Question 5.
Who is the Executive head of a state?
Answer:
The Governor is the Executive head of a state.

II. Answer the following Questions in 50-60 words

Question 1.
Write in short the functions of the Governor.
Answer:
Although the Constitution gives vast powers to the Governor, yet he is not the real head of the state. He exercises all the powers on the advice of the Chief Minister and the Council of Ministers. If the Governor disagrees with the ministers, he places himself in an awkward position. They would resign and the Governor would be compelled to find an alternative ministry. The Council of Ministers is responsible to the Legislative Assembly and not to the Governor.

But it must be noted that the Governor is something more than a mere nominal head or rubber stamp. He has the powers to advise, warn and encourage the Council of Ministers. He functions as the agent of the Centre. He acts as a link between the Centre and the State and is the watchdog of the Constitution.

He has certain functions which he can perform at his discretion.

  • He recommends to the President to declare an emergency in the State.
  • He becomes the real ruler of the State after the emergency is declared in the State.
  • He can appoint a person of his choice as the Chief Minister in case no party in the State Legislative Assembly wins majority of seats.
  • He can send back the bills passed by the State Legislature for reconsideration.
  • He can reserve certain bills for the approval of the President.

Question 2.
Write about the powers and functions of the Chief Minister.
Answer:
The Chief Minister is the real executive head of the State government. He selects his ministers. The Governor must give approval to his list of ministers. The Chief Minister distributes portfolios among the ministers. He reorganizes the Council of Ministers from time to time. He can appoint new ministers and remove the inefficient ones. The Chief Minister is the link between the Governor and the Ministers. He is also the chief advisor to the Governor. The Chief Minister is the leader of the Gis party and also the leader of the State Legislature. The people of the State look upto him for his guidance and development of the State.

Thus, we see that the Chief Minister is the most important figure in the State. He enjoys the same position in the State as the Prime Minister at the Centre. So long as he enjoys the support of majority in the Vidhan Sabha, he has complete control over the State Government. He is the pivot round which the whole Council of Ministers and the total administration revolves.

Question 3.
Give in brief the election procedure of Legislative Assembly or Legislative Council.
Answer:
The State Legislative may consist of one or two chambers or houses. The lower and the more popular house is called the Vidhan Sabha or Legislative Assembly. It shall not consist of more than 500 and not less than 60 members. The upper chamber is called Vidhan Parishad or Legislative Council. The minimum number of members of a Vidhan Parishad shall be forty and the maximum number should not be more than one-third of the total membership of the Legislative Assembly of that state. 5/6 members of Legislative Council are elected by teachers, members of local bodies, MLAs and Graduates. The rest 1/6 members are nominated by the Governor.

Question 4.
Which civil officials (Bureaucracy) run the state administration?
Answer:
In the State there are education, irrigation, transportation, health, sanitation, etc. departments. While ministers are the chiefs of these departments but actually civil servants run these departments who are known as secretaries. They are appointed by Union Public Service Commission or State Public Service Commission. The secretary is the chief advisor of his concerned minister. In the state there is one head of all these secretaries known as Chief Secretary of the State. The office of the secretary is known as the secretariat.

II. Answer the following questions in 50-60 words :

Question 1.
Write short note on the emergence of democracy.
Answer:
The beginning of democracy was in Athens, city of Ancient Greece. The democracy there is almost 2500 years old. It is said that in Athens, the general public would hold meetings many times in a year. Here, the decisions were taken directly by the people for running the administration. Such democracy is known as direct democracy. At that time it was possible because the population was less and people could gather at one place and take decisions. Direct democracy was possible also because the women, the foreigners and the slaves had no right to participate in the administration. But today direct democracy is not possible.

Question 2.

Answer:
First of all, it was established in Greece in Athens city. The democracy there is almost 2500 years old. The people of Athens would gather many times in a single year and hold meetings. In these meetings they would take decisions about how to run the management of the state.

PSEB 7th Class Social Science Solutions Chapter 18 Democracy and Equality

Question 3.
Write name of four types of democracy on the basis of classification.
Answer:
1. Presidential type of Government: In this, the President is directly elected by the people. He is the real ruler of the state. So, the President and the ministers are not from a single political party. Such type of presidential form of government is in America. The President here is more powerful than the Indian President.

2. Parliamentary type of Government: In this, the Parliament is the most powerful organ. The President is just for the name only. The real power is in the hands of Prime Minister. All members of the council of ministers are taken from the Parliament or legislatures. So, there remains a co-ordination between legislatures and executives.

3. Unitary type of Government: In it, there is division of powers between the state and the centre. But centre is more powerful than the states. The Indian Constitution is federal in nature. But in times of emergency, the powers of central government increase.

4. Federal Government: Here the Constitution is written and rigid. There is division of power among centre and the states. Every state has its own government. In India also, there is federal government.

Question 4.
Write about any two features of the Democracy.
Answer:
1. Enlightened Citizens: In democracy, all the citizens are aware about their rights and duties. They are matured enough to run the administration efficiently.

2. Matured Leadership: Leaders in democracy are also mature because matured leaders are very much necessary to run democratic system efficiently.

Question 5.
Write your views about Economic and Social Equality.
Answer:
1. Social equality: It means all people are equal in society. Nobody can be discriminated on the basis of place of birth, colour of skin, religion, caste and sex. All people are useful organs of the society. No person can be given special status.

2. Economic Equality: It means there should be no difference between the rich and the poor. No class of the society should be exploited. It also means that means of production should not be limited in the hands of a few people. All should have equal opportunities of earning employment.

PSEB 7th Class Social Science Solutions Chapter 18 Democracy and Equality

Question 6.
Why democracy is the most popular form of government in modern times?
Answer:
Today most countries in the world have democratic governments. Such government is welfare-oriented and gives special importance to human rights and freedom. All are treated as equal in the eyes of law. The following are the main features that make democracy very popular :
1. Equality: There is no rich, poor, religious or caste division in democracy. All are equal in the eyes of law.

2. Freedom: People are free from every aspect. They can do any business, can live in any area, can express their ideas freely. But in dictatorship, people have to abide by the ruling of the dictator.

3. The process of making decisions: The decision-making process is in the hands of the people. People choose their representatives and send them to legislatures. The majority party makes the government and runs the administration. The govt, works as per the wishes of general public. If the government does not work properly then it can be changed.

4. Active participation by citizens: All electorates can fight elections or cast then- votes according to their wishes. All are equal participants in the administration of the government but in dictatorship it does not happen.

5. To remove altercations: The ideas of others are respected. Nobody is compelled to adopt anything. The ruling party considers the suggestions of opposition parties as important and the opposition party also co-operates with the ruling party. So, ideological differences are cleared amicably.

6. Growth of human dignity: Freedom, equality and fraternity are the main principles of democracy. Here there is political, social as well as economic freedom and equality.

The Parliamentary Democracy is considered the best government but there are certain conditions to make the democracy successful which are as follows :

2. Capable leaders: If the government is run by educated leadership, the government will be capable. Only wise voters can elect such leadership.

3. Disciplined citizens and political parties: People need to be disciplined and only then they can criticize the wrong policies of the government and can compel the government to work properly. People must respect each other’s ideas. When the political ideology is different, different political parties come into existence. The representatives of the people are elected through elections. So, the political parties should also be very alert and disciplined.

4. Social and economic equality: There is no difference between the rich and poor. Democracy cannot succeed if there are differences in caste, religion, and language.

5. Tolerance: In a democracy, there is a rule of the majority. So, the ruling party must be tolerant. The opposition should also adopt the policy of tolerance which is a prominent feature of democracy.

Forests are natural absorbers of rain water and allow it to seep deep down the soil. Also, the direct pouring of rain is stopped by canopy of forest and it falls drip by drip on the ground. So, water does not stagnate in the forests.

Question 2.
Why is soil of forest rich in nutrients ?
Answer:
The soil of forest is rich in nutrients because dead and decaying leaves are decomposed by decomposers to give a brown coloured nutrient (Humus) to enrich the soil.

Question 3.
Explain why there is no waste in a forest.
Answer:
Forests are habitat of various animals. They excrete and die still there is no waste in forests. Because the dead bodies are food of vultures, crow, jackal and insects. While other things like excreta and remains of dead matter get decomposed by mushrooms and other micro-organisms to nutrients required by soil.

Question 4.
List five products we get from forests.
Answer:
Products obtained from forests are:

  1. Wood,
  2. Oxygen,
  3. Medicinal plants,
  4. Rain,
  5. Lac, Gum, Resin etc.

Question 5.
Explain how animals dwelling in the forest help it grow and regenerate ?
Answer:
Animals live in forest. They either feed on it directly (herbivores) or indirectly (carnivores). In both cases, they consume plants and excrete thrown by their bodies get decomposed by microorganisms to produce simple forms and nutrients. These get dissolved and mixed in soil to be used by growing plants.

Animals also help in scattering seeds to different parts of the forest. When seeds get favourable conditions they grow and thus forests regenerate.

PSEB 7th Class Science Solutions Chapter 17 Forests: Our Lifeline

Question 6.
What are decomposers ? Name any two of them. What do they do in the forest ?
Answer:
Decomposers. The micro-organisms which convert the dead plants and animals to humus are known as decomposers. Examples are bacteria, mushrooms.
Decomposers help in maintaining the supply of nutrients to the growing plants in the forests.

Question 7.
Explain the role of forests in maintaining the balance between oxygen and carbon dioxide in the atmosphere.
Answer:
PSEB 7th Class Science Solutions Chapter 17 Forests Our Lifeline 1
Forests are large area covered with different trees. Trees are green in colour. Their leaves photosynthesize in the sunlight and use atmospheric carbon dioxide to produce oxygen. In this way, balance of oxygen and carbon dioxide is maintained in the forests. In this way forests help in maintaining a balance between oxygen and carbon dioxide in the atmosphere.

Question 8.
Why should we worry about the conditions and issues related to forests far from us ?
Answer:
Forests indirectly or directly influence human life. They control floods and rainfall. They maintain balance of oxygen and carbondioxide in the atmosphere. They are also provider of many useful items needed by us in our daily life. They provide food, shelter and habitat to many animals also. They form a part of food web. So, we should worry about the conditions and issues related to forests far from us.

Question 9.
Explain why there is a need of variety of animals and plants in a forest.
Answer:
When there is variety of animals and plants then opportunity increases for food and habitat for the herbivores. When herbivores increase, then there is also increase in number of carnivores of different varieties. Different varieties of animals help the forest to regenerate and grow.

Question (iv)
How increase in human population is leading to depletion of water table ?
Answer:
Human Population Growth is Responsible for depletion of water table.
As human population is growing rapidly, so does the demand for water for its daily needs. Groundwater is often used for the construction of homes, shops, offices, roads, railways and many other purposes. Such construction also reduces the area under which rainwater seeps underground. In this way we are not only consuming groundwater but also reducing groundwater seepage.

As a result of this ground water level falls. To meet the needs of the growing population, more and more industries need to be set up which makes more use of ground water which causes the groundwater level to fall further. Trees are cut down to meet the needs of the growing population, which deteriorates the water cycle. This is the reason why there is depletion of water table percolating.

Question (v)
Why do plants wilt and finally dry up if they do not get water for some days ?

Long Answer Type Questions

Question 1.
Explain the water cycle process with the help of diagram.
Answer:
PSEB 7th Class Science Solutions Chapter 16 Water A Precious Resource 1
Water Cycle:
There is a constant supply of water on Earth through various natural methods. All these methods together form the water cycle. During the water cycle, water gets to the earth in one of its three forms:
(i) solid (ii) liquid and (iii) gas. Water from earth’s available groundwater sources – oceans, lakes, rivers, lakes, etc. – evaporates through the sun’s heat and remains in the atmosphere. These water vapours condense to form cloud water and fall on the earth in the form of rain. In the solid state, water is in the form of ice and snow on the poles of the earth and in the form of glaciers in the mountains. Together they form the entire water cycle.

  1. Groundwater,
  2. Evaporation,
  3. Condensation,
  4. Clouds,
  5. Precipitation,
  6. Rain.

Question 2.
Explain the factors responsible for groundwater depletion.
Answer:
Factors responsible for the fall in water levels are:
(1) Population growth,
(2) Industrial and agricultural activities,
(3) Low rainfall,
(4) Deforestation,
(5) Decrease in the area for water absorption etc.
are some of the factors which are some of the factors for lowering the ground level.

1. Population growth.
As the population grows, the demand for construction of buildings, shops, offices, roads, and many other institutions increases. This leads to a reduction in open areas such as farmland and playgrounds. Due to this the rate of absorption of rainwater in the soil decreases. Due to this the groundwater level is constantly drying up.

2. Growing Industries.
Water is being used by all industries. Water is needed in the production of everything. Water used by most industries is extracted from the land.

3. Agriculture.
Many farmers depend on rainfall for the irrigation of crops. Irregular rainfall reduces the availability of water. Therefore farmers have to use groundwater for irrigation. Due to population growth, the use of groundwater for agriculture is increasing day by day. As a result, groundwater levels continue to fall.

4. Poor management of water.
When water is supplied through pipes, leakage occurs in the supply pipes which causes a lot of water loss and therefore causes groundwater levels to fall.
