Detailed explanation-1: -Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.
Detailed explanation-2: -“Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water.”
Detailed explanation-3: -Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
Detailed explanation-4: -erosion, removal of surface material from Earth’s crust, primarily soil and rock debris, and the transportation of the eroded materials by natural agencies (such as water or wind) from the point of removal.
