How Deep Is It?

The answer to that question depends on where you are. If you are walking along either coast of the United States, the ocean reaches right up to the coastline. You can put your feet into it. But there are sections of the ocean that are almost 7 miles deep!

The Mariana Trench located in the Pacific Ocean is 6.7 miles deep. The Puerto Rico Trench in the Atlantic Ocean is over 5.5 miles deep. Animals live in all areas of the ocean even at its deepest points, many of which have never been seen by human eyes.
