Atollilla
Atollilla is a geographical term used to describe a type of coral island. It specifically refers to a ring-shaped coral reef that encircles a lagoon. Atolls are typically found in tropical and subtropical waters, often in the open ocean. The formation of an atoll is a complex process that begins with volcanic activity. A volcanic island forms, and as it subsides or erodes over time, coral polyps begin to grow on its submerged slopes. These corals build a reef structure around the island. As the volcanic core continues to sink, the coral reef continues to grow upwards, eventually forming a ring. The central lagoon is what remains of the submerged volcanic island. Atolls are often low-lying and are vulnerable to rising sea levels. Many atolls are home to unique ecosystems and are important for biodiversity. They are also inhabited by humans, who often rely on the marine resources provided by the lagoon and surrounding waters. The Maldives, a nation in the Indian Ocean, is a prominent example of a country composed almost entirely of atolls.
