Overall, while the erosion reveals a significant impact on the headland, the coastline remains unchanged.At one time, a small hollow in weak areas is constructed by the sea water which hit the wall. After long process, the hole is being bigger than before creating cave's arch. This is because the waves touch the wall's cliff. What is more, even though such waves always beat the cliff, it develops a new big cave and separated stuck as a result of hitting against roof. This means that stones and boulders fell into the sea and side of separated headland.Eventually, this natural process creates a new cave and huge stack, whilst the headland becomes more retreated and dangerous. Meanwhile, another stack is made by such waves' hitting and its stumps fell down to coastline. In fact, this worrying condition happened in Durdle Door, Dorset. Obviously, had the cliff not been beat by the waves, the headland's existence would not have been threatened.
