Atoll

An atoll is a ring-shaped coral reef that encircles a lagoon, often rising from the seabed in the open ocean. These unique formations are created over long periods, beginning with the growth of coral around a volcanic island. As the island slowly subsides, the coral continues to grow upwards, eventually forming a ring with a shallow lagoon at its center. Atolls are typically found in tropical and subtropical waters and support diverse marine life. Their picturesque beauty makes them popular destinations for tourism, but they also face threats from rising sea levels and climate change.
