Detailed explanation-1: -The removal of topsoil by the natural forces is known as soil erosion.
Detailed explanation-2: -Sheet and rill erosion Sheet erosion occurs when a thin layer of topsoil is removed over a whole hillside paddock-and may not be readily noticed. Rill erosion occurs when runoff water forms small channels as it concentrates down a slope. These rills can be up to 0.3m deep.

Detailed explanation-4: -Sheet erosion or also commonly known as sheet wash can be defined as the washing off the soil surface in thin layers as a result of rainfall. Soil erosion occurs in a wide area mostly in the coastal and flood-prone areas.
Detailed explanation-5: -One example of sheet erosion is when loose soil that covers a hill is washed down a slope by rainwater that flows consistently. Another example of sheet erosion is when a layer of soil that was freshly plowed or evened out starts to erode evenly from a flow of water.
