Describe how a coral atoll forms. What will be an ideal response?
A fringing coral reef forms around an island, usually a volcano. As the oceanic plate moves away from
the spreading center or volcanic hotspot, the plate cools and becomes less buoyant and sinks. The coral
continues to grow upward but the island erodes and disappears below the surface. The coral remains as
a circular atoll.
