The deepest part of the ocean is known as the Challenger Deep, which is located in the Mariana Trench in the western Pacific Ocean. This astonishingly deep area reaches a depth of about 36,000 feet, or nearly 11,000 meters.
The Challenger Deep is not only the deepest known point in the ocean, but it also presents some of the most extreme conditions on Earth. The pressure there is over 1,000 times the standard atmospheric pressure at sea level, making it incredibly challenging for any form of life to exist.
Exploration of this mysterious part of the ocean has been limited due to its extreme depth and accessibility. However, several manned and unmanned expeditions have ventured into the Challenger Deep, helping researchers gather valuable data about the unique ecosystems and geological features that exist in such a harsh environment.
