What do you think the origin of the broad, flat surface is above the coastal cliffs shown below?10/26/2023 However, deposition is a lot more complex than this and it is important to develop a structure that puts the emphasis on place and scale. They tend to overlook less obvious, but equally important features, for example, the beach. When students think of coasts of deposition they are immediately drawn to discuss the processes of long-shore drift and the formation of spits. In this way you nnot only have to identofy varying rates within headland and bays, but you should also be thinking of ocean fetch, exposure, geoology and sub-aerial processes. At Post 16 the question you should expect will be one that focuses on rates of erosion. It also introduces a greater complexity of processes. This shows how vocabulary is used to exemplify. The second diagram shows a Post 16 model example. It also shows the sequence through numbering. The diagram below left, shows a well annotated headland, (at the (I)GCSE level) and it explains how headlands erode over time. There isn't a great deal of complexity in understanding and explaining how the features develop over time but clear exemplification is required as well as a clear sequence. ![]() In Geography, the erosion of headlands in developing the sequence of cave to stumps is well developed, but how is it extended at the Post 16 level. ![]() In doing so, quite distinct features develop. As a result of wave refraction, destructive waves concentrate their energy on all three sides of the headland and so it slowly erodes overtime. Headlands, once formed, are exposed to the full force of the sea.
