How are corals formed?

उत्तर
Corals are a hard substance composed of a skeleton of tiny marine creatures called coral polyps. When corals die their hard skeletons remain fixed in place. Since these polyps live in colonies when they die their large accumulation of skeletons forms coral reefs which are circular or ridge-like.
