Headlands and bays
Areas of the coast which have soft rocks are worn away more easily than those with hard rocks. The soft rock areas become bays and the hard rock areas become headlands. A bay is an opening in the coastline, whereas a headland is a stretch of land jutting out to sea.

Dorset coastline
The Dorset coastline has changed because of it’s different geology. The area in the SW at Durdle Door has eroded...

The waves attack the base of the cliff through the processes of
corrasion, attrition, solution and hydraulic action.
Over time the cliff will be undercut and a wave-cut notch is formed.
Eventually the cliff becomes unstable and collapses. Further cliff
retreat will form a wave-cut platform, which is made smooth by the
sea.

Is it a good time to go rock pooling after a period of stormy weather? Explain your answer.
Challenge question:
Why do sandy beaches have gentler sloping beaches compared to shingle and pebble beaches?

Coastlines where the geology alternates between strata (or bands) of
hard rock and soft rock are called discordant coastlines. A concordant
coastline has the same type of rock along its length. Concordant
coastlines tend to have fewer bays and headlands.
