Barrier Islands

Real World Example

Imagine walking with an umbrella on a windy day, trying to shield yourself from the gusts. Just as the umbrella protects you from the wind, barrier islands act as a shield for the mainland coast, taking the brunt of the ocean's energy and protecting the inland areas from erosion and storm surges. The umbrella is to you as the barrier island is to the mainland; both serve as a protective layer, absorbing external forces and maintaining a calmer environment behind them.
