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 ( feet) deep. Some. Coral reefs are unique ecosystems of plants, animals, and their associated geological reefs cover less than percent of the earth's surface, but are home to an estimated 25 percent of all marine species.
Second only to tropical rainforests in size and complexity, some scientists estimate that more than one million species of plants and animals are associated with coral reefs. coral reefs, volcanic islands, south american geology.

A coral reef is an underwater ecosystem characterized by reef-building are formed of colonies of coral polyps held together by calcium 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 sea anemones, corals secrete hard carbonate. In geology (and sometimes in archaeology), a high island or volcanic island is an island of volcanic origin. The term can be used to distinguish such islands from low islands, which are formed from sedimentation or the uplifting of coral reefs (which have often formed on sunken volcanos).

Darwin proposed that volcanic islands with fringing reefs, islands with barrier reefs and atolls (i.e. ring-shaped reefs without a volcanic island) are different stages of one process, controlled.
