What is weathering?
It is the process by which water, ice, wind, or gravity move pieces of rock and soil.
It is the process where rock is dissovled, worn away, or broken down into small pieces.
It is the dropping of sediment by wind, water, ice or gravity.
The movement of sediment from one place to another is the process of...
