The document discusses different types of weathering and erosion processes that shape coastlines. Waves erode softer rock faster than harder rock, forming bays surrounded by harder headlands that are more resistant to erosion. Deposition occurs in the sheltered bays, creating beaches, while the exposed headlands continue to be eroded by waves. Biological, chemical, freeze-thaw and other processes also contribute to coastal weathering and erosion over time.

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

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