Headlands, once formed, are exposed to the full force of the sea. As a result of wave refraction, destructive waves concentrate their energy on all three sides of the headland and so it slowly erodes overtime. In doing so, quite distinct features develop.

What causes erosion along the headlands?

In areas where the geology or rock type runs at right angles to the coastline, bays and headlands can be created. ... Hydraulic action, abrasion and corrosion are more effective at eroding the softer rock, particularly during storms, and this will erode further inland than the harder rock.

Is a headland formed by erosion or deposition?

Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. ... Through the deposition of sediment within the bay and the erosion of the headlands, coastlines eventually straighten out then start the same process all over again.
