Question

how does the action of deposition contrast with the actions of weathering and erosion?
weathering and erosion allow for the building of new land masses. deposition is the wearing away of land masses.
deposition is a building process. weathering and erosion are wearing - down processes.
deposition always occurs slowly, over a long period of time. weathering and erosion always occur quickly.
weathering and erosion allow for the formation of fossils. deposition is the breaking up of fossils.

Explanation:

Weathering is the breakdown of rocks, minerals, etc. Erosion is the movement of weathered materials. Both are wearing - down processes. Deposition is the laying down of sediments (by wind, water, etc.), which is a building process.

Answer:

Deposition is a building process. Weathering and erosion are wearing - down processes.
