Summary

Our coastlines are dynamic and influenced by erosion, deposition, and a changing sea level. These processes can be caused by wind, waves, and longshore currents. The formations that result include beaches, dunes, rocky headlands, arches, islands, bays, spits, and lagoons. People have tried to modify the formation of these structures through jetties, seawalls, and numerous other manmade structures.
