Barrier Islands are constantly changing because of their location, acting as a buffer to the mainland. They change over time due to fluctuations in tides, differing strengths in ocean waves and the shifting and movement of sand. With the erosion of the land on the barrier islands, they often appear to move or migrate towards the mainland.
