Question

Main cause of soil erosion

• A. Afforestation
• B. Less rains
• C. Thinning of ozone layer
• D. Deforestation

Answer 1

The correct option is D Deforestation

In deforestation, there is the cutting or the removal of plants. The roots of the plants allow the soil to be held due to the presence of water. Due to deforestation, the water present in the soil gets evaporated resulting in a barren land. This barren land is prone to soil erosion which results in the loss of the upper layer of the soil. When new trees are planted, the soil erosion can be prevented.

Thus, the correct answer is option D.
