Soil erosion is removal of top soil by agency of water (water erosion) and wind (wind erosion). Soil erosion is of two types- natural and anthropogenic. Natural or geological erosion is extremely slow removal of top soil due to rain water or wind. Anthropogenic soil erosion is caused by removal of plant cover through over grazing, litter collection, tree felling, leaving the soil unprotected during agricultural operations.

Soil erosion is the removal of top soil by the agency of water (water erosion) and wind (wind erosion). Soil erosion is of two types, natural and anthropogenic. 

Soil erosion is the removal of top soil, top soil has all the nutrients necessary for plant growth. Eroded soil is low on fertility

Soil erosion is the process of washing and wearing away of the top fertile soil due to the physical pressure and force of water, wind or other farming activities like tilling, ploughing etc.
The soil can be prevented from getting eroded by planting and raising more trees as the roots of the trees hold the soil tightly and prevents it from getting washed away.
Deforestation means cutting down of trees and more we cut down the trees more the soil will be left loose and easily washed away and get eroded.
Excessive use of fertilizers can leave the soil degraded, loose, dry and barren and more vulnerable and easier to get eroded.
Overgrazing by animals can leave the soil loose, dry and barren totally exposed to get washed away and get eroded completely.

Soil erosion involves the removal of the top layer of soil which adversely affects the fertility of the soil. Heavy rainfall leads to splashing of soil. However, the majority of the soil splashed is not immediately lost from the field. Most of the splashed soil particles don't leave the field, they clog surface pores, which in turn reduces water infiltration, increases water runoff, and increases soil erosion.
