In the given four pictures, the process of the erosion of a headland is illustrated. It is easily noticed that water could effortlessly destroy the whole headland, forming new constructions like stacks and stumps.
To begin with, in the first illustration, it is shown that the erosion starts from the weak areas, where the water fractures the rock. After that, the cave that was constructed by the force of the water becomes an arch, which is also could be named a Durdle, Door, and Dorset. Furthermore, from the second photo, there is another spot that starts to erode into the durdle.
Because of the waves that are hitting against a roof stack, the ach grows and eventually detaches the headland, while another “Door” starts to develop. In the end, the separated part is destroyed into small structures like stacks and stumps, where stacks are sharp rocks that point out of the water, and stumps are the remains of the stones. Moreover, the mainland is receding, which means that the previous position is not the same as it was before.
