An ocean is a body of saline water that composes a large part of a planet’s hydrosphere. (The word “sea” is often used interchangeably with “ocean” but, strictly speaking, a sea is a body of saline water (possibly a division of an ocean) partly or fully enclosed by land.)
Our Earth has five oceans. In descending order from largest to smallest, they are the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans.
The Pacific Ocean is the largest of Earth’s oceans. At 63.8 million square miles, it covers about 46% of the Earth’s water surface and about one-third of its total surface area, making it larger than all of Earth’s land area combined.
Subdivided by the equator into the North Pacific and South Pacific, the Pacific Ocean extends from the Arctic in the north to the Southern (or Antarctica) Ocean in the south, bounded by Asia and Australia in the west, and the Americas in the east. The Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 35,797 ft or 6.78 miles.
Below is a breathtaking underwater video, shot in high definition, whilst scuba diving in the waters of Fiji islands and Tonga in the South Pacific. You’ll see colorful coral reefs, huge schools of tropical fish, sharks, humpback whales, underwater caves, scuba divers and much more.
I recommend you watch in Full Screen mode!
