Deposition is the Process of Dropping Eroded Material

  • Deposition- when material being transported is dropped on the coast.
  • Marine deposition- when sediment carried by seawater is deposited.
  • Aeolian deposition- when sediment carried by wind is deposited.
  • Happens when the sediment loadexceeds the ability of the water or wind to carry This can be because sediment load increases, or because wind or water flow slows down.
  • Friction increases- if waves enter shallow water or wind reaches land, friction between the water/wind and ground surface increases, which slows down the water or wind.
  • Flow becomes turbulent- if water or wind encounters an obstacle, flow becomes rougher and overall speed
