6Mariana Trench, Pacific Ocean – The Deepest Point on Earth
The Mariana Trench is the deepest part of the world’s oceans, plunging to a depth of about 36,070 feet (10,994 meters) at its lowest point, known as Challenger Deep. Located in the western Pacific Ocean, this trench is a place of extreme pressure and perpetual darkness. The conditions at the bottom are so extreme that very few manned or unmanned submersibles have been able to reach it.
