The differing resistance to erosion leads lulwworth the formation of headlands and bays. At the back of the cove is a band of more resistant chalk, so erosion is slower here. The arch is gradually being worn away by mechanical, chemical and biological weathering.

The bands of soft rock erode more quickly than those of the more resistant hard rock leaving a section of land jutting out into the sea, called a headland.
