Reef. A reef is a ridge or shoal of rock, coral, or similar relatively stable material lying beneath the surface of a natural body of water. [1] Many reefs result from natural, abiotic (non-living) processes such as deposition of sand or wave erosion planing down rock outcrops. However, reefs such as the coral reefs of tropical waters are

Coral reefs take four principal forms. (1) Fringing reefs consist of flat reef areas that directly skirt a nonreef island, often volcanic, or a mainland mass. (2) Barrier reefs are also close to a nonreef landmass but lie several kilometres offshore, separated from the landmass by a lagoon or channel often about 50 metres (160 feet) deep.

A coral reef is an underwater ecosystem characterized by reef-building corals.Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish.Unlike sea anemones, corals secrete hard

Coral reefs are at the center of many coastal and island cultures around the world. For example, in the Kumulipo, the Hawaiian creation chant, the coral polyp was the first organism created, and from that all other life forms sprung forth. Though coral reefs face numerous threats, we can save them by keeping them healthy.

Coral reef - Marine Ecosystem, Formation, Diversity: English naturalist Charles Darwin concluded in 1842 that barrier reefs began as reefs fringing the land around which they now form a barrier and that oceanic atoll reefs began as reefs fringing a volcanic island. Subsidence of the land fringed was thought to allow the reef to grow upward (and outward over its own fore-reef debris).

Coral reefs are made up of tiny organisms that link together. The reefs get their color from the algae that live inside them and are the corals' food. When temperatures get too high, the coral expels the algae, making the reefs appear white or bleached. That doesn't mean they are dead, but the corals can starve and are more susceptible to
