What is the process called when existing rocks are broken down into small pieces?

• Deposition

• Compaction

• Weathering

• Erosion

Which type of weathering involves temperature changes causing rocks to break apart?

• Biological weathering

• Chemical weathering

• Thermal weathering

• Physical weathering

What happens during freeze-thaw weathering?

• Plants grow into the rock and break it apart

• Rocks are dissolved by acid rain

• Water gets into cracks and freezes, expanding and breaking the rock

• Water evaporates from the rock
