Parts of rocks and sediment transported by the waves smash and grind against rocks and cliffs. This causes the rocks and cliffs to weaken further causing them to break - smoothing the surface.
1 of 5
Hydraulic Action
Air is forced into cracks in the rocks and compresses when a wave hits. The pressure applied causes the rocks to break off.
2 of 5
Quarrying
The energy of a wave as it breaks against a cliff is enough to detach parts of the rock.
3 of 5
Corrosion/Solution
Soluble rocks (limestone, chalk) get gradually dissolved by the seawater.
4 of 5
Attrition
Bits of rock in the water smash against each other and break into smaller debris.
