourth of the world’s iron ore deposits. There are also huge reserves of coal in India.
State governments get income from mining operations and provide employment to millions of people.
Coal, petroleum, natural gas etc. are important sources of mineral energy.
Equipment made from minerals helps in the growth of agriculture.

(b) Why is solar energy called the source of future energy?
Answer:
Coal and mineral oil are exhaustive resources. There will come a day when the people of the world will not get enough energy from them. Their stores must have been exhausted. Unlike then, sun energy is a never-ending means. This gives a tremendous amount of energy. When the reserves of coal and mineral oil are exhausted, then power will be obtained and we will be able to do it easily with our domestic work and plants.

Question 8.
All the trees, thorn bushes, plants and grasses etc. are included in the natural vegetation which grow without human intervention. Before starting its study, it is necessary to know the related words like Flora, Vegetation and Forests. Different species of plants that grow in a certain time and in a certain area are included in the flora, shrubs, plants, grass etc. that grow at a place in a certain environment are called vegetation. Whereas a large area surrounded by dense and adjacent trees, plants, thorn bushes etc. is called forest. The term jungle is mostly used by environmental scientists and forest guards and geographers. Each type of developed vegetation has to go through a long life cycle by creating a delicate balance with its environment, which depends on the quality of its mutual cohesion and ability to adapt. The entire flora found in our country is not local, but 4Q% of it belongs to foreign castes which are called Boreal and Paleo-Tropical species.
(a) Name the foreign castes and quantities in the country.
Answer:

The foreign vegetation species present in the country are called as Boreal and Paleo-Tropical.
The amount of foreign vegetation in India is 40%.

(b) Write briefly on the autumn or monsoon vegetables.
Answer:
The vegetation that leaves its leaves before the start of summer to prevent further evaporation is called the autumn or monsoon vegetation. This vegetation can be divided into two sub-parts which are and wet based on rainfall.

Autumn Forest. This type of vegetation is found in four big areas, where the annual rainfall varies from 100 to 200 cm. Trees are less dense in these areas but their height reaches 30 metres. Sal, Sheesham, Teak, Chandan, Jamun, Amltas, Haldu, Ebony, Mulberry are the major trees of these forests.
Dry Deciduous Vegetation. This type of vegetation is found in areas with rainfall less than 50 to 100 cm. Its long strip starts from Punjab and extends to the adjoining areas of the southern plateau. Kelkar, Babool, Banyan, Haldu are the main trees here.

Question 9.
In our country, along with the diversity of vegetation, there is a large variety of fauna. In fact there is a deep interconnection between the two. About 76 thousand species of fauna are found in the country. 2500 species of fish are found in the fresh and salt water of the country. Similarly, there are 2000 species of birds. 400 species of snakes are found in India. Apart from this, amphibians, reptiles, mammals and small insects and worms are also found. Mammals have majestic elephants with majestic chicks. It is an organism of equatorial tropical forests. In our country, it is found in the forests of Assam, Kerala and Karnataka. It rains heavily and the forests are also very dense. In contrast camels and wild asses are found in very hot and dry deserts. Camel Thar is the common animal of the desert, while wild plants are found only in the Rann of Kuchh. They have a horned rhinoceros in the opposite direction. They live in marshy areas in northern parts of Assam and West Bengal. Among Indian animals, the Indian bison, the Indian buffalo are particularly notable.
(a) Name the animals found in the Himalayas.
Answer:
In the Himalayas, wild sheep, mountain goat, a long horned wild goat and tapir etc, are found, while pandas and Himatendua animals are found in high mountain

(b) What are the works being done to look after the animals in the country?
Answer:
Indian Wildlife Protection Act was enacted in 1972. Under this, 1,50,000 square kilometers of area (2.7% of the country and 12 percent of the total forest area) in various parts of the country were declared as national parks and wildlife sancturies.

Near Extinction Special attention has been paid to wildlife.
The work of counting animals and birds has been started at the National level. At present there are 16 tiger reserves in different parts of the country.

A special scheme for rhinoceros conservation is being carried out in Assam. The truth is that till now 18 Biosphere Reserves have been established in the country.
Under the scheme, the first life reservation area was created in Nilgiri. Protection of every animal is mandatory under this scheme. This natural heritage is for future generations.

Question 10.
A combined mixture of light, loose and unstructured rocky shreds and fine-grained bacteria found on the earth’s surface is called soil which has the power to give rise to plants. Deposition of this mixture is found in deep layers ranging from 15-30 cm to several metres. But the soil scientist is divided into three layers called A, B and C respectively, depending on the depth and quantity of soil colour, texture, size of particles etc. Due to the high quantity of humus in ‘A’ Horizon soils, they begin to turn black. But due to being situated in the zone of leaching on this layer, the minerals dissolve and go down and the colour starts to turn dark black. The colour of sub-layer with ‘B’ Horizon under this layer is brown due to the mineral matter leaking from the top layer. But the aihount of humus in it decreases. Below this layer, a layer of ‘C’ Horizon soil is found in which the substances separated from the above rocks do not have any special change and later go to the main base rock. The colour of this sub-rocky surface is grey or light brown,
(a) Describe the definition of soil.
Answer:
The combined mixture of light, loose and unstructured rock crust (shell powder) and fine granules found on the earth’s surface is called soil.

(b) What is the contribution of primary rocks in the birth of soil?
Answer:
The primary rocks in the country consist of lofty rocks of the northern plains or lava-formed rocks of the plateau. They contain various types of minerals. Therefore, they make good soil. The colour, formation, texture, etc. of the soil formed by the primary rocks depends on how long the rocks are being affected and by what kind of climate. In a state like West Bengal, the spil is highly developed due to the effects of chemical reactions in the climate and humus. But in dry area like Rajasthan, due to lack of vegetation, soil fertility decreases. Likewise, soil erosion is more in areas with high rainfall and high winds. Fertility decreases as a result.

Question 11.
In today’s knowledge and information-based world, the important contribution of human resources is being realized in national construction and development much better than before. Today all the countries of the world, especially the developing countries, are paying more attention to the development of human resources than before. Children can you think why is this ? In the countries of South Korea, Taiwan, Hong Kong, Singapore, Malaysia etc., known as ‘Asian Tigers’, the rapid development of economic development is being attributed to the huge investment made in the development of human resources in the last few decades. In human resource development, not only the parameters like education, technical skills, health and nutrition but also human-ethics-ideas, civilization- culture, species and nation-pride should be included. Only then will human resource development becQme a complete ideology.
(a) What is the most valuable resource of a country?
Answer:
Intellectually and physically healthy citizens.

(b) Why is it important to study the population structure of the country?
Answer:
There are many reasons why it is necessary to know the population structure of a country.

Various characteristics of the population of any country for social and economic planning such as the age structure of the population, gender structure, business structure etc. data is required.
Different components of the population structure are closely related to the economic development of the country. While the population structure components are affected by economic development from another, they are also unable to remain untouched by the impact of progress and level of economic development. For example, if the percentage of children and old people in the age structure of a country’s population is very high, then the country will have to spend more and more financial resources on basic facilities like education and health. On the other hand, the rate of economic development of the country is accelerated due to the higher proportion of working-age groups in the age structure.

Question 12.
The study of the regional pattern of population distribution provides the basis for understanding all demographic components of the population. For this reason, it is very important to understand the regional pattern of distribution of population. Here first we must also clarify the difference between population distribution and population density. Population distribution is related to place and density is related to ratio. Population distribution implies that what is the regional pattern of population in any part of the country, that is, the population pattern is nucleated or agglomerated in one place. On the other hand in density, which is related to population size and area, attention is given to the ratio of man and area. The history of human settlements in India is very old. That is why the population resides in every part of the country which is the sum of human. habitation. Yet the distribution of population is greatly affected by the fertility* of the land. As India is an agricultural country, the pattern of population distribution depends on agricultural productivity. For this reason, in states where the productivity of agriculture is high, the concentration of population is equally high. Apart from agricultural productivity, the variation of physical factors, industrial development and cultural elements also contribute significantly in influencing the population distribution pattern of India.
(a) Name the largest and least populous states of the country.
Answer:
The most populous state in the country is Uttar Pradesh and the least state is Sikkim.

(b) Describe the format giving the salient features of the regional pattern of population distribution in the country?
Answer:
The regional pattern of population distribution in India and its important features are as follows:
1. The distribution of population in India is very uneven. Population is very dense in river valleys and seaside plains, but the population is very sparse in the mountainous desert and scarcity areas. Only 3% of the population lives on 16 percent of the country’s land in the hilly regions of the north, while 40 percent of the population lives on 18 percent of the country’s land in the northern plains. In Rajasthan, 6 percent of the population lives on only 6 percent of the country’s land.

2. Majority of the population is settled in rural areas. About 71% of the total population of the country resides in rural areas, about 29% in cities. Large cities have a large population of urban population. Two thirds of the total urban population lives in first-tier cities with population of one lakh or more.

3. The concentration of minority communities in thei country is in the most sensitive and important outer border areas. For example, the Sikhs in Punjab and the Muslims in Jammu and Kashmir are in abundance near the Indo-Pak border in north western India. Similarly there is a gathering of people of Christianity along the borders of China and Burma (Myanmar) in the northeast. Many social, economic and political difficulties arise from such distribution.

4. On the one hand, the population is dense in the coastal plains and valleys of the rivers. On the other hand, the population in the mountainous, plateau and desert parts is sparse. -This distribution resembles a demographic divide.

Wheat can be grown in areas of moderate rainfall. 50 to 75 centimeters rainfall is quite suitable for its cultivation. The rain should be well distributed
The soil should be fertile. Loamy soil is very suitable for wheat cultivation.
The land should be even for the convenience of irrigation.

Production. India occupies fourth position as a producer of wheat in the world.
Green revolution has brought many changes. In 1960-61 wheat production was 1.6 crore tonnes. In 2011-12 it increased to 8.5 crore tonnes.

Wheat Producing States. Although wheat is cultivated in almost every part of the country except the southern part of the Indian peninsula, it is essentially a crop of North India. Uttar Pradesh produces highest quantity of wheat in India. Punjab occupies the second position as a producer of wheat in India. Haryana is also an important producer of wheat.
PSEB 10th Class SST Solutions Geography Chapter 5 Land Utilization and Agriculture 2

(a) Forests are helpful in maintaining ecological balance and natural Eco-system.
(b) Forests supply timber and fuel. It is used for making furniture, packing boxes, boats etc. and is used for buildings.
(c) Soft wood is used for preparing wood-pulp which has a large demand for paper
industry.
(d) We obtain lac, cane, gum, medicinal herbs from forests.
(e) We get fodder for cattle from forests.

Question 10.
Why is Indian agriculture known as ‘Subsistence Agriculture’?
Answer:
Most of land holdings in India are of small size. Large amount of capital and labour is applied on small farms, but economic benefit is small. Small farmers have to hire agricultural implements and tubewell water for irrigation. They have to purchase costly fertilizers from the market. It results in a small net savings. Therefore Indian agriculture is called Subsistence Agriculture.

Question 11.
Why some people call green revolution as ‘wheat revolution’?
Or
May green revolution be termed as wheat revolution only. How?
Answer:
Total production of wheat in 1960-61 was 1 crore 10 lakh tonnes. But due to green revolution it increased five times in 1993-94. Due to the enormous increase in wheat production, sometimes it is called wheat revolution,

Question 12.
Explain the efforts made for the development of animal wealth.
Answer:
Many attempts have been made by Central govt, and state govts, for the development of livestock farming in India.

Special attempts have been made to improve their breed, to protect them from different diseases, to control their diseases; and provide market facilities. At least one veterinary hospital has been started in each block. At village level, the health centres for livestock have been opened. In 1992-93, such health centres were more than 22,000. Besides this, 26 cattle injection centres in public and private sectors had been opened.

Question 13.
What are the reasons that are responsible for the increase in land use under non-agricultural purposes?
Answer:
There are two reasons for the increasing use of land for non-agricultural purposes growing population and economic development. The urban and rural areas are increasing in size due to growing population. Due to increase in economic development large area is being used for canals, roads, industries and irrigation projects.

Question 14.
Write in brief about the importance of forests.
Answer:
Forests are important in our daily life in the following ways:

These maintain ecological balance.
Trees absorb carbon dioxide and control the increase in temperature.
Forests are the home of wild animals. These protect them.
Forests increase the rainfall and droughts do not occur,
Forests preserve water resources and control floods in rivers.

Question 15.
What effect incurred after independence on the requirement of foodgrains per head?
Answer:
After independence, many steps have been taken to develop agriculture. As a result, the production of foodgrains has increased. From 1950-51 to 1994-95, production of rice has increased four times and production of wheat has increased ten times. It has affected food for persons. In 1950 the availability of foodgrains was 395 grams per person per day. In 2000 it had increased to 458 grams per person per day.

Question 18.
What are the reasons of small land holdings in India? How these effect Indian agriculture?
Answer:
50% land holdings are less than one hectare in size. The main reason for it is law of inheritance. After the death of the father, the land is equally divided among the sons. Therefore size of the land holding is small due to increasing pressure of population on land. Due to small holdings the farmer cannot use machinery and the advanced methods of irrigation. As a result, he has to hire water and machinery. Therefore, net saving is less and the farmer is becoming poorer day by day.

Question 17.
Name the main paddy producing states.
Answer:
West Bengal was the largest rice producing state of India with a production of 1.39 crore tonnes in 2000-01. Other main producers are U.P., Andhra Pradesh and Tamil Nadu, Bihar. Punjab and Orissa. Each state produces more than 60 lakhs tonnes of rice. Besides this, M.P., Assam, Karnataka, Maharashtra and Haryana are other large producers of rice.

Question 18.
What are the causes for high per hectare yield of wheat in Punjab?
Answer:
Punjab is the second largest producer of wheat in India. Punjab ranks first in yield per hectare and its contribution towards national store of wheat is due to

Wheat is cultivated on a large scale in Punjab because it is a commercial crop in Punjab.
Better irrigation facilities are available.
The yield per hectare is high.
The yield per hectare has increased due to mechanised agriculture.

Question 19.
What are the causes of decrease in area under pulses cultivation?
Answer:
The production of pulses and oil seeds are still low due to the following reasons:

The areas under cultivation of pulses and oil seeds is small. Pulses are grown on an area of 2.3 crore hectares.
There is absence of irrigation.
The yield per hectare is low. The green revolution has not affected it,
The rate of growth of population is more than the rate of production of these crops.

Question 20.
Write down the benefits of Dairy Industry.
Answer:
Dairy farming includes rearing of cattle to get milk and milk products. It is a part of agriculture. It has the following advantages:

It provides employment in drought areas.
It provides additional income to farmer.
It provides nutrients in diet by increasing the production of milk.

Question 21.
Why production of pulses and oil-seeds is still low?
Answer:
The production of pulses and oil seeds is lower and does not meet our needs. This is due to:

Low production of Pulses. The production of pulses was 1.3 crore tonnes in 1960-61. It was 1.4 crore tonnes in 1993-94. Unfortunately, the yield of pulses per person has reduced to one half. This is due to the decrease in area under pulses. Much area has been brought under cultivation of rice and wheat. There has been decreasing of 34 lakh hectares under pulses during the last thirty years.
Low production of Oil-seeds. The position of oil-seeds is opposite to-that of pulses. There has been increase in area under oilseeds as well as production of oilseeds. In 1960-61 area under oilseeds was 1.4 crore hectares. It increased to 2.23 crore hectares in 2000-01. The production increased two fold but still there is shortage of oilseeds. The demand is increasing by 5% annually and 2% growth of population is making the problem more severe.

Question 22.
What are the main problems of Indian agriculture?
Answer:
The following are the agricultural problems of India:

There is a great soil erosion because the area under forests and pastures is small.
Most of the soils are saline. More than one lakh hectares is affected by this in Ferozepur district.
Most of the farmers are illiterate and are unable to practise crop rotation.
Cultivated land is decreasing due to the increasing use of land for non-agriculturai purposes.
The size of the land holding is small, uneconomic and there is small net saving. Because the farmers have to hire the costly machinery and costly fertilizer
Fall in ground water and loss of fertility are other problems.

Question 23.
Explain the changes that have occurred rapidly in the diversification of crop rotation after Green Revolution.
Answer:
Rapid changes have taken in crop-rotation after Green Revolution. This is due to the increase in productivity in areas affected by Green Revolution (Punjab, Haryana and H.P.). Agricultural productivity has decreased in the traditional rice producing areas of the East. Besides this, the agricultural development, in Green revolution affected areas, has become stagnant. To meet these problems, the farmers have adopted new systems of crop rotation in different areas. For example, Punjab has adopted a Wheat-Rice rotation system, and U.P. has taken to Wheat-Sugarcane crop-rotation system.

Question 24.
What are the indications that depict that Indian agriculture is advancing towards commercial agriculture leaving behind the subsistence type of agriculture?
Answer:
Subsistence farming means the raising of crops for the local consumption according to needs of the farmer and his family. In commercial farming the surplus is sold in the market. The following factors have been responsible for transforming Indian agriculture from subsistence to commercial farming:

The Govt, has passed legislative measures to abolish the Zamindari system.
Chakbandi has consolidated scattered land holdings of the farmers to make it of economic size.
Cooperative movement has helped the farmers to collectively tackle their problems of credit and marketing.
National banks provide loans to farmers on relatively easy terms.
The Agricultural Price Commission fixes the minimum support prices for various crops. The farmers are not compelled to sell their products at low prices,

Question 25.
What efforts have been made by Government of India for the development of Agriculture?
Answer:
The Central and State governments have taken the following five important steps for the progress of agriculture in India:

Consolidation. The government under the five year plans have consolidated the small holdings into big blocks in order to mechanize the agriculture.
Supply of quality seeds. The government has undertaken to supply seeds of good quality to the farmer so that agricultural output is increased.
Supply of fertilizers. The government, therefore, has started supplying chemical fertilizers to the farmers. Many factories have been set up to meet the demand of chemical fertilizers.
Modern means of agriculture. In order to increase the agricultural output new machines are being used for agriculture.
Means of irrigation. Many multipurpose projects have been completed. Dams have been built across the rivers and the water thus stored is used for irrigation. Bhakra-Nangal project and Damodar Valley Corporation are examples of this type of projects.

III. Answer the following questions subjectively:

Question 1.
Explain, in detail, the problems being faced by the Indian Agriculture.
Answer:
The main problems of Indian Agriculture are as under:

The most important problem of Indian Agriculture is the pressure of population on land. About 65% workers depend upon agriculture for their livelihood; but earn only 29% of the National income.
Most of the land holdings are small and unequally distributed. These are uneconomic.
The area under forests and pastures is low. Therefore soil erosion has an adverse effect on soil fertility.
Most of the farmers are illiterate. They cannot practise crop-rotation. So the natural fertility of the soil decreases. So intensive agriculture affects the fertility of the soil.
Irrigation has become a problem in India. There is necessity of extending irrigation facilities in Rajasthan, Maharashtra, M.P., Karnataka, etc.; but due to over-irrigation in Punjab the problems of water logging and saline soils have been created.
The capital investment in Agriculture is decreasing. In 1980-81, the capital investment was Rs. 1769 crores, but in 1990-91 it decreased to Rs. 100 crores. After that this capital investment is on increase.
Marginal development has taken place in development of better seeds.
Diversification of crops and slow growth is also a problem.
The fact is that Govt, has a strict control on agriculture and prices. Farmers cannot be provided adequate facilities like industries.

Question 2.
Write an explanatory essay on the Green Revolution of India.
Answer:
Green Revolution is a new strategy used to increase the production of foodgrains in the country. A revolution has taken place in the agricultural methods and technology. This revolution is known as Green Revolution. It includes the use of better quality seeds, high yielding varieties, chemical fertilizers, agricultural machinery and to provide irrigation facilities. It has led to a complete modernisation of Indian Agriculture.

This strategy was introduced to do away with food shortage and import of foodgrains. In 1961 seven districts were selected for this programme. In Punjab, Ludhiana was one of these districts. Green Revolution affected the whole of Punjab. Punjab became the bread basket of India. Yield per hectare of wheat rose to 3531 kg. in 1985-86. But in India it was 2132 kg. In fact, Green Revolution helped to increase production on less land.

Question 3.
Explain in detail about the cultivation of Paddy in India.
Answer:
Rice. Rice is the leading agricultural crop of India. It is the staple food of 2/3rd of her population. Suitable geographical environment for its cultivation, its production and trade are described ahead:
PSEB 10th Class SST Solutions Geography Chapter 5 Land Utilization and Agriculture 1
Geographical conditions. The geographical conditions suitable for rice cultivation are the following:

Rice is the product of moist tropical region. It requires high temperature. The temperature should not be more than 25°C. At the harvest times especially, the temperature should be high.
Rice requires great amount of water. A rainfall between 130 and 200 cms is suitable for it. A good crop of rice mainly depends on the Monsoon. Deficiency in rainfall can be made up by irrigation.
Very fertile soil is needed for rice cultivation. Clay and delta soils are most suitable for it.
Rice requires a lot of manual labour. Therefore, cheap labour should be available for its cultivation. Therefore rice is grown in densely populated areas.

Rice Producing Areas. India stands next only to China in the production of rice. In India, West Bengal produces largest quantity of rice. Tamil Nadu and Jharkhand are second and third producers of rice respectively. Rice is also grown in Karnataka, Madhya Pradesh, Maharashtra, Chhattisgarh, Kerala, Assam, Sikkim, Himachal Pradesh, Punjab and Haryana. In 2011-12 rice was grown in 4.3 crore hectares of land in India and the total output of rice was 9.5 crore tonnes.

Question 4.

PSEB 10th Class SST Solutions Geography Chapter 5 Land Utilization and Agriculture 2
The states of Bihar, Madhya Pradesh, Rajasthan, Gujarat, Jammu and Kashmir, Himachal Pradesh and Maharashtra also grow some wheat.

Question 5.
Write about the cultivation of pulses in India.
Answer:
The production of pulses has not shown any marked increase in India. India is still the largest producer of the pulses. Main pulses include Grams, Arhar, Masur, Mung and Peas. It is grown in dry areas all over the country in both the Kharif and Rabi season.

The area under pulses has not increased because a large area was cultivated for wheat and rice after green revolution. In 1960-61 pulses were cultivated in an area of 2.6 crore hectares. But in 2000-01 it reduced to 2.23 crore hectares showing a decrease of 30 lakh hectares during the last 34 years.

The production of pulses was 1.3 crore tonnes in 1960-61 and increased to 2.5 crore tonnes in 2010-11. With better seeds, the production of pulses can be increased.

Question 6.
Highlight the causes that led to decrease in area under oilseeds after Green Revolution. What steps have been taken by the government to increase the cultivation of oilseeds?
Answer:
Oilseeds are grown in combination with other crops to increase the soil fertility. It acts as pivot in crop rotation. After green revolution the area under oilseeds had decreased. In 1975-76 the area under oilseeds was 3.2 lakh hectares. In 1991 it decreased to 1.0 lakh hectares.
Steps taken. The Government is providing better seeds to increase oilseeds production. Good prices have been offered for oilseeds so that farmers should take interest in its cultivation.

Question 7.
Write a comprehensive essay on the cotton production in our country.
Answer:
Cotton is an important fibre crop. The cotton yarn is used for manufacturing cloth. Cotton plantation in India has been done since ancient times (during Indus civilisation). The Babylonians called it ‘Sandhu’ and Greeks called it ‘Sindo’.

Geographical conditions. Given below are the physical requirements of cotton cultivation:

High temperature is needed for cultivation of cotton crop. Average temperature should be between 30°C and 35°C.
A moderate amount of rainfall is required for cultivation of cotton. Cotton can be easily grown in area with 50 to 100 cms of rainfall. Irrigation is used in dry areas.
During the growing period of the cotton plants the relative humidity should be high. At the time of picking the weather should be dry.
Cotton can be grown in many types of soils but loamy soil is ideal for its growth. In India it is mostly grown in the black cotton soil region of Gujarat and Maharashtra. A special feature of black soil is that it can retain moisture for a long period and the need for irrigation is minimised. In Punjab and Haryana cotton is grown in alluvial soil.
Most of the activities connected with cotton cultivation require manual labour. Therefore large amount of cheap labour is essential.

Sowing and harvesting periods. In most parts of India cotton is a summer crop. It is sown from April to June and harvested in the months of September and October. In Gujarat it is sown in the month of June and harvested in October. In Tamil Nadu cotton is sown in September and harvested in the month of March.

Production. India is the fourth biggest producer of cotton in the world. India produces about 700 lakh bales of cotton, each bale weighing 170 kilograms. In 2011-12 the area under cotton cultivation was 86 lakh hectares.

State-wise distribution. Maharashtra state is the biggest producer of cotton in India and produces about 26.3 lakh bales of cotton. The other important cotton producing states of India are Haryana, Madhya Pradesh, Karnataka. Punjab, Gujarat (second largest producer), Rajasthan, Tamil Nadu and Andhra Pradesh. Most of the cotton grown in India is of short staple type but the cultivation of long staple American and Egyptian cotton is on the increase.

Question 8.
Explain the main features of Horticulture in India.
Answer:
Horticulture means cultivation of vegetables, flowers and fruit. Its main characteristics are:

India ranks second in the world in the production of fruit and vegetables. The production of fruit was 3.9 crore tonnes and the production of vegetables was 6.5 crore tonnes.
Different types of fruit, vegetables and flowers are grown due to diverse climatic conditions. Tea and coffee on hill slopes and coconut in coastal areas are grown.
India ranks first in the world in the production of bananas, mangoes, coconuts and cashewnuts. India is a large producer of oranges, apples, potatoes, tomatoes, onions and peanuts.
The exports of these products is 25% of the total exports of India.
Floriculture has increased due to demand in foreign countries. 200 units have been selected to export flowers.
Jammu and Kashmir, Himachal Pradesh states lead in the production of apples, Maharashtra in the production of oranges and bananas, Andhra Pradesh and Tamil Nadu in the production of mangoes and Kerala in the production of cashewnuts.

The production of fruits and vegetables has rapidly increased in Punjab. In 2000-01, the production was 8 lakh tonnes. Hoshiarpur, Ferozpur, Amritsar and Faridkot are the leading districts. 26.6 thousand hectares of land is under kinoo gardens and orange plantation.

Short Answer Type Questions

Question 1.
Which is the most satisfying feature of land use pattern in India? What are its main features?
Answer:
The most satisfying feature of land use in India is that net sown area is increasing. During last 3 decades 2.2 crore hectares has been added to it. Today net sown area is 16.2 crore hectares and it is about 47.7% of total area.

Main Features:

The area under forests is low. It is only 22.7% of total area. But for a self-reliant economy and proper ecological balance, one third of the land should be under forests.
The area under pastures is low.

Question 2.
Distinguish between fallow land and wasteland. What are two advantages of fallow land to farmers?
Answer:
Fallow lands are lands which are not cultivated annually for crops. Only one crop is grown on these-lands during two or three years. After getting one crop, it is left vacant to maintain its fertility. Its use depends on timely monsoonal rain. Wasteland is a land which is not used for cultivation. It includes arid, rocky and sandy land.

Advantages of Fallow Land:

Fallow lands regain their lost fertility.
Agricultural production is increased due to increase in productivity of land.

Question 3.
Distinguish between subsistence farming and commercial farming giving one example from each.
Answer:
Subsistence farming is the type of agriculture in which crops are grown for local consumption to meet the needs of the family. On the opposite, commercial farming meets the demand of market. In commercial farming, one crop is grown and cultivation is done on large farms using scientific techniques. Subsistence farming includes wheat farming while tea plantations are a type of commercial farming.

Punjab has fertile land deposited by alluvial soils. These loamy soils are best suited for wheat.
Cyclonic rainfall, which occurs over a long period, is well suited for wheat.

Question 5.
Why is the rice cultivation increasing in Punjab? Give four reasons.
Answer:
Increase in rice cultivation is due to these reasons:

Intensive farming is practised in Punjab with the use of better seeds and fertilizers.

Long Answer Type Questions

Question 1.
What are the major characteristics of land use pattern in India?
Answer:
Land use pattern. Land is a limited resource. Attempts are made to make the maximum use of land. India has total geographical area of 32.8 crore hectares. Out of it 92.2% area is used.

Main characteristics of land use are as under:
(а) Net sown area. About 51% of total land (16.3 crore hectares) is net sown area. This vast area shows the importance of agriculture in India. It includes 1.3% land under fruits and 5% under fallow land.

(b) Fallow land. About 5% land (2.2 crore hectares) is left as fallow land and is cultivated after two or three years. Fallow land has decreased due to use of fertilizers and manures.

(c) Forests. About 22.7% of land (6.7 crore hectares) is under forests. The actual area under forests is 4.6 crore hectares. According to scientific norms, l/3rd of area should be under forests.

(d) Pastures. About 4% land is under pastures. Still India has the largest number of cattle in the world. Cattle are reared on fodder crops.

(e) Other uses. Land under permanent grassland, cultivable waste, and not available for cultivation amounts to about 22% of total land. It includes wasteland also.
Moreover the demand for human settlements is increasing due to growing population.

Question 2.
Describe the geographical conditions of growth, areas and production of tea in India. Also, discuss its International Trade.
Answer:
India is the leading producer of tea in the world. Tea plantations were started by the British for their own benefit. Now Indians are the owners of these plantations. About 10 lakh persons are engaged in Tea farming directly and same number of persons get employment indirectly. It is labour-intensive industry.
(а) Geographical conditions. The following geographical, conditions are suitable for cultivation of tea:

Abundant rainfall (150 cms) is necessary for the growth of tea plants.
Tea requires high temperature. An average temperature of 20°C to 30°C is suitable for its proper growth.
The relative humidity should be high.
The water should not stagnate in the roots of the plant.-Therefore tea is mostly grown on the hilly slopes.
Tea requires fertile soil.
Cheap labour is very essential for tea plantation as the picking of leaves requires human labour.

(b) Tea producing states. Assam is the biggest producer of tea in India. West Bengal is the second largest producer of tea in India. Tea is grown in Darjeeling, Jalpaiguri, Nilgiri hills. Tea is also grown in Bihar, Tamil Nadu, Tripura, U.P., Himachal Pradesh, Kerala and Karnataka.

(c) Production. In 1950-51, tea estates covered an area of 3,14,000 hectares. In 2000-01 the area under tea estates raised to 4,00,000 hectares. In 1950-51 total production of tea was .2,75,000 tonnes. In 2011-12, it rose to 8,00,000 tonnes. It amounts to one half of the world production.

(d) Trade. In 2010-11, India exported 2.03 lakh tonnes of tea valued at Rs. 1976 crores. Sri Lanka is a competitor of India as regards exports of tea. Kenya is a new tea-exporter. Tea consumption is increasing in India. So tea export is decreasing.

Question 3.
What are the main causes of backwardness of the Indian agriculture? Suggest remedies for its improvement.
Answer:
Causes of backwardness. The causes of backwardness of the Indian agriculture are as under:

Dependence on rain. The Indian farmer depends on rain for irrigation. Only 23% of the cultivated land has irrigation facilities.
Dearth of Nitrogen in the soil. Indian soil is poor in nitrogen. The land has been cultivated for thousands of years continuously and has, thus, affected the fertility of the soil.
Poor labour. The Indian farmers are weak in health and they cannot provide the required amount of labor for agriculture.
Subdivision of holdings. In India the land is equally distributed amongst all the sons after the death of the father. As a result the size of fields goes on decreasing and this affects the production.
Primitive methods of agriculture. The Indian farmer is still following the
primitive methods of agriculture. Hence agriculture in India has suffered a setback.
Non-utilization of good seeds. Indian farmers are poor and do not use seeds of good quality. This lowers production.
Poverty. Money is needed for agriculture but the farmers are poor.
Weak cattle. Indian farmer cultivates his land with the help of bullocks but most of the bullocks in India are not of good breed. They are very weak and are thus unable to undertake agricultural activities properly.
Illiteracy. The Indian farmer is illiterate. He finds it difficult to adopt new methods of agriculture.

Suggestions for improvement of agriculture:

Co-operative farming. Co-operative farming should be introduced. This will increase the size of the fields and modem methods of agriculture would easily be adopted.
Improvement in irrigation. In order to bring improvement in agriculture, the irrigation facilities should also be improved.
Intensive farming. The farmers should adopt intensive farming. This brings more return from a smaller area.
Good seeds and fertilizers. The government should arrange to supply quality seeds and fertilizers to the farmers at reasonable rates.
Use of new agricultural implements. There can be a lot of improvement in agriculture if modern agricultural implements are used by the farmers. The government should give financial aid to farmers for the purchase of such implements.
