If you go to a beach in the continental United States and you are standing on a long, flat strand of sand, and you look away fro
m the open ocean and see only a few low sand dunes and then a large, open waterway, where are you? A. on a surfing beach in California B. on a the Oregon coast at the mouth of river C. on a barrier island D. on the Florida Gulf Coas
A barrier island is usually defined as a long and narrow type of land that is dominantly comprised of sand particles and are oriented parallel to the coastal mainland.
The presence of a barrier island protects the coastal rocks from getting eroded by the strong water waves, wind, and tidal effects. This acts as a barrier and there lies a lagoon between the coastal landform and the barrier island.
It plays an important role in the ecosystem as it provides valuable nutrients and minerals, supporting a large number of living species.
