atoll
An atoll is a ring-shaped coral island or string of islands that surround a lagoon. Atolls typically form from volcanic islands that sink into the ocean, leaving a coral reef formation around the edge of the submerged island. The lagoon in the center of an atoll is often shallow and can support diverse marine life.

Atolls are ring-shaped coral reefs, often found in the open ocean and surrounding a lagoon. They form from the growth of coral reefs around a submerged volcanic island that erodes over time, leaving a ring of coral islands. Atolls are typically found in tropical areas with warm, shallow waters.
Atoll
Atoll. Atolls are oceanic reef formation, often having a characteristic ring-like shape surrounding a lagoon. Atolls are formed when coral reef grows around a volcanic island that later subsides into the ocean.
An atoll is a ring-shaped coral reef, island, or chain of islets surrounding a lagoon partially or completely. Atolls are typically found in warm, tropical oceans and seas, often in the Pacific and Indian Oceans.
An atoll typically forms a ring-shaped structure, consisting of a coral reef encircling a lagoon. This formation occurs as coral grows around the rim of a submerged volcanic island, which eventually erodes away. The result is a circular or oval formation with a central lagoon, often characterized by shallow waters and rich marine biodiversity.

An atoll is formed first as a reef that fringes a volcanic island. As the island sinks (after the volcanic activity has ceased and the crust has cooled, becoming denser), the reef continues to build upward, eventually ending up as a ring-shaped structure.
Another name for a low-lying island is an atoll. Atolls are circular or oval-shaped coral reef formations that surround a lagoon partially or completely.
