What is the largest ocean?
The largest ocean on the planet Earth is the Quietocean. Its area is simply enormous. It is 166,241,700 square kilometers. It occupies most of the Earth's surface. It seems that the Earth is filled with water "to the eye". However, this is not quite true. Only a thin upper layer of the Earth contains water, the rest is a hard crust of stony rocks and a liquid inner core.
