If You Detonated a Nuclear Device In The Marianas Trench

The Mariana Trench or Marianas Trench, is the deepest part of the world’s oceans. It reaches a maximum known depth of 10,994 meters (36,070 ft.). For comparison, if Mount Everest were dropped into the trench, its peak would still be over 1.6 kilometers (1 mi) underwater. What would happen if a nuclear device was detonated there?
