![](dot.gif) ![](thumb-oceanislnd.jpg) | 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.
