Where is the deepest known point in the ocean?

The Mariana Trench formed through subduction, where one tectonic plate is forced beneath another, creating a deep, curving trench along the boundary in the western Pacific. At its deepest point, the Challenger Deep, the seafloor plunges nearly 11 kilometers — so extreme that if Mount Everest were placed at the bottom, its peak would still sit more than two kilometers beneath the surface.

The Bermuda Triangle is a loosely defined region associated with folklore rather than any verified depth record, and the Red Sea, though a significant rift valley, is nowhere near as deep.

Because pressure at that depth is roughly a thousand times greater than at sea level, only a handful of specially engineered vehicles have ever successfully reached the Challenger Deep's floor.
