Explanation:
Detailed explanation-1: -Topsoil is the uppermost layer of the Earth’s surface layers. Top soil is soft and light and can be carried away easily. Water and wind cause the topsoil to be removed. This process of carrying of top soil by wind and water is called as soil erosion.
Detailed explanation-2: -Removal of top fertile layer of the soil is called soil erosion.
Detailed explanation-3: -The removal of excess water either from the ground surface or from the rootzone, is called drainage.
