 | Creation and extinction of an oceanic island. First, a volcano emerges from water, forming an island. Second, the island makes a platform which increases the diameter of the island. Third, the shore rocks crumble to form soil. Last, the island disappears leaving a barrier reef of coral, or atoll. Figure source: http://www.panda.org/kids/wildlife/mnisland.htm |
