Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass.Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.. Deposition occurs when the forces responsible for sediment transportation are no longer sufficient to ...
