Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

Front

What is an example of mechanical weathering?

Back

An example of mechanical weathering is when water freezes in cracks of rocks and expands, causing the rock to break.
