Question

Quizplus · Accepted Answer

Barrier islands are formed by the accumulation of sedimentary materials parallel to the coastline, and they are constantly in motion along the direction of the longshore drift, which is the movement of sediment caused by waves moving to the shore at an angle. As waves approach the shoreline obliquely, their energy is concentrated along the shore and generates currents that move sediment along the coast in a zigzag pattern. This movement of sediment causes the barrier islands to migrate landward over time.
