Erosion
Erosion is the displacement of solids by the agents of wind, water or ice, by downward or down-slope movement in response to gravity or by living organisms . Erosion is well-known from weathering, which is the decomposition of rock and particles through processes where no movement is caught up, although the two processes may be concurrent.
Erosion is an intrinsic normal process but in many places it is increased by human land use. Poor land use practices include deforestation, overgrazing, unmanaged construction movement and road or trail building. wever, improved land use practices can limit erosion, using techniques like terrace-building and tree planting.A certain amount of erosion is natural and, in fact, healthy for the ecosystem. For example,
gravels repeatedly move downstream in watercourses. Excessive erosion, however, can cause problems, such as in receipt of water sedimentation, ecosystem damage and outright loss of soil.
