What is the difference between chemical and physical weathering?

• Chemical weathering involves chemical reactions, while physical weathering involves physical forces
• Chemical weathering is a fast process, while physical weathering is a slow process
• Chemical weathering breaks down rocks, while physical weathering creates new landforms
• Chemical weathering involves physical forces, while physical weathering involves chemical reactions

What is the main way that rocks get broken down through physical weathering?

• Ice wedging
• Root pry
• Animal activity
• Abrasion

Which of the following is an example of chemical weathering?

• Abrasion
• Root pry
• Oxidation
• Ice wedging

How does ice wedging contribute to physical weathering?

• By physically breaking down rocks
• By creating new landforms
• By moving sediment and debris
• By freezing and expanding in cracks
