Coasts - Headlands and Bays

The sea is responsible for the formation of Headlands and Bays accross our coastlines. Erosion in the form of Hydraulic Action and Abrasion from the sea’s waves pounds the coastline. Where there are areas of weaker rock such as sandstone and shale, the coast will erode faster. In areas where the rock is harder the coastline will erode more slowly. This difference in speed of erosion causes the formation of headlands and bays, particularly those that are found in areas such as cornwall.
