Explanation:

Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water.”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.Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans. The removal of fertile top soil land by wind or water is called soil erosion. Soil erosion occurs easily in those areas of land which are not covered by vegetation (trees and other plants) or have very little vegetation. The cover of vegetation softens (or reduces) the effect of heavy rains on the soil.

Soil Erosion good or bad?

Soil erosion removes valuable top soil which is the most productive part of the soil profile for agricultural purposes. The loss of this top soil results in lower yields and higher production costs. When top soil is gone, erosion can cause rills and gullies that make the cultivation of paddocks impossible.
