Detailed explanation-1: -Wind Deposition. Like water, when wind slows down it drops the sediment it’s carrying. This often happens when the wind has to move over or around an obstacle. A rock or tree may cause wind to slow down.

Detailed explanation-2: -The movement of sediments by wind, water, ice, or gravity is called erosion. Sediments are dropped in a new location. The process of dropping sediments in a new location is called deposition.

Detailed explanation-3: -Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice. Sediment can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by organic activity (e.g. as sea shells) or by evaporation.

Detailed explanation-4: -Sediment in rivers gets deposited as the river slows down. Larger, heavier particles like pebbles and sand are deposited first, whilst the lighter silt and clay only settle if the water is almost still.

Detailed explanation-5: -Aeolian processes are those processes of erosion, transport, and deposition of sediments that are caused by wind at or near the surface of the earth. Sediment deposits produced by the action of wind and the sedimentary structures characteristic of these deposits are also described as aeolian.
