barrier islands
Shore-shielding landforms
Barrier islands are long, narrow strips of sand running parallel to a mainland coast, separated from it by a lagoon or bay.
They form through wave action and sediment deposits, protecting the shore behind them from storms and erosion.
The Outer Banks of North Carolina are a well-known example.
These islands shift and migrate over time, making permanent development risky.
