B. Erosion is the breaking down of rocks into sediments by physical or chemical processes; deposition is the accumulation of sediments in low-lying areas due to the action of gravity, water, ice, or wind.

C. Erosion is the removal of sediments by gravity, water, ice, or wind; deposition is the accumulation of sediments in low-lying areas due to the action of gravity, water, ice, or wind.
D. Erosion is the breaking down of rocks into sediments by physical or chemical processes;
deposition is the removal of sediments by gravity, water, ice, or wind.
