Islands like St. George Island and Dog Island are common along all coastlines in Florida (Merritt Island is another example). Identify the coastal feature that these islands represent and describe the formation process of these islands.

These islands are barrier islands.

Explanation:

Barrier islands are islands in front of the mainland that separate part of the sea from the open sea. They lie parallel to the coast and have an elongated, narrow shape. On the sea side, dunes often shape the surface, on the land side they are flat. They were created by deposits of waves, currents and wind. Their formation requires a shallow coastal fore, a sufficiently large sediment store and a weak to moderate tidal range.
