Here's a breakdown:

* Erosion: The process of wearing down and transporting rock and soil. This can be caused by wind, water, ice, or gravity.

* Transportation: The movement of eroded material.

* Deposition: When the energy of the transporting force decreases, the eroded material is dropped or deposited in a new location.

Deposition is a key part of the rock cycle and plays a major role in shaping the Earth's surface.
