Soil erosion - Wikipedia

Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradationThis natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humansIn accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic ,
