Cliff profiles owe their form to the geology (Lithology and structure), sub-aerial processes and wave energy along a given stretch of coastline. It takes thousands of years for the cliffs profile to form from complex processes, there are many complicated processes taking place on coasts that affect the profile of a cliff. Wave action causes three erosional processes, abrasion, hydraulic action and corrosion. These processes are most effective when high energy waves, associated with storm …showed first 75 words of 549 total…

However human activities such as mining may accelerate erosion. The forming of cliff profiles takes a long time and the processes are complex. There are many factors needed for the processes and if the factors weren't available then the processes wouldn't be able to take place and form the cliffs profile.
