What is deposition?

Back

Deposition is the process where materials are added to a landform or land mass, often occurring after erosion when the transporting medium loses energy.

How does water contribute to landform changes?

Back

Water can erode landforms through flowing rivers and can also deposit materials, creating new landforms like deltas.
