Is Challenger Deep really the deepest point on Earth?
The Challenger Deep is the lowest point in the Mariana Trench, a gap between tectonic plates that stretches 1,500 miles along the western Pacific, and is thought to be the deepest chasm in all the world’s oceans. At the bottom the pressure reaches over 15,000 pounds per square inch.
