Why does erosion always lead to deposition?

Answer 1

Because erosion means the movement of sediment then since deposition means the settling of sediment in a new location the movement of the sediment is settling down.

Answer 2

Erosion involves the process of wearing away materials, such as soil and rocks, from one place and transporting them to another location. Eventually, the eroded materials settle and accumulate in new areas through deposition due to factors like gravity, water flow, or wind settling them down. This continuous cycle of erosion and deposition is a natural process that reshapes the Earth's surface over time.
