A barrier island is a long ridge of sediment deposited by the longshore current and separated from the mainland.

Step-by-step explanation;

• A barrier island is a long, thin, sandy stretch of land that is oriented parallel to the mainland coast. The barrier island protects the coast from the full force of powerful storm waves.
• The barrier islands are very important as they protect the mainland from storms and waves. Additionally, they protect tidal lagoons that serve as nurseries for a variety of fish and shellfish.
