soil erosion is a two-step process in which soil particles are detached in response to an energy input and then transported.Eroding soil can be moved by wind, water, ice, or gravity. These erosion processes redistribute soil within a landscape and can remove soil under some conditions. Soil loss by erosion remove topsoil from a soil profile. Areas subject to soil loss by erosion are typically less productive because of lower water-holding capacity and decreased fertility. Blowing soil can damage crop plants and soil deposition can bury small plants.
