Faults have developed into caves some of which have eroded through into arches. At places on the cliffs where the chalk juts out, these caves are worn away into rock arches. This is called hydraulic action, and this force will erode the crack to such a point that it becomes a cave. Caves, arches, stacks and stumps sequencing An interactive approach to the formation of caves, arches, stacks and stumps.

You can also encounter Cheddar Man, Britain's oldest known human skeleton. This creates an archway, hence the name, in the middle of a headland. The headland juts out into the sea, so it is more vulnerable to high-energy waves. This leaves a headland with a column of rock separate from the mainland, this is a sea stack. Stumps - wind. This nasty character often made life difficult for St Patrick, who prayed regularly at the church on Downpatrick Head. Waves attack vertical lines of weakness in the rock known as Faults. The cave will give way and the water will drill its way on through the back of the cave, thus creating an arch. Maiden Stack is the islands tallest sea stack, named after the daughter of a Norwegian Lord supposedly imprisoned there for refusing an arranged marriage.

Cracks are formed in the headland through the erosional processes of hydraulic action and abrasion. Headlands are normally made of resistant rock which do not erode easily, but cracks can develop into caves, arches and stacks. Transportation and deposition. A large hole in a cliff. The area below the crack or joint is undercut and a small cave will form. The crack is then deepened and widened over time due to hydraulic action and corrasion. .

These features are formed on cliffs or headlands. This answer is: Helpful ( 1) Not Helpful ( 0) Add a Comment. How are caves, arches, stacks and stumps formed? 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.
