What is deposition in the rock cycle? | Socratic

Mar 24, 2016·Deposition is when sediments, soil, or rocks are added to the land. It is the opposite of erosion. Deposition is when sediments, soil, or rocks are added to the land. It is the opposite of erosion. Deposition is a constructive process, because it builds or creates landforms. Just as wind, water, and other forces can wear away sediments over time, sediments must also be deposited.
