Question

X visits his drought-hit village and realises that the groundwater level has gone down. The soil has lost its moisture content. He concludes that this degradation of soil is due to soil erosion.

What are the causes of soil erosion?

• A. Cutting down of trees for mining purpose
• B. Overgrazing
• C. Change in the colour of soil and texture
• D. Hybrid crops growing in the field

Answer 1

Answer: (A), (B)

The correct options are
A Cutting down of trees for mining purpose
B Overgrazing

The man-made causes of soil erosion are deforestation, overgrazing, mining and construction. Sometimes, the running water cuts through the clayey soils and leads to gully erosion. Natural forces like wind, glaciers and water also lead to soil erosion.
