Water can cause both physical and chemical weathering; it can freeze and expand in cracks, breaking rocks apart, or dissolve minerals in rocks.

Front

What is an example of physical weathering?

Back

Ice expanding in cracks of rocks.

Front

What is an example of chemical weathering?

Back

Acid rain reacting with limestone to form calcium carbonate.

Front

What is the difference between weathering and erosion?

Back
