Waves hit the bottom of the cliff eroding a notch. The cliff above the notch is undercut and the overhanging rock eventually falls.

How are wave cut platforms formed?
As the cliff erodes, it leaves behind flat rocks and rock pools which make up the platform
12 of 16
How are headlands and bays formed?
If the coast is made of alternating soft and hard bands of rock, destructive waves will erode the soft rock to form bays and coves. The more resistant rock sticks out forming headlands.
13 of 16
Caves?
A joint or fault in resistant rock. Abrasion and hydraulic action widen the joint into a cave.
14 of 16
Arches?
Waves make the cave larger until it cuts through the headland to make an arch
15 of 16
Stacks?
The arch is eroded and the roof becomes too heavy and collapses to a stack. This eventually gets eroded into a stump

This depends on: how strong the wind is, how long it blows for and how far the wave travels.
