Answer:
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.
1) Sheet erosion by water; 2) Wind erosion; 3) Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides; 4) Gully erosion – when water runoff removes soil along drainage lines
It is the natural process of wearing away of the topsoil, but human activities have accelerated the process. It is usually caused due to the removal of vegetation, or any activity that renders the ground dry. Farming, grazing, mining, construction and recreational activities are some of the causes of soil erosion.

Answer:
The removal of the topsoil by water, wind and human activities is called soil erosion.
Two ways to prevent soil erosion are:
- Shelter belts: Trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind.
- Constructing dams: Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.
