Quizplus · Accepted Answer

Barrier islands are offshore sandbars that form due to abundant sediment supply and sit above the mean high water level. Marine terraces are broad, flat, elevated coastal landforms that form as a result of wave erosion over long periods of time. Coral reefs are underwater structures made from calcium carbonate secreted by corals. Estuaries are semi-enclosed coastal bodies of water where freshwater and saltwater mix.
