File:Atoll forming-Atoll.png
Summary
Internationalization of the diagram:Atoll forming.
1=Volcanic Island
2=Fringing reef
3=Barrier reeef
Caption: Coral atolls develop from reefs fringing volcanic islands. As first hypothesized by Charles Darwin, and confirmed by ocean drilling done by British scientists a century ago, reefs fringing volcanic islands build vertically to sea level, forming steepwalled barrier reefs. As a volcanic island subsides, or sinks, with time, the growing reef keeps pace with the rising water level. When the island eventually submerges, the ring-shaped reef forms an atoll with a central lagoon.
