Wind erosion a)removes the fertile b horizon of soil b)can be reduced by cutting down trees c)happens slowly in dry climates d)is both destructive and constructive

Option (A)

Explanation:

Erosion refers to the process of removal of sediments from one place to another. Wind erosion is a type of erosion where the agent is the wind that carries the sediment particles from the soil and due to this, the fertility of the soil decreases. It degrades the quality of the soil (land). It takes place commonly on the flat (plane) land areas in the dry type of environment or sandy areas where there is a lack of rainfall and moisture content in the soil.

Thus, wind erosion removes soil fertility.

Thus, the correct answer is option (A).
