Atolls are coral islands. They have beaches made of coral sand, and perhaps a few palm trees growing on little bars of coral rubble. The center of the atoll is a shallow lagoon. The island bit of the atoll is a narrow ring of land around the lagoon, with coral reefs all around the outside of the island. Atolls generally rise up out of very deep water. An atoll may be a simple ring of island, or it may be a ring of several islands around a lagoon.
