The Atlantic Ocean is the second largest body of water in the world and covers one-fifth of the Earth's surface!
The Atlantic Ocean has an area of approximately 82 million square kilometres not including its surrounding seas and bays. When the Mediterranean, Black, Baltic, North, Norwegian-Greenland, and Caribbean Seas, Baffin and Hudson Bays and the Gulf of Mexico are also considered, its area rises to about 106 million square kilometres. It is the world’s second largest ocean, and covers approximately one-fifth of the Earth’s surface. This vast expanse of water holds approximately 350 million cubic kilometres of water, and receives about four times more inflow from the rivers of surrounding land regions than either the Pacific or Indian Oceans.
