What happens to a rock when it weathers?

• It settles out of water that is carrying it.
• It creates a valley.
• It forms a delta.
• It breaks into small pieces.

Physical and chemical weathering both

• change rocks into new materials.
• dissolve rocks.
• break rocks into smaller pieces.
• require exposure to air.

Physical and chemical weathering differ because

• only chemical weathering produces new materials.
• only physical weathering creates smaller pieces of rock.
• only physical weathering involves water.
• chemical weathering is faster than physical weathering.
