Caves, arches, stacks and stumps are usually found on headlands, where wave refraction is causing erosion on three sides. 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. a) Study the photograph, IMAGE 3 and add explanatory labels and captions. As the coast suffered hydraulic action, caves and arches were formed; the tops of the arches then weakened and collapsed, leaving disconnected stacks. United Kingdom - Durdle Door, Green Bridge of Wales, Bow Fiddle Rock. These regions are characterized by beaches, dunes, barriers, deltas, strandplains, backbarrier marshes, lagoons, and tidal flats.

Once the cave has formed, the waves are able to enter and continue eroding back into the headland until they eventually break through to form an arch (for example Durdle Door, Dorset, UK) In time the base of the arch is attacked by the waves and this puts increasing pressure on the roof of the arch. Processes such as hydraulic action and abrasion widen these faults into cracks and eventually the waves will penetrate deeply enough to create caves. Studying in the UK; Studying abroad; Studying business and management; University. An example of this are caves, arches, stacks and stumps. Best Answer.
