An atoll is an island formed from a coral reef that has grown on an eroded and submerged volcanic island. The reef rises to the surface of the water and forms a new island. Atolls are typically ring-shaped with a central lagoon. Examples include the Maldives in the Indian Ocean and Line Islands in the Pacific.
• Tropical islands
There are approximately 45,000 tropical islands on Earth. Among coral tropic islands for example are Maldives, Tonga, Nauru and Polynesia. Granite islands include Seychelles and Tioman. The socio-economic diversity of these regions ranges from the Stone Age societies in the interior of Madagascar, Borneo or Papua New Guinea to the high-tech lifestyles of the city-islands of Singapore and Hong Kong. International tourism is a significant factor in the local economy of Seychelles, Sri Lanka, Mauritius, Réunion, Hawaii and the Maldives, among others.
