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 coastal areas to check wind movement are called intercropping. (iv) Human interference and climate changes can maintain the ecosystem. 5. Activity: Discuss some more reasons for changes in land use patterns. Has your place undergone any change in the land use pattern in recent years?
Understand the Problem
The question set contains multiple questions related to environmental studies, soil formation, land use, and conservation methods. It asks to answer specific questions, select correct options, match pairs, determine the truth of statements, and discuss changes in land use patterns.
Answer
(i) Temperature and rainfall; (ii) Deforestation, chemicals; (iii) Supports life; (iv) National parks, sanctuaries; (v) Rainwater harvesting, fix leaks.

More Information
Temperature and rainfall significantly influence weathering and erosion processes which affect soil formation. Conservation efforts like setting up protected areas are crucial for maintaining biodiversity.
Tips
A common mistake is confusing climatic factors affecting soil formation with human influence factors affecting land degradation.
