Weathering and Erosion Quiz

What is the definition of weathering?

• The breaking down of rocks into smaller pieces

• The transportation of rock and soil by natural forces

• The formation of new rocks from magma

• The melting of ice into water

Which type of weathering involves the crumbling of rocks due to water and temperature changes?
