Question

what is soil erosion list two activitis which cause soil erosion

Answer 1

Loss of the valuable topsoil during rains is another threat to soil. This process is called soil erosion. Soil takes millions of years to form and it can be washed away by wind or water in no time. Plants do not grow in eroded regions because of the absence of nutrients and humus. Soil erosion thus results in a loss of plant life and converts previously fertile land into barren land.

The activities which lead to soil erosion are deforestation and excess of irrigation.
