Because of this, temperatures in Britain do not fall in winter to the levels experienced by cities at the same latitude elsewhere in Europe. On a smaller scale, local currents have an effect on the coastline, causing regular erosion, deposition and transportation of beach materials. Over the years the current has built up a spit such as that at Blakeney in north Norfolk, moved Spurn Head in Lincolnshire and removed the materials eroded from the cliffs at Covehithe in Suffolk. Erosion Erosion is the process of changing the coastline through geomorphological processes - the changing of the form of the land. Attrition takes place when small pieces of rock rub against each other and wear themselves down into smaller rounded stones.
Corrosion takes place when the salt water of the sea dissolves the mineral in some forms of rock.
Hydraulic action causes air, trapped by waves as they break against a cliff, to force open the cracks and in the course of time the rock breaks away.
