What happens in the erosional process solution?
Chemical reaction between the sea water and susceptible rock
1 of 8
What happens in the erosional process attrition?
Material in the water hit against each other. This makes them smaller and more rounded.
2 of 8
explain the erosional stages taking place during hydraulic action.
1) Water is compressed into cracks in the rock from battering waves.
2) This repeated action breaks the rock down through the cracks expanding.
3 of 8
'pieces of rock are picked up by waves and hit against the bed, beach or cliffs. This wears them away over time.
Abrasion
4 of 8
Explain what is meant by cavitation.
1) Waves hit cliffs and air bubbles are forced into cracks.
2) pressure compresses the air bubbles, forcing them into solution.
3) As the wave retreats pressure is reduced and the air comes out of the solution, causing micro-detonations which enlarge crac

What is the definition of solution 1?
Calcium carbonate in rocks such as limestone is dissolved.
6 of 8
What is the definition of solution 2?
Corrosion of rocks by the salt in the sea water.
The evaporation of the salts from the water causes crystals to form and grow in the crack of the rock, putting them under stress.
