What are barrier islands, and where do they form? How does the sand migrate on barrier islands? What will be an ideal response?
Barrier islands are long, narrow islands of sand, lying a short distance offshore from the mainland.
They form on gently sloping continental shelves where sand is abundant and wave energy and tidal
range are low. The sand of most barrier islands is migrating landward as sand is eroded from the
seaward side and deposited on the landward side.
