What role does water play in weathering?

Back

Water can enter cracks in rocks, freeze, and expand, causing the rocks to break apart, which is a form of physical weathering.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken pieces to new locations.
