Barrier Islands

By: Shania T. Jones

The Barrier Islands is a type of barrier system. It is a coastal landform and are relatively narrow strips of sand that are parallel to the mainland coast. They can be grouped into three major theories: offshore bar theory, spit accretion theory, and submergence theory. Most barrier island in North America are along the Atlantic and Gulf Coast. Georgia's barrier islands are actually the midsection of a system of oak-shrouded, sandy barriers that extend from the middle of the South Carolina coast to the mouth of the St. Johns River in Jacksonville, Florida.
