Coastal processes of erosion include hydraulic action, attrition, corrosion and solution. This small network of caves is located between Botany Bay and Kingsgate Bay. The base of the stack receives a lot of erosion from hydraulic action and corrosion and, eventually, the stack will collapse into the sea leaving behind a small piece of land called a stump. These processes widen these weaknesses into cracks, which slowly become larger and develop into small caves. Wiki User.

Arches: where a cave has eroded through a headland or curtain of more resistant rock. 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. Oxidation and carbonation are some of the chemical processes that can weaken the structure of the rock, and depending upon the climate physical processes such as freeze thaw and water layer weathering can take effect. Waves attack vertical lines of weakness in the rock known as Faults. Where are the areas of water deficit and surplus in the UK?
