A coral atoll is a ring-shaped coral reef or island found in warm, tropical oceans. They are formed from the accumulation of coral skeletons on the rims of submerged volcanic islands over thousands of years. Atolls typically enclose a lagoon in their center.
At the center of an atoll is usually a lagoon, which is a body of water surrounded by a ring of coral reef. The lagoon can vary in size and depth depending on the specific atoll.
A grouping of coral islands is called an atoll. Atolls are formed from coral reefs that have grown on the remnants of volcanic islands that have sunk in the ocean. They usually form a ring shape with a lagoon in the center.
An Atoll is the name used to refer to a group of related coral islands.
An atoll is formed from an island, but it isn't entirely an island. It's a coral reef that makes the different. The reef grows in a ring around the island and the island erodes, until little if any of it is above the surface of the water and the coral reef remains. Islands are any small body of land surrounded by water. Islands in the middle of the ocean are usually volcanic and islands in lakes and near continents are usually just areas of the continental shelf surrounding the continent with a higher elevation. To actually answer your question, the KEY difference is the reef.
