Reefs and Volcanoes: How Earth's Atolls Formed
Did you know that coral reefs and volcanoes have a very interesting connection? An atoll is a coral island surrounding a lagoon. Atolls are formed when a reef grows around a sinking volcanic island. This book explores the relationship between volcanoes and reefs and the "life" cycle of a volcanic island. Full-color photographs provide readers with connections to the text, and fact boxes and sidebars further explore topics related to the main text.
