The ocean's deepest point is nearly seven miles down
Earth's deepest point, the Challenger Deep, plunges nearly seven miles into the Mariana Trench, harboring unique life despite immense pressure and remaining largely unexplored.
The Challenger Deep, Earth's deepest point, plunges about 6.8 miles into the western Pacific Ocean's Mariana Trench. This immense depth, first charted in 1951, creates crushing pressure over 1,000 times that at sea level. Despite these extreme conditions, scientists have found thriving ecosystems of unique deep-sea creatures.
