The Pacific Ocean is the largest ocean in the world. It is so large that all of the land on Earth could fit inside of it. In addition, it contains more than fifty percent of the world's water - more water than all of the lakes, rivers, and other oceans combined. Finally, this vast ocean also contains the world deepest point, the Marianas Trench (35,979 feet).
The Pacific Ocean was named by explorer Ferdinand Magellan who called it "mar pacifico" or, the peaceful sea. As he sailed through terrible sea storms on his way to Asia, he realized he gave the huge ocean the wrong name!
