Detailed explanation-1: -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-2: -Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
Detailed explanation-3: -Sediments transported and deposited by glacial ice are known as till. Subglacial sediment (e.g., lodgement till) is material that has been eroded from the underlying rock by the ice, and is moved by the ice. It has a wide range of grain sizes, including a relatively high proportion of silt and clay.
