Coasts - Formation of Coastal Features

Question 1

explain the six-stage process by which caves, arches, stacks, and stumps are formed

Answer 1

the sea erodes lines of weakness in a headland through HA, A, S, to form a sea cave, Sea caves on either side of the headland deepen and widen until the sea erodes through the headland to form an arch, Arch deepens and widens causing the top part to become unsupported and collapse forming a stack, Stack erodes down to form stump, Stump erodes and disappears, Headland retreats back over time
