Explanation: Deposition occurs when the agents such as wind or water deposits sediments of weathered surface materials to a land mass.
Deposition is a geological process in which sediments such as ash, soil, and weathered rock materials are deposited back to the earth's surface via gravitational pull and the sediments are added to a landform.
Agents of deposition include wind, ice, water and gravity transport. Weathered surface material are deposited, building up layers of sediment.
