Sea cliffs composed of clay or chalk are susceptible to erosion and the loss of land to the encroaching sea.
The land formed when softer rock is eroded by the sea is called a coastal cliff or coastal bluff. These landforms are typically found along the coastline where the waves have worn away the softer rock layers, leaving behind more resistant rock formations as cliffs or bluffs.
Hard rock, an example of soft rock is Barton-on-sea.
The rocks get eroded away by the sea, and then, after a lot of eroding a hole is formed in the rock, which is called a cave. After a bit more eroding the sea will eat right through the rock and make an arc.
Sea caves form by ocean waves pounding at the base of seashore cliffs.
Durdle Door was formed by erosion of the soft rock. The sea eroded the soft rock until it reached the limestone where it couldn't erode it leaving an arch.
Sea cliffs composed of clay or chalk are susceptible to erosion and the loss of land to the encroaching sea.
Coves formed where rock runs in bands horizontal to the direction of the waves. There is a band of resistant rock closest to the sea and a band of less resistant rock inland. The wave seeks out faults in the hard rock and erodes through to the soft rock behind. Then the Wave eroded the softer rock faster and this leaves a circular cove with a narrow entrance where the sea enters.

Over millions of years, the piled weight of eroded particles will squeeze the bits together on the sea floor. New rock will form

Chalk is a hard rock, with large lines of weakness so will erode by physical weathering and the sea.
