Attririon
This is when bumpy and rigid rocks are carried into the waves, which then smash into each other and slowly become smoother, smaller and broken down.

Corrasion
This is when waves take materials, and throw them at the cliffs wearing them away.
Hydraulic action
water is forced into gaps in the cliff, and as the water comes out, it takes some material with it eroding it down.
