Mariana Trench
The deepest place on Earth/Water
The Mariana Trench plunges nearly 11 kilometers below the Pacific Ocean's surface. At its deepest point, Challenger Deep, the water pressure is over a thousand times atmospheric pressure -- enough to crush most submarines. Despite the crushing darkness and cold, life persists down there, including shrimp-like amphipods and xenophyophores.
