Geography The Mariana Trench
The Mariana Trench's Challenger Deep reaches 36,070 feet below sea level - deeper than Mount Everest is tall. At this depth, pressure exceeds 1,000 atmospheres, enough to crush most submarines. Despite extreme conditions, life thrives including amphipods, fish, and bacterial mats. More people have been to the moon than have visited the deepest part of the ocean, making it Earth's least explored frontier.
