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.
