Full Answer

Aluminum reacts with water to form aluminum oxide. This oxide forms a protective barrier over the object to prevent damage from water.

Pollution from industrial processing also increases the amount of aluminum in the oceans. The Atlantic Ocean has a higher aluminum concentration than the Pacific.
