Exploring Weathering, Erosion, and Deposition

What is the primary cause of physical weathering?

• Temperature changes

• Plant growth

• Chemical reactions

• Mechanical forces

How can plants contribute to weathering?

• By absorbing water

• By providing shade

• By growing into cracks and expanding them

• By producing acids
