Question

Quizplus · Accepted Answer

Atolls are ring-shaped islands of coral reefs. The center of these reefs has a lagoon. The coral is not successful within the lagoon so there can be an accumulation of coral debris. Some of these islands are able to sustain palm trees in the center-the true image of a tropical island. Information can be found in the section Biological Activity Forms and Modifies Coasts.
