The Maldives consists of just over 1,900 small islands spread out over 90,000 square kilometres. Geographically, the majority of these islands are best described as what type of islands?

The Maldivian islands are coral atolls formed from coral growth on submerged volcanic mountains. These coral formations create ring-shaped reefs with central lagoons, characteristic of atoll islands. Unlike volcanic islands formed by eruptions, coral islands are built by living organisms over thousands of years, making the Maldives the world's largest coral atoll nation.
