Headland erosion is perhaps one of the best known processes in coastal erosion, where a crack in the headland is opened and enlarged by hydraulic abrasion. Rocky coasts may be composed of any rock type (i.e., sedimentary, igneous, or metamorphic) and are usually the site of complex tectonic landforms such as faults, folds, and igneous intrusions and extrusions. Waves approach the shore at some angle so the inshore part of the wave reaches shallow water sooner than the part that is further out. It is often a cliff or other elevated landform overlooking a sea or ocean. Bays can be formed in a variety of ways.

The sea erodes the softer rock faster than the harder rock, forming a bay. Over time, erosion can cause cliff collapse therefore the coastline needs to be managed. When there are different types of rock along a coastline, the weaker or softer rock, like clay, erode fastest leaving more resistant rock types such as granite, sticking out to create headlands. In lower-energy pocket beaches, sediment transport is not able to carry sediment downshore except during increased wave, wind, and storm activity.
