The stages in the erosion of a headland

The diagrams entirely illustrate total phases of transformation in the erosion process of a headland as a result of the coastal impact, simultaneously, how both stack and stump are generated. In the preliminary stage, the headland has been still solid and connects to the mainland. At the bottom, weak zones were affected and loosened gradually by ocean waves created a hole. In the course of time, wave forces beat against the weak areas to become a cave as a below tunnel via the headland. In the next stage, as the contact zone of the cave widened out, wind and tide had more chances to stimulate the erosion process accelerando. Eventually, the previous one transformed into an arch looking like a parabolic line often called Durdle Door or Dorset. At high tide, the roof cavern collapsed by powerful strikes of surged waves. After the arch’s ruin, the whole headland is separated into two pieces comprising of a stack of earth and the rest. At the end of the diagrams, the process continued to keep a fast pace induced by both coastal erosion and weather. The collapse of the stack of land left made a stump. Although the water did not touch the up of the headland, it also perceived the retreat caused by weather consisting of wind, sun, etc.
