2. What is the formation theories?Emergent offshore shoals, spit accretion, submergence of coastal ridges
3. Why do barrier islands protect the mainland?They act like a shield, soaking up the energy of waves and storm surges so the water that reaches the shore is gentler and less likely to erode the land.
4. How do barrier islands change over time?They move and grow as wind and waves move sand, and storms can push sand from the ocean side to the land side, making the island shift toward the mainland.
