The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources. Scientists use a variety of technologies to overcome the challenges of deep-sea exploration and explore the Trench.
The bottom of Challenger Deep is about 36,000 feet below sea level. That's nearly seven miles! This makes it the deepest known place on Earth.
While atmospheric pressure in the average home or office is 14.7 pounds per square inch (PSI), it is more than 16,000 PSI at the bottom of the Mariana Trench
