Coastal Erosion

Exam Question Referring to a stretch of coast, explain the factors that invite led to this coast suffering from erosion (10 marks) Many factors mate off led to erosion on the Holderness coast, in northmost eastern United States England. These may call for been processes that shoot been winning a while, or something that occurs suddenly. There atomic number 18 three briny reasons for the rapidly gnaw coastline at Holderness; the geology, the fetch and longshore drift and land material. The Holderness Coast is mainly two rock types; chalk and bowlder clay. Chalk is plumb resistant and at places equal Flamborough Head, it finds features much(prenominal) as cliffs, caves, arches and stacks. bowlder Clay is fairly weak and loose; but it is actually good and fertile for arable farming. bowlder clay, also cognise as glacial till, is a intermixture of clay and sands, which have been left from glaciers. Holderness is exposed to wind and waves from the north-east, w hich have a diminutive fetch of about 500-800 km crossways the North ocean. This is not far, compared to some of the worlds large-mouthed oceans, but the surface of the waves attacking the coast is increased by four opposite factors. One is the currents or swell, which circulate more or less the UK from the Atlantic and into the North Sea. The Atlantic fetch is 5000 km or more, and its currents add push to waves in the North Sea.

Therefore, there are often decent destructive waves along the coastline, eroding the cliffs. The split second point is the gloomy pressure weather systems passing everyplace the North Sea are often intense, and locally produce very hefty winds and waves . Thirdly; small, almost enclosed seas, an! alogous the Mediterranean or North Sea, often generate coarse waves during storms. Waves move within the sea but cannot disperse their cypher rather like water slopping up against the side of a washbasin. Lastly the sea floor is deep along the coast. Therefore, the waves tint the cliffs without first being weakened by friction with shallow beaches. As a result of these four factors, waves along...If you want to loaf a beneficial essay, order it on our website: OrderEssay.net
