OCR A Level Geography - Weathering & Mass Movement

Weathering is the...

• removal of material

• breakdown of material in its place (in situ)

• physical breakdown of material

Which of these physical weathering processes is most likely in coastal environments?

• Freeze-thaw

• Chemical weathering

In which climate is biological weathering most likely?

• Polar

• Temperate

• Tropical

• Desert

Which chemical weathering process requires an abundance of water?

• Oxidation

• Carbonation

• Hydrolysis

• Hydration

What is the best definition of mass movement?

• Large scale movement of material

• The movement of material downslope under the influence of gravity

• The movement of material due to loss of friction

What conditions make mass movement more likely?

• Weathered material

• Shallow slopes

• Abundance of water in the material

• Lack of water in the material

Which of these mass movement types is slowest?
