Headland

A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water.

[1] Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff.

Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast.

Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula.

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.
