Question

.Define the term soil erosion. What are the different types of soil erosion?

Answer 1

Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

Answer 2

removal of topsoil faster than the soil forming processes can replace it, due to natural, animal, and human activity (over grazing, over cultivation, forest clearing, mechanized farming, etc.). soil erosion results in land infertility and leads to desertification and devastating flooding... 

there are four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion....
