Other Features: Sea Caves, Stacks & Arches These are formed in rocks that have a fault or line of weakness. The action of the sea will exploit the fault, through erosional processes such as hydraulic action. In time the fault will widen to form a cave. If the fault is in a headland, caves are likely to form on both sides. When the backs of the caves meet, an arch is formed. The sea will continue to erode the bottom of the arch. Weathering will also take place on the bare rock faces. As the sea undercuts the bottom of the arch, a wave-cut notch will form. It will collapse in time, as it is pulled down by the pressure of its own weight and gravity. This leaves behind a column of rock not attached to the cliff, known as a stack. Continued erosion and weathering will lead to the formation of a stump that is visible only at low tide. lines of weakness 19. Blowhole 20. Sea Stack postpontaal 21. Sea Stump 22. Sea Arch 23.
