A headland is an area of hard rock which sticks out into the sea. Headlands form in areas of alternating hard and soft rock. Where the soft rock is eroded bays form either side of the headland. As the headland becomes more exposed to the wind and waves the rate of its erosion increases. When headlands erode they create distinct features such as caves, arches, stacks and stumps.
The diagram below shows the sequence in the erosion of a headland.

Stage 1 in the formation of a headland
Waves attack a weakness in the headland. The video below shows cracks in the chalk cliffs at Flamborough.
Stage 2 in the formation of a headland
A cave is formed.
Stage 3 in the formation of a headland
Eventually, the cave erodes through the headland to form an arch.
The base of the stack is then eroded which causes it to collapse leaving a stump.
The erosion of a headland is explored in more detailed below.
