The differing resistance to erosion leads to the formation of headlands and bays. During the Devensian Glacial eustatic changes lowered sea levels by 120 m. At the start of the Holocene Interglacial (10,000 years BP) led to a rapid 100 m eustatic rise in global sea levels, as 3,000 years of ice sheets and glaciers shrank. Either way, there is now a (bit of) coastline that is no longer submerged under water. - Headlands form along discordant coastlines in which bands of soft and hard rock outcrop at right angles to the coastline.
