Headland: A point of higher land jutting out into the sea, usually made of a resistant rock. (e.g. Granite)
Bay: Part of the sea that fills a wide-mouthed opening in the coastline

How do Headlands Form?
Headlands are formed when the sea attacks a section of coast with alternating bands of hard and soft rock.

The bands of soft rock, such as sand and clay, erode more quickly than those of more resistant rock, such as chalk. This leaves a section of land jutting out into the sea called a headland . The areas where the soft rock has eroded away, next to the headland, are called bays. The headland now takes the full force of the waves, and they are refracted, so the bays are sheltered, from the destructive waves.

Examples of Headlands and Bays?
Along the coastline of the Isle of Purbeck in Dorset. The coastline has been formed into Studland Bay (soft rock), Ballard Point (hard chalk rock), Swanage Bay (soft clay rock) and Durlston Head (hard rock).
