Erosional vs. Depostional Coastlines


I found this great diagram illustrating the differences between an erosional and a depositional coastline. Depositional coastlines are formed by the gradual building up of sediment. Erosional coastlines are obviously products of erosion. Topography, prevailing winds and ocean currents, and geology are all factors that determine the nature of a coastline. The BBC Scotland education section has a few good pages about coastlines here. Image source here.
