Question 40.
What is the basic structure of the T Constitution?
Answer:
The Constitution of India does not describe as what is the basic structure of the Constitution. But the Supreme Court has done it.

The basic structure of the constitution is as follows:
“every provision of the Constitution is essential; otherwise it would not have been put in the Constitution. This is true. But this does not place every provision of the Constitution in the same position. The true position is that every provision of the Constitution can be amended provided the basic foundation and structure of the Constitution remains the same.

The basic structure may be said to consist of the following features:

  • Supremacy of the Constitution;
  • Republican and Democratic form of Government;
  • Secular character of the Constitution;
  • Separation of powers between the legislature, the executive and the judiciary;
  • Federal character of the Constitution.”

“The above structure is built on the basic foundation, i.e., the dignity and freedom of the individual. This is of supreme importance. This cannot, by any form of amendment, be destroyed,” The Supreme Court said this in its judgement on the Kesavananda Bharati case.

Question 41.
Explain terms such as “sovereign’, ‘democratic’, and republic.
Answer:
The Constitution proclaimed India to be a sovereign democratic republic. This three words-sovereign, democratic and republic are significant. Sovereignty means supreme power. It means the right of people to take decisions on internal matters as well as policies determining our relations with other countries. As the authority of the government rests upon the support of the people, people are sovereign. Democracy means people enjoy equal political rights.

They include right to form associations, right to criticise and oppose policies of government, right to contest elections and hold public offices. People have a right to elect a government through periodical, free and fair elections. Government is responsible to people and exercises powers only as defined in the Constitution.

No government can continue in power without the support of majority of people’s representatives in the legislature. People can change the government in elections. Republic means that the head of the State (President) is an elected person. He/ she wields power for a fixed term. India is a Union of States.

Question 42.
Compare the grant of the democratic rights as it came in the European countries and in India.
Answer:
European countries had developed industrially before they became full-fledged democracies. But in India democracy came before any such substantial industrial development. At the time of its Independence, India was predominantly an agrarian economy. Illiteracy was widespread. Poverty was rampant. This was an unusual experiment in establishing democracy in conditions of mass poverty. European countries had become strong nations by the time they became democratic.

The situation was different in. our country. The task of building the nation in real sense started after we became a democracy. In Europe and America expansion of democracy took place by limiting the powers of government. People there believed that freedom is possible if there is no unnecessary interference of government in private affairs of the individual.

So they fought for freedoms against absolutist governments. But in India, government was assigned a larger role from the beginning: We wanted the state to bring about all-around development. So the expansion of democracy in India has been bound with the expansion of government.

Thus in the history of the Western nations, expansion of democracy was associated with industrialisation, emergence of strong nations, militant struggles for voting rights and limiting the governmental powers. Those countries went through these stages one after the other, over a period of nearly 200 years. But in India democracy had to address these issues all at the same time.

The country has to industrially develop, build a nation and national government, transform social relations, and meet the basic needs of the people. The Indian state had to simultaneously pursue these, goals in a democratic framework.

Question 29.
Give two main reasons of forest fire.
Answer:

  1. Natural fire due to lightning.
  2. Fire purposely caused by local inhabitants.

Question 30.
Varied characteristics of land and climate affect the distribution of population. Explain how.
Answer:
Varied characteristics of land and climate affect the distribution of population in the following ways –

  • The rugged topography, steep slopes of mountains, low-lying areas susceptible to waterlogging, desert areas, thick forested areas are sparsely populated or uninhabited.
  • Fertile plains and river valleys offer suitable land for agriculture. Therefore, these are densely populated.

Question 31.
Explain how various factors affect soil formation.
Answer:

  • Parent Rock – It determines colour, texture, chemical properties, mineral content and permeability of the soil.
  • Relief-Altitude and slope determine the accumulation of soiL
  • Climate – Temperature and rainfall influence rate of weathering and humus formation.
  • Time – It determines the thickness of soil.
  • Flora, Fauna and micro-organisms – These affect the rate of humus formation.

Question 32.
Describe five methods of soil conservation.
Answer:

  1. Mulching- The bare ground between plants is covered with a layer of organic matter like straw. It helps to retain soil moisture.
  2. Contour barriers – Stones, grass, soil are used to build barriers along contours. Trenches are made in front of the barriers to collect water.
  3. Agroforestry- Crops are grown along with trees on the boundaries of the fields to check soil erosion.
  4. Rock dam – Rocks are piled up to slow down the flow of water. This prevents gully erosion.
  5. Intercropping- Different crops are grown in alternate rows and are sown at different times to protect the soil from rain wash.

Question 33.
Describe the distribution of water on the earth’s surface.
Answer:

  • Oceans cover two-thirds of the earth’s surface.
  • The freshwater accounts for only about 2.7 per cent of the total. Nearly 70 per cent of this occurs as ice sheets and glaciers in Antarctica, Greenland and mountain regions. Only one per cent of freshwater is available as groundwater, surface water in rivers and lakes and as water vapour in the atmosphere.

Question 34.
Mention the various ways of water conservation.
Answer:

  • The rainwater can be collected from the rooftop with the help of pipes in tanks, sumps, ponds or lakes. It also helps in recharging of groundwater.
  • The canals must be properly lined to minimise losses by water seepage.
  • Sprinklers effectively irrigate the area by checking water losses through seepage and evaporation.
  • In dry regions with high rates of evaporation, drip irrigation is very useful.

Question 35.
Write four advantages of rainwater harvesting.
Answer:

  1. It makes ecological and financial sense not to waste pure natural resources available in large quantity on rooftops.
  2. It encourages water conservation and self-dependence.
  3. If water does not contain any organic material and is stored in a clean container, it remains pure for long time.
  4. It prevents groundwater depletion and is a good supplement to piped water.

Class 7 Science Chapter 5 Acids Bases And Salts Extra Questions Question 18.
Three liquids are given to you. One is hydrochloric acid, another is sodium hydroxide and third is a sugar solution. How will you identify them? You have only turmeric indicator.
Answer:
Turmeric solution turns red on coming in contact with bases. It is not affected by acids and neutral substances. At first we will identify the base. Samples of the given three liquids are tested by adding a small quantity of turmeric to them.

The liquid in which the colour of turmeric changes from yellow to red, is a base, i.e., sodium hydroxide solution. Then, one of the remaining two unidentified solutions is added to it gradually. If the solution turns yellow again, the added liquid is hydrochloric acid (because it neutralises the base). Otherwise, the added liquid is sugar solution.
