Question 1: Answer the following questions.
(i) Which are the two main climatic factors responsible for soil formation?
(ii) Write any two reasons for land degradation today.
(iii) Why is land considered an important resource?
(iv) Name any two steps that government has taken to conserve plants and animals.
(v) Suggest three ways to conserve water.
Answer 1: (i) The two main climatic factors responsible for soil formation are temperature and rainfall. These factors influence the rate of weathering of rocks and the decomposition of organic matter, both of which contribute to soil formation.
(ii) Two reasons for land degradation today are:
- Deforestation – The removal of trees reduces soil fertility and increases erosion.
- Overuse of chemical fertilizers and pesticides – These deplete soil nutrients and cause pollution.
(iii) Land is considered an important resource because:
- It supports agriculture, which provides food for the population.
- It is essential for human settlements, industries, and infrastructure development.
- It sustains biodiversity by providing habitats for plants and animals.
(iv) Two steps taken by the government to conserve plants and animals are:
- Establishment of national parks, wildlife sanctuaries, and biosphere reserves to protect endangered species and their habitats.
- Implementation of laws like the Wildlife Protection Act to prevent illegal poaching and deforestation.
(v) Three ways to conserve water are:
- Rainwater harvesting – Collecting and storing rainwater for future use.
- Drip irrigation – Using water-efficient irrigation techniques to reduce wastage.
- Fixing leaks and reducing water wastage – Ensuring taps and pipes do not leak and using water judiciously in daily activities.
Question 2: Tick the correct answer.
(i) Which one of the following is NOT a factor of soil formation?
(a) time
(b) soil texture
(c) organic matter
Answer 2: (b) Soil texture
Question 2: Which one of the following methods is most appropriate to check soil erosion on steep slopes?
(a) shelter belts
(b) mulching
(c) terrace cultivation
Answer 2: (c) Terrace cultivation
Question 2: (iii) Which one of the following is NOT in favour of the conservation of nature?
(a) switch off the bulb when not in use
(b) close the tap immediately after using
(c) dispose polypacks after shopping
Answer 2: (c) Dispose polypacks after shopping
Question 3: Match the following.
| (i) Land use | (a) Prevent soil erosion |
| (ii) Humus | (b) narrow zone of contact between the lithosphere, hydrosphere and atmosphere |
| (iii) Rock dams | (c) Productive use of land |
| (iv) Biosphere | (d) Organic matter deposited on top soil |
| (e) Contour ploughing |
Answer 3:
- (i) Land use → (c) Productive use of land
- (ii) Humus → (d) Organic matter deposited on topsoil
- (iii) Rock dams → (a) Prevent soil erosion
- (iv) Biosphere → (b) Narrow zone of contact between the lithosphere, hydrosphere, and atmosphere
Question 4: State whether the given statement is true or false. If true, write the reasons.
(i) Ganga–Brahmaputra plain of India is an overpopulated region.
(ii) Water availability per person in India is declining.
(iii) Rows of trees planted in the coastal areas to check the wind movement is called intercropping.
(iv) Human interference and changes of climate can maintain the ecosystem.
Answer 4: (i) True – The Ganga–Brahmaputra plain is an overpopulated region because it has fertile soil, which supports agriculture, and access to water resources, making it suitable for human settlement and economic activities.
(ii) True – Water availability per person in India is declining due to population growth, excessive groundwater extraction, pollution of water bodies, and climate change affecting rainfall patterns.
(iii) False – Rows of trees planted in coastal areas to check wind movement are called shelterbelts or windbreaks, not intercropping. Intercropping refers to growing two or more crops simultaneously on the same field to improve soil fertility and reduce pests.
(iv) False – Human interference and climate changes often disrupt the ecosystem rather than maintain it. Activities like deforestation, pollution, and urbanization, along with climate change, lead to habitat destruction, loss of biodiversity, and imbalance in ecosystems.
