1
Q
What are subariel processes?
A
include weathering, mass movement and rock breakdown processes. *
2
Q
importance
A
weathering causes rock to breakdown and the cliff/rock structure to be substantially weakened.
3
Q
mechanical weathering
A
freeze thaw- puts pressure on the air in the cracks in rock, widening the bedding planes.
more likely in wet/cold environments
4
Q
biological weathering
A
when plants bore into rock and the fungi release chemicals which dissolve them before they are then consumed.
more important in wet/warm environments.
5
Q
chemical weathering
A
acidic rainwater formed by C02 in the air reacts with calcium carbonate in limestone causing it dissolve by carbonation.
