FAQs on Land, Soil, Water, Natural Vegetation and Wildlife Resources Class 8 Worksheet Social Science

1. What are the main factors that influence land degradation?
Ans. Land degradation is influenced by several factors, including deforestation, overgrazing, improper agricultural practices, urbanization, and industrialization. These activities lead to soil erosion, loss of fertility, and the destruction of natural vegetation, ultimately resulting in land degradation.
2. How does soil erosion affect agricultural productivity?
Ans. Soil erosion has a negative impact on agricultural productivity. When the topsoil is eroded, essential nutrients and organic matter are lost, leading to a decrease in soil fertility. This, in turn, reduces crop yields and can even render the land unsuitable for cultivation.
3. What are the consequences of water pollution?
Ans. Water pollution can have severe consequences on both human health and the environment. Contaminated water can lead to waterborne diseases, such as cholera and dysentery. It also disrupts aquatic ecosystems, causing the decline of fish populations and the destruction of natural habitats.
4. How does deforestation contribute to climate change?
Ans. Deforestation significantly contributes to climate change. Trees absorb carbon dioxide, a greenhouse gas that traps heat in the atmosphere. When forests are cleared, the stored carbon is released into the atmosphere, contributing to the greenhouse effect and global warming.
5. What are the benefits of conserving natural vegetation and wildlife resources?
Ans. Conserving natural vegetation and wildlife resources is crucial for maintaining ecological balance. It helps in preserving biodiversity, protecting habitats, and ensuring the sustainability of ecosystems. Additionally, natural vegetation acts as a carbon sink, helping to mitigate climate change. Wildlife resources also provide economic opportunities through ecotourism and the sustainable use of natural resources.
