Graphic explaining cliff retreat

By Geology and Ecology of National Parks
A digitally illustrated explanation of cliff retreat. A cliff with a protruding bottom is bombarded with wave erosion. This causes the cliff to flatten (the top and bottom are equally protruding). As wave erosion continues, the bottom erodes more than the top and eventually the top becomes to heavy and falls into the ocean. Then the process begins again.
