Geologic Features of Sandy Coasts

Depositional processes along coastlines, such as longshore sediment transport, form sandy beaches and create highly complex landforms that experience constant change and movement. Features such as spits, barrier islands, tombolos, and dunes are classic forms in sandy beach environments. Explore features of sandy beaches by selecting them from the diagram or images.
