How are barrier beaches formed?
Barrier Beaches are dynamic strips of coastal dunes and beaches that are formed by long shore currents depositing sand across the mouth of an inlet or harbor. Barrier beaches are divided into frontal beach, dune, and inland beach, usually with a marsh or estuary system in the sheltered zone behind the barrier.
These beaches are extremely dynamic systems that are constantly subjected to wind and wave energy. Well-vegetated areas on the barrier are somewhat stable, but sandy areas migrate significantly and large storms can rip holes right through the barrier. Inland areas are buffered by the barrier beaches, which dissipate storm wave energy by their shifting sands.
Barrier beaches provide nesting sites for certain rare species of birds including piping plovers (Charadrius melodus) and roseate terns (Sterna dougallii).

Any structure, whether a house or a jetty, that impedes the movement of a barrier beach will cause undesirable changes in the beaches ability to dissipate wave energy. No structure is permanent if built on a barrier beach.

The major reason that beaches differ so much is due to the nature of the material from which they are formed: black beaches are often formed from volcanic rock that is black in color, white beaches are often formed from fragmented coral, muddy beaches may be the result of fine sediments washing down from land or from fine textured offshore deposits. The wave energy will influence the texture. Sandy beaches occur in higher energy environments… Read More

beaches are formed anywhere where the ocean is in contact with the shore. Beaches form as waves deposit sand and other sediments and it collects and it rebuilds itself everytime a wave tides. Read More

Some beaches are "groomed", meaning that man has come through and removed the rocks, or brought in sand. However, most beaches are formed from the waves grinding the rocks down into sand. Read More
It is coral in the Great Barrier Reef, not rocks. But the coral was formed from the rise and fall of the ocean thousands of years ago, during the final years of the Ice Age. Read More

Beaches form when tiny bits of rock that have been eroded by the action of the waves wash up on shore. They are different because they tend to be composed of different types of sand (rock bits). For example, beaches formed mainly of lava rock will have black sand, while other beaches may be white, pink, or tan. Read More
The great barrier reef was formed AFTER the ice age so it never froze. The great barrier reef lives in a tropical area, which means there is only rain and sun. So, the great barrier has most likely never been frozen. Read More
