erosion
n.
gradual wearing away of the Earth by wind or water; disintegration; deterioration
Erosion
Erosion is displacement of solids (
soil,
mud,
rock and other particles) usually by the agents of currents such as, wind, water, or ice by downward or down-slope movement in response to
gravity or by living organisms (in the case of
bioerosion).Erosion is distinguished from
weathering, which is the breaking down of rock and particles through processes where no movement is involved, although the two processes may be concurrent.Erosion is an intrinsic natural process but in many places it is increased by human
land use. Poor land use practices include
deforestation,
overgrazing, unmanaged construction activity and road or trail building. However, improved land use practices can limit erosion, using techniques like
terrace-building and tree planting.
