How can an island with fringing reefs become atoll?
An island with fringing reefs can become an atoll through a process known as subsidence. As the volcanic island gradually sinks due to tectonic activity or erosion, the surrounding coral reefs continue to grow upward toward the sunlight. Over time, the island may completely submerge, leaving a lagoon surrounded by the coral reef, thus transforming the fringing reef into an atoll. This process can take thousands to millions of years.

How is an atolls formed?
Atolls are formed from coral reefs that grow on the rim of a submerged volcanic island. Over time, as the island gradually sinks and erodes, the coral reef continues to grow upward, eventually forming a ring-shaped coral island with a lagoon in the center. This process results in the formation of an atoll.
Atoll actually start as a what?
Atolls actually start as fringing reefs that grow around volcanic islands. Over time, as the volcanic island erodes and sinks, the coral reef continues to thrive and grow upward, eventually forming a ring-shaped structure that surrounds a lagoon. This process can take thousands to millions of years, resulting in the characteristic atoll formation seen today.
What are the different forms of coral reef?
Coral reefs can take four forms; fringing reef, platform reefs, barrier reefs and atolls. Fringing reefs are narrow and shallow, and generally occur near the shore, they literally are a thin 'fringe' along the coast. Platform reefs are reef outcroppings far from shore that occur in calm water. They often have a shallow lagoon, and are flat on top. Barrier reefs are reefs growing along a coastline that are separated from the coastline by a lagoon. Barrier reefs are very similar to fringings except that they are much larger. Atolls are ring reefs that usually form at the base of a volcano. Over time the volcano dissapears, leaving a rin of reef surrounded by deep ocean.

What island is build from coral that forms on the flank of sinking volcano?
The island that is built from coral that forms on the flank of a sinking volcano is called an atoll. Atolls are usually ring-shaped islands formed from coral reefs that grow around the submerged crater of a volcano. Over time, as the volcano sinks, the coral continues to grow upwards, creating a circular or oval-shaped island.
