(Spanish for "table")

An island is any piece of land smaller than a continent and larger than a rock, that is completely surrounded by water. Very small islands are called islets. Although seldom adhered to, it is also proper to call an emergent land feature on an atoll an islet, since an atoll is a type of island. A key or cay is also another name for a relatively small island. Groups of related islands are called archipelagos. There are three main types of islands: continental islands, river islands, and volcanic islands. There are also some artificial islands.

Island
