Deposition is the laying down of material that has been removed by denudation. Most of the material will be sediment and therefore a possible source of sedimentary rocks when consolidated.

 

After denudation has taken place, the material is transported, sometimes over quite considerable distances, before being deposited. Most of the material will eventually be dumped on the seabed by rivers. However, there will be some deposition on land – for example, silt of flood plains, till deposited by ice, and loess deposited by wind.

 

Together with denudation, deposition is the major process which creates the Earth's landscape.
