Erosion Processes

Question 1

Abrasion

Answer 1

sediment and stones are picked up by the waves and wear away at the cliff/headland

Question 2

Hydraulic action -

Answer 2

this is the shear force of the waves forcing air at high pressure into cracks in the cliff over time this weakens the rock and causes the joint to widen

Question 3

Attrition

Answer 3

as rocks are moved around by the water they knock into each other gradually becoming smaller and rounder

Question 4

Corrosion solution

Answer 4

weak acids in seawater dissolve the rock particles

Question 5

Factors affecting erosion
The amount of erosion is influenced by a range of factors

Answer 5

Wave type
Wave size
Lithology( weaker rock erode quicker

Question 6

Wave type and size affects the seasonal changes in the amount of erosion
Erosion tends to happen more during the

Answer 6

winter due to a greater number of destructive waves

Question 7

The size and type of waves affects the amount of

Answer 7

hydraulic action and abrasion
