Geography Worksheets – Oceans of the World


The large and deep bodies of water that remain in the great spaces between the continents are called oceans. The oceans are the vast, open seas that separate the continents,  and they are much wider and deeper than the seas.

Oceans with an average depth of 3 thousand meters cover two-thirds of our world, that is, approximately 70% of the earth.

The word ocean comes from the Greek “Okeanos” meaning “river”, the Greeks noticed the strong current coming from the Strait of Gibraltar and thought it was a river.

There are five oceans in the world: the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean. Among them, the world’s largest ocean is the Pacific Ocean. 

1. Pacific Ocean

The Pacific Ocean is the world’s largest ocean and is located between the continents of America, Asia, and Oceania. The explorer, who gave his name to this ocean, saw the calmness of this ocean during his voyage of discovery and named it pacifico, which means calm. Mariana Trench, which is the deepest place and also the deepest point in the world, is 11,034 meters deep.
