What is atoll mean?

An atoll is a ring-shaped coral reef, island, or series of islets surrounding a lagoon. Atolls are typically found in the tropical and subtropical regions of the Indian Ocean and Pacific Ocean.

Atolls are formed when a coral reef grows around a volcanic island. As the volcano erodes and sinks, the coral reef continues to grow, forming a ring-shaped island. The lagoon inside the atoll is usually shallow and protected from the open ocean, making it a safe haven for marine life.

Atolls are important ecosystems that support a wide variety of marine life, including fish, corals, and sea turtles. They are also popular tourist destinations, due to their beautiful scenery and clear waters.
