They retreat backwards

Less resistant rock and exposed resistant rock causes a change in shape of coastline

Q

What does the change wave approach effect?

A

It increases the rate of erosion on headlands
This creates headland features
caves, arches, stacks and stumps

Q

True or false? do bedding planes that dip towards the sea have a gentler cliff profile?
