This is the process where wind, water or ice may add a layer of sediment to a landform.

Deposition...

Explanation:

Deposition is a process in which the water, ice and wind for layers of sediments when the fluid flow loses it's kinetic energy. After losing energy, the flow of soil in restricted and a layer over layer of soil is formed by deposition called sediments.
