See image below for an example of a low cliff on the Suffolk coast. Eventually, the crack will enlarge and become a cave. Other shapes, such as (B), may be more susceptible to erosion. Marine erosion creates distinctive coastal landforms and contributes to coastal landscapes. the evolution of cliff profiles. Coastal Processes - The British Geographer Edexcel A Level Geography What are the environmental impacts of economic development in Nigeria? this is a type of mass movement. Over time cliffs retreat due to a combination of sub-aerial weathering and coastal erosion. Faults, joints, fissures and folded rocks, Major fractures in rocks produced by tectonic forces and involve displacement of rocks on either side of the fault line, Small scale coastal features such as caves and wave-cut notches which form part of a cliff profile. Mudflows occur on very steep slopes along the coastline. The angle the beds dip at affects how they are eroded and the profile of the resulting cliffs. If the bedding planes are flat (A), then the cliff shape will be consistent with a high cliff face. The soil continues to be lubricated and it eventually flows over the cliff face and down onto the shore at a fast speed. qcq%wFn+=#+ 0uEOr*cy_5{Lx_v @ @Me[k:]'fhk Sustainable development in the desert The Great Green Wall. Weaker rocks (e.g. Waves attack the base of the newly exposed rock faces. When the roof of the arch collapses a stack is formed(see image below). Which two characters are dominant? Sedimentary rock, such as the chalk cliffs located at Flamborough, Holderness Coast, are more resistant to erosion. Chalk surrounds the boulder clay. The boundaries of sediment cells are determined by the geography and state of the coastline. Often produce straighter coastlines. The angle the beds dip at affects how they are eroded and the profile of the resulting cliffs. Coastal cliffs in high latitudes are also characterized by relatively low gradients since the per glacial processes produce large amounts of cliff base materials.
