Corrasion is where materials in the waves are smashed against the rocks eroding/ breaking them up. The constant battering by powerful waves on sea caves or arches causes the unsupported rock above to collapse under its own weight. Stumps. Sea Stump. These processes are variable and depend upon the fetch of the wave (the distance it travels over open water), wind speed and how many storms there a year, but they are more or less continuous over long periods of time. Weathering will also play a role, with physical weathering processes such as freeze thaw and salt crystallisation and chemical processes such as carbonation weakening the rock surrounding the cave or arch making it more susceptible to mass movement and collapse. and caves, arches, stacks and stumps Explain the formation of the following coastal deposition landforms; beaches, sand dunes, spits and bars Use a real-life example (Swanage) to show how coastal erosion and deposition shape a coastline Explain how the following hard engineering flood protection methods a) Study the photograph, IMAGE 3 and add explanatory labels and captions.
