Using a coastline that you have studied assess the impacts of Geology on nature and rates of erosion, the landforms produced and the type of beach sediments.
Rock type affects the general nature of cliffs as they can be different heights and forms depending on the rock type of the coastline. Hard rock cliffs (such as granite) can withstand much greater rates of erosion and pressure from the coastal processes, whereas soft rock (such as marl, which is a type of clay) erodes much more easily and quickly. ... Langstone headland has been formed as there are alternating bands of marl and sandstone along the coastline and due to the marine and sub-aerial processes acting on the coast, a band of sandstone, the more resistant rock, has been left as an outcrop. ... of the headland as the sandstone is not protected by the sand, meaning marine process have much more effect on the coastline. ...
The geology of the coastline is the most important factor that affects the rates of erosion and landforms along the coast. ...
Human factors can help protect certain areas of coastline whilst damaging others, for example groynes are used to prevent longshore drift carrying sediment along a coastline. However other areas further down the coastline suffer as sand protects coasts from severe erosion, therefore when they are deprived of sand, levels of erosion increase dramatically.
