Given below are two statements: Assertion (A): Water erosion is due to the dispersive action and transporting power of water as it descends in rain and leaves the land in the form of run-off. Reason (R): Water erosion is caused by people who remove protective plant covers by tillage operation, burning crop residues, over grazing, over cutting forests, etc.

The wind erosion equation method is:

The minimum wind velocity required to initiate the movement of soil particle is called:

Erosion is function of:

Which is not the process of wind erosion?

The vulnerability of the soil to erosion is called:

The soil loss equation is:
