WebErosion is a broadly defined group of processes involving the movement of soil and rock. This movement is often the result of flowing agents, whether wind, water, or ice, which sometimes behaves like a fluid in the large mass of a glacier. Gravitational pull may also influence erosion.

A river uses energy to carry out its 'work' of erosion, transport and deposition of sediment and to move the water in its channel. This energy is produced when water flows down a slope, so the height of a river above sea level determines this. The lowest level of a river is called the base level, and for most rivers it is sea level. optically pure meaning
