B. Over cultivation
C. Deforestation
D. All of these

Answer

Correct Answer: D. All of these

Detail about MCQs

All of the options listed (unrestricted grazing, over cultivation, and deforestation) are causes of soil erosion.

Unrestricted grazing: When livestock graze excessively in an area without proper management, they can remove vegetation cover, expose the soil surface, and trample soil, making it more vulnerable to erosion by wind and water.

Over cultivation: Intensive or improper farming practices, such as continuous plowing, monoculture cropping, and lack of soil conservation measures, can lead to soil degradation and erosion.

C. Deforestation: Cutting down trees and clearing forests for agriculture, logging, urbanization, or infrastructure development exposes the soil to erosion. Tree roots help stabilize soil, and the canopy intercepts rainfall, reducing the impact of rainfall on the soil surface.
