• Water to freeze and thaw

• High amount of feldspar

What is the name given to loose rock materials?

• Bedrock

• Soil

• Regolith

• Corestone

What is step B?

• Rapid heat loss during the day

• Overlying pressure is released (unloading)

• Radial cracks enlarge

Which weathering processes are present in the diagram?

• Mechanical

• Chemical

• Spheroidal

• Pressure release

What is the landform shown?

• Scree

• Tor

• Sheeting

• Pineapple bun

Which of the following are factors that facilitate weathering processes?

• Abundant rainfall facilitates chemical weathering

• Thick soil profiles facilitate weathering

• Rocks with minerals that expand at different rates facilitate mechanical weathering

• The shorter time period the rock is exposed to air the more it is weathered
