has participant soil soil erosion Soil erosion is a process in which exogenic processes remove soil from one location on the Earth's crust and transport it to another location where it is deposited. "Soil Erosion is a common term that is often confused with soil degradation as a whole, but in fact refers only to absolute soil losses in terms of topsoil and nutrients. This is indeed the most visible effect of soil degradation, but does not cover all of its aspects. Soil erosion is a natural process in mountainous areas, but is often made much worse by poor management practices." http://www.fao.org/soils-portal/soil-degradation-restoration/en/ envoPolar planetary erosion
