The diagram shows the changes that took place in a headland as a result of rock erosion and how this led to the formation of stacks and stumps. Clearly, the headland would have remained unchanged if it had not been influenced by the action of the sea.
At one time, the waves hit the lower part, where was the weak area of the headland, resulting in this area being eroded and turning into a cave. Meanwhile, the sea water passing through along with the waves hitting the cliff at the top of the cave frequently made this place become an arch like Durdle Door, Dorset, some of the most popular arches in the world. Through time, at high tide, these waves reached the roof stack and beat on it with some force. This meant that rocks and boulders fell into the sea, and at some point the arch was collapsed completely and formed a stack, which was separated from the headland by the sea. The headland had kept retreating to create another stack. At the same time, the old stack was cracked and eroded more quickly by the wind then fell down and become a stump.
