Longitudes are angular distances of a place from the Prime Meridian, whereas latitudes are angular distances of a place from the equator.

Question 7.
Why longitudes are called Meridians of Longitude? Into how many Meridians do we divide the Earth or Globe?
Answer:
Longitudes are called Meridians of Longitude because they are drawn through the Prime Meridian. We divide the Earth or Globe into 360° meridians.

Answer:
The circle of equator is the largest circle of Globe.

Question 9.
What is the difference between Parallels of Latitude and Meridians of Longitude?
Answer:

Parallels of Latitude	Meridians of Longitude
1. Parallels of latitude are imaginary circles drawn parallel to the equator.	1. Meridians of longitude are imaginary lines running from North to South.

Longitudes help us in knowing the east-west distance of a place.
They help us in calculating the local time of a place.

Question 11.
Which lines help us to divide the Earth into Heat Zones? Give reasons why there are Heat Zones.
Answer:
Latitudes help us to divide the earth into Heat Zones. Heat Zones are there because of the following reasons :
1. The rays of the sun which are vertical, occupy less space but intensity of heating is very high and the rays of the sun which are slanting, occupy more space but intensity of heating is low.

2. The shape of the earth is spherical. The central, the bulging part of the earth receives maximum heat of the sun and as we go away from the central part towards the poles, the heat reduces.

Question 12.
What is the difference between Local Time and Indian Standard Time?
Answer:
1. Local Time. Local time is the time reckoned by the noon sun at a given place. At any place a watch can he adjusted to read 12 O’ clock when the sun is at the highest point in the sky or when it is mid day. The time shown by such a watch will give the local time for that place. All the places, on a given meridian of longitude, have the same local time.

2. Indian Standard Time. In a particular country, local time of a particular or rather a central place is adopted as the uniform time for the whole country. It is called the standard time of that country or that area. In India, the local time of 8214 ° E Longitude is used as the standard time for the whole country.

Question 3.
What are the shortcomings of a globe?
Answer:
A globe has some limitations :

It is not easy to carry globes.
It is not useful for studying an area of a country.
Only one hemisphere can be studied from a globe.
Distances cannot be measured on a spherical globe.
Globes do not show details.

Question 4.
Into how many Heat Zones can tile earth be divided? Explain each zone.
Answer:
The earth can be divided into three Heat Zones. They are Torrid Zone, Temperate Zone and Frigid Zone.
1. Torrid Zone: It lies between the Tropic of Cancer and the Tropic of Capricorn. It is the hottest zone of the world. The noon sun shines vertically over this part of the earth.

2. Temperate Zone: It lies between the Tropic of Cancer and the Arctic Circle in the Northern Fig. Heat Zones of Earth
Hemisphere and between the Tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere. The sun is never overhead in this zone. It is neither very hot in summer nor very cold in winter. It is, therefore, called the Temperate Zone.

3. Frigid Zone: It lies between the Arctic Circle and the North Pole in the Northern Hemisphere and the Antarctic Circle and the South Pole in the Southern Hemisphere.

Question 5.
Describe the important Parallels of Latitude.
Answer:
The Equator, the Tropic of Cancer, the Tropic of Capricorn, the Arctic Circle, and the Antarctic Circle is the important Parallels of Latitude.

The Equator: The equator is the most important parallel of latitude. It divides the earth into two equal parts. These parts are the Northern Hemisphere and the Southern Hemisphere. It is the largest possible circle that can be drawn around the earth.
The Tropic of Cancer: It lies in the Northern Hemisphere at 23°30′ latitude. It is an angular distance of 2314° N from the equator.
The Tropic of Capricorn: It is also an imaginary circle measuring the angular distance of 23/4° to the south from the central point of the equator.
The Arctic Circle: It is the parallel of latitude that lies at a distance of 6614° North of the equator.
The Antarctic Circle: It lies in the Southern Hemisphere and is at 66!4° South to the equator.

Question 6.
How do longitudes help us in calculating time?
Answer:
Longitude and Time.

Longitudes help us to calculate time.
It takes 24 hours for the earth to complete one rotation.
This means in 24 hours the Earth completes 360°.
Hence, it takes about 4 minutes for crossing one degree of longitude.
This means each place has a different time of Sunrise and Sunset.
Places East of the Greenwich Meridian experience day or sunrise earlier than the places lying west of this Meridian.

In other words, time is ahead in the east than that in the west, at the rate of 4 minutes per degree of longitude.

Long Answer Type Questions

Question 1.
Describe the Northern Plains of India.
Answer:
The Northern Plains of India are a region of a vast alluvial plain. This region extends from Punjab-Haryana Plains to Assam Valley. 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 sqvkm.

It can be divided into the following parts :
1. The Punjab-Haryana Plains. These plains owe their origin to the depositional work of the Sutlej, the Beas and the Ravi rivers. This is a uniform and flat plain and is formed by the Indus and its five tributaries. Due to creation of international border between India and Pakistan in 1947, greater part of it went to Pakistan. To the other side, due to the rise of surface near Delhi, the Yamuna has started flowing towards east. Delhi and its surrounding area work as a water divide between the Ganga and Indus River Drainage System.

The interfluves formed on the basis of river boundaries can be divided into four sub-divisions :

Bari Doab or Majha: Area between the Ravi and the Beas is known as Bari Doab or the Majha plain in Punjab.
Bist Doab: Area between the Beas and the Sutlej is called Bist Doab or the Doaba plain in Punjab.
Malwa: Plain area spreading from the Satluj to the Ghaggar is called Malwa Plain in Punjab.
Plain of Haryana: Area from the Ghaggar to the Yamuna is known as Plain of Haryana.

2. The Thar Desert Plain. The drier and the flat area extending from the southern parts of Punjab and Haryana to the Rann of Kuchchh of Gujarat is known as the Thar Desert. The Aravali mountain ranges form its eastern boundary. Due to the scarcity of rain, whole of the region has become sand-duned. In the Barmer District sand-dunes are 50 to 100 metres high. In whole of this dry region the action of wind is very fast. Westward along the Aravalis, there are fertile plains, called Rohi. There are many salt lakes like Samber lake.

3. The Ganga Plain. This plain is spread over the states of Uttar Pradesh and Bihar, extending from the Yamuna in the west to the international boundary of Bangladesh in east and the Shiwaliks in the north. This vast and fertile plain is important from the historic, agricultural and dense population point of view. The main rivers of this plain are the Ganga, the Yamuna, the Ramganga, the Chambal, the Betwa, the Kali and the Pandu.

4. The Brahmputra Plain. These plains are also called the Assam plains. The Brahmputra, Sesari, Dibang and Lohit are the rivers of this plain.

Question 2.
Explain the Indian islands.
Answer:
India has almost a total of 250 islands. On the basis of their location, these islands are divided into two main sub-divisions :

Offshore Islands
Onshore Islands.

1. Offshore Islands.: These islands are further divided into two :
(a) The Island Group of the Arabian Sea. Formed with the deposit of coral reefs in the South-eastern Arabian Sea these islands are known as Lakshadweep. They are 25 in number. The whole group has three major parts. The northern part is named as Amindive, the middle as Laccadive and the southern as Minicoy.

(b) The Island Group of the Bay of Bengal. Some of these islands are made up by volcanic eruption and some are the raised parts of the peaks of sub-merged hills.

These islands also have three main parts :

Andaman Island Group,
Nicobar,
Other Adjoining Islands.

There are about 120 islands in the Andaman Group of Islands. Indira Point island of Nicobar is the southernmost point of India.

2. Onshore Islands. In these islands near the delta of Ganges, small islands such as Wheeler, New Moor, etc. are found. Some islands are found near the coast of Tamil Nadu. Big islands like Diu are situated near the coast of Gujarat.

In Khambat and Rann of Kutchchh, islands of various sizes are found.

SST Guide for Class 6 PSEB How Maps Help Us Textbook Questions and Answers

I. Answer the following questions in brief:

Question 1.
What is a map?
Answer:
A map is the representation of the earth or a portion of the earth, drawn to a scale on a flat surface.

Question 2.
What is a Globe?
Answer:
A Globe is a true representation of the earth or a model of the earth.

Question 3.
Write the difference between a Map and a Globe.
Answer:

A Map	A Globe
1. A map is the representation of the earth’s surface or a part of it on a flat surface according to a scale.	1. A globe is the true model of the earth. It shows the earth in its true shape. It is a correct replica of the round shape of the earth.
2. A map is convenient to handle. It is very easy to carry a map from one place to the other.	2. A globe is not convenient to handle. We find it difficult to carry a Globe from one place to the other.
3. Every feature can be shown in detail in a map.	3. Every feature cannot be shown in detail on a globe.

Question 4.
Why were maps made? Give their importance.
Answer:
Undoubtedly, a Globe is a true model of the earth. But globes occupy a lot of space and they are difficult to be carried everywhere. A need was felt to carry something handy, something that can be carried in one’s pocket and also included in a book. So maps were made.

Importance of Maps:

Maps help us in learning the different aspects of Geography.
They show us the position of the places in relation to latitudes and longitudes that are drawn on the map.
They help us in locating the distance from one place to another, time and location.
They help us in locating the trade centres, routes, slope of the land, rivers, etc.
They are used by the government for administrative purposes.
They guide the travellers and also are useful for the army.

Question 5.
Enlist the different types of maps.
Answer:
The different types of maps are:

Physical maps,
Historical maps,
Distributional maps,
Topographical maps,
Atlas maps,
Wall maps.

Question 6.
What are the pillars of maps and why?
Answer:
Distance, direction and conventional signs are the pillars of maps. These are also known as the most essential components of maps. These are the pillars of maps because, without knowledge of them, we won’t be able to read the map correctly.

Question 7.
What do you understand by the conventional symbols?
Answer:
It is not possible to show on the map the actual shape of features such as a building, a well or a tree. So symbols are used to represent various features in maps. With their help, it is easier and quicker to read and understand the maps. They also make the map clearer and easier to be read. As there has been a common agreement all over the world regarding the use of these symbols, they are called conventional symbols.

Question 8.
Make a chart of the conventional symbols.
Answer:

Question 9.
In coloured maps, with which colour we show mountains, uplands, plains, rivers, forest and snow-covered hills.
Answer:

Physical Features	Colour
1. Mountains	Brown
2. Uplands	Yellow
3. Plains	Green
4. Rivers	Blue
5. Forest	Green
6. Snow covered Hills	White

Question 10.
What is the use of directions in the maps?
Answer:
In the upper right-hand margin of the maps we see an arrow. The tip of the arrow is marked with the letter ‘N’
It means that the arrow is pointing northwards. The arrow is, therefore, called the North Line.

Direction

Question 11.
How does scale of the map help us to study the maps?
Answer:
Scale of the map is a measuring line with the help of which correct distance between various points on a map can be measured. In a scale, there is always a proportion between the dimensions of the map and the actual areas they represent on the earth. It can be a millimetre, a centimetre or an inch to represent a kilometre, a hundred kilometre or even still larger distances.

Short Answer Type Questions

Question 1.
Distinguish between Morning and Evening.
Answer:

Morning	Evening
1. It is the time of sunrise.	1. It is the time of sunset.
2. The rays of the sun appear on the horizon in the east.	2. The rays of the sun appear to be descending to the horizon in the west.
3. It is the time between the day break and noon.	3. It is the time between the noon and sunset.

Question 2.
Distinguish between Rotation and Revolution.
Answer:
The distinction between rotation and revolution is as under :

Rotation	Revolution
1. The spinning of the Earth on its axis is called rotation.	1. Annual motion of the Earth round the Sun is called revolution.
2. The time of rotation is about 24 hours.	2. The time of revolution is 365 days 6 hours.
3. Days and nights follow each other in regular succession in all parts of the Earth due to rotation.	3. The change of season takes place because of the revolution of the Earth.

Question 3.
Why do people experience more heat during noon than in the morning or evening?
Answer:
The rays of the sun are vertical at noon and slanting in the morning and evening. The great amount of heat is received by the earth when the sun’s rays fall vertical over it. Hence, people experience more heat during noon. Since the sun’s rays fall slanting in the morning and evening, they scatter over the greater area and hence they are comparatively cool.

Question 4.
Why do we have longer days and shorter nights in the Northern Hemisphere during summers?
Answer:
The earth’s axis is inclined by 23 1/2° to one side. Due to .this inclination, the Northern Hemisphere remains inclined towards the sun during one half of the year. Hence, the days are fonger and nights are shorter. In contrast, the Southern Hemisphere is always away from the sun during this half of the year.

Question 5.
What is a leap year? Why does a leap year have an extra day than an ordinary year?
Answer:
A leap year is one which has 366 days. It comes after a cycle of four years.

The earth moves around the sun and takes 365 days and 6 hours to make a complete round of it. We take 365 days in a year and ignore six hours. But these six hours make a day in four years. Hence, one day is added to every fourth year. Thus, every fourth year is called a leap year because it has 366 days. The extra day is added to the month of February. In an ordinary year, February has 28 days while in a leap year, it has 29 days.

Question 6.
How are days and nights caused?
Answer:
Days and nights are caused due to rotation. The earth rotates on its axis from West to East. When it rotates, one half of the earth turns towards light and has therefore day. The other half turns away

Day and Night

from the sun and remains in darkness and has night. During 24 hours, every part of the earth comes in turn before the sun and then goes into darkness. Therefore, the position of day and night keeps on changing. When it is day in one hemisphere, it is night in the other. The circle that divides the day from night on the globe is called circle of illumination (circle of light). This circle does not coincide with the inclined axis of the earth.

Question 7.
Make Difference between Summer and Winter Solstice.
Answer:

Summer Solstice	Winter Solstice
1. Summer solstice occurs on 22nd June in Northern hemisphere.	1. Winter solstice occurs on 22nd December in the Northern hemisphere.
2. The whole Northern hemisphere experiences more heat and light.	2. Northern hemisphere exper¬iences less heat and light.
3. It is summer in the Northern hemisphere.	3. It is winter in the Northern hemisphere.
4. Days are longer, nights are shorter.	4. Days are shorter, nights are longer.
5. Reverse conditions prevail in the Southern hemisphere.	5. Reverse conditions prevail in the Southern hemisphere.

Question 8.
What would happen if the Earth did not rotate?
Answer:
If the earth did not rotate :

The portion before the sun would have remained the same and continued to experience day regularly.
On the other hand the portion of the Earth away from the sun would have experienced night continuously.
Life would have not been possible on the Earth in such a situation.

Long Answer Type Questions

Question 1.
(a) Define Rotation.
Answer:
Rotation: The spinning of the earth on its axis from West to East is called rotation.

(b) What is the period of rotation?
Answer:
The earth takes about 24 hours (23 hours 56 minutes 4 seconds) to complete one rotation. It is also known as daily motion of the earth.

Rotation causes days and nights.
All bodies like sun, moon, planets appear to move from East to West.
Tides occur regularly twice a day.
Winds and ocean currents change their directions.
The four main directions (North, South, East, West) can.be determined with the help of rotation.
We get a measure of time. A day consists of 24 hours-one complete rotation.
The different times of a day like sunrise, noon, sunset, midnight can be determined due to rotation.

Question 2.
(a) What is a revolution?
Answer:
Revolution: The spinning of the earth around the sun, along an elliptical orbit from West to East is known as revolution.

(b) What is period of revolution?
Answer:
It takes a year or 36514 days to complete one revolution. Hence it is also known as annual motion of the earth. The earth’s axis is always inclined at a fixed angle of 66/4° to the plane of the ecliptic,

(c) What are aphelion and perihelion?
Answer:
When the earth is farthest from the sun (152 million kms) it is aphelion. When the earth is nearest the sun (147 million km) it is perihelion,

(d) What are its effects?
Answer:
Effects:

Due to revolution, the lengths of days and nights vary at a place at different times of the year.
Revolution causes a change of seasons.
It helps in the location of Tropic of Cancer and Tropic of Capricorn due to the fact that the sun’s rays fall vertical here.
Altitude of the mid-day sun changes.
It gives us a measure of time for one year.
Poles have days and nights of 6 months duration.
It determines the distribution of solar energy on the earth.

Rotation and Revolution

Question 3.
(a) How many seasons are there in a year?
Answer:
Normally, four seasons are experienced during a year- spring, summer, autumn, and winter.

(b) What are the causes of seasons?
Answer:
The change of seasons is due to the following reasons :

Rotations of the earth.
The inclination of the earth’s axis at 66 1/2° to the plane of the orbit.
The axis remains always in the same direction.
Revolution of the earth.

(c) Describe the conditions in each position.
Answer:
Due to the four seasons, the earth keeps on changing its position at different times of the year or during one revolution. These are seasonal positions. Each position of the earth with relation to the sun changes and explains different seasons.

Seasonal Positions :
1. Position on 21 June:

North pole is inclined towards the sun and the South pole is tilted away from the sun.
The larger part of the northern hemisphere is in daylight, while the larger part of the southern hemisphere is in darkness.
Days are longer than nights in northern hemisphere while nights are longer in the southern hemisphere.
The Sun shines vertical on the Tropic of Cancer (2314°N), but the southern hemisphere has slanting rays.
Hence the Northern hemisphere, with vertical rays and longer days has summer season. The southern hemisphere with slanting rays and shorter days has winter season. This position is also called the Summer Solstice. 21st June is the longest day and the shortest night in the northern hemisphere.

2. Position on 22 December: This position of the earth comes six months after the first position.

The South pole is inclined towards the sun and the north pole turns away from the soil.
The major part of the southern hemisphere is in light, while the major part of the northern hemisphere is in darkness.
Days are shorter than nights in the northern hemisphere while days are longer in the southern hemisphere.
The sun shines vertically on the Tropic of Capricorn (2314 °S) and the northern hemisphere gets slanting rays.
Hence the southern hemisphere with perpendicular rays and longer days has the summer season. This is the season of the southern summer and of the northern winter. It is also called the Winter Solstice. December 22 is the longest day and shortest night in the southern hemisphere.

3. Positions of 21st March, 23rd September:

In these positions, the sun shines vertically on the equator.
The circle of light passage through the poles dividing the globe into equal parts.
Neither of the poles is inclined towards the sun.
Every parallel has one half in darkness and the other half in light, with the result, the days and nights are equal all over the world.
Both the hemispheres have similar seasons. It is autumn on 23rd September in the northern hemisphere and spring in the southern hemisphere.
It is spring on 21st March in the northern hemisphere and autumn in the southern hemisphere. These positions are called Equinoxes (meaning equal nights).
