â¢ Erosion and deposition are continuous geological processes that are natural and result in relief features seen over the surface of the earth. â¢ If erosion is seen as a sequence of events, deposition takes place at last when the rock particles finally settle down on the surface of earth.
1 Deposition is the dropping, or depositing of sediment by water, wind or ice. 2  Deposition builds up new land on Earthâs surface, like a delta at the end of a river or the pile up of a sand dune in the desert. 3  Shells on the beach are deposition by the ocean waves.
