Coastal Features Headlands and Bays A headland is an area of land which juts out to sea and is surrounded by sea on three sides. Headlands form in coastlines.

Coastal Regions. Waves cause coastal features such as Arches, Caves and Inlets. Headlands (shorelines that project into the ocean) erode much faster compared.

A coast is the edge of the land where it meets the sea or ocean

BAYS AND HEADLANDS

Features of Coastal Erosion: Headlands and Bays Waves attack the coastline. Harder rock Softer rock Harder rock

The softer rock (clay or sand) is eroded by the sea- forming a bay. This area is now more sheltered, this encourages deposition and beaches are formed. Harder rock Harder rock The softer rock (clay or sand) is eroded by the sea- forming a bay. Softer rock The more resistant rock (limestone or chalk) is left sticking out into the sea called a headland. Harder rock

The shallower waters in the bay continue to encourage deposition. Surrounded by deep water and exposed to the full force of the waves- the headlands are eroded. Harder rock Harder rock The shallower waters in the bay continue to encourage deposition. Softer rock Harder rock
