Which of the following best describes chemical weathering?

• A process in which ice wears away at rocks over a long period of time

• A series of changes that moves rocks from one area to another

• Any small-scale event such as rain or fog

• A process that changes the composition of rocks, causing them to break down

How do weathering and erosion differ?

• Weathering breaks down rocks; erosion moves them.

• Weathering has to do with air; erosion has to do with rocks.

• Weathering occurs only in winter; erosion occurs year-round.

• Weathering can be chemical or physical; erosion is only chemical.
