What is the difference between an island and an atoll?

An atoll is formed from an island, but it isn't entirely an island. It's a coral reef that makes the different. The reef grows in a ring around the island and the island erodes, until little if any of it is above the surface of the water and the coral reef remains. Islands are any small body of land surrounded by water. Islands in the middle of the ocean are usually volcanic and islands in lakes and near continents are usually just areas of the continental shelf surrounding the continent with a higher elevation. To actually answer your question, the KEY difference is the reef.


What is the weather like on coral island?

The weather on a coral island can vary, but generally it is warm and tropical with plenty of sunshine. Rainfall can be sporadic, with some coral islands experiencing wet and dry seasons. Wind patterns and ocean currents can also influence the weather on coral islands.


Give you an example of an atoll?

An atoll is formed first as a reef that fringes a volcanic island. As the island sinks (after the volcanic activity has ceased and the crust has cooled, becoming denser), the reef continues to build upward, eventually ending up as a ring-shaped structure.

An atoll is a ring-shaped coral reef island that encircles a lagoon partially or completely.
