What are the air masses that affect the UK? 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.

This material will then be carried away by the sea in the process of long shore drift by the transportation process of solution, suspension, saltation and traction (depending upon the particle sizes). cave forms in a headland, it may break through causing an arch to form. This is particularly pronounced where hard rocks, e.g. Eventually, the continuing erosion will lead to the collapse of the . Created steep cliffs (e.g Peveril Point) .

Where are polar and tundra environments located? What are the examples of coastal landforms? It is this soft boulder clay that is being rapidly eroded. Wave refraction concentrates waves on the headland allowing caves to develop progressively into arches, sea stacks and stumps. How has demand for water in the UK changed? Then please contact us with your suggestions and comments so that we can improve our website further. Arches - caves continue to erode until they break through the headland creating arches.
