The diagram below show the stages in the erosion of a headland. Summarize the information by selecting and reporting the main features, and make comparisons where relevant
The pictures illustrate how a headland can be eroded by wave in the coastal area and how the surface of hard rock can be changed. Overall, it is interesting to notice that even though the wave is quiet enough, it effects on the surface of a headland, and wear the headland down naturally without human activity.
Firstly, the first process is destruction of particular part of headland, especially in weak area will be eroded because of wave strength and then the small cave will be created. The small cave is bigger and bigger in size, so that it becomes natural arch. It likes Durdle, Door, and Dorset.
The further process, sea water hits the arch roof regularly. As the consequence, the roof stack falls into the sea level and the headland is separated and becomes small headland called stack. Afterward, the sea water still erodes the stuck and it is smaller and smaller. As a result, the small part of the stack exist opposite it, called stump.
