How Deep Is the Ocean? | If You've Ever Wondered
If Mount Everest stood at the deepest point in the ocean, its summit wouldn't even break the surface. So how deep does the ocean actually go? In this animated journey, we take an imaginary elevator from beneath a cruise ship all the way down until we run out of ocean. We pass through the sunlight, twilight and midnight zones, meet glowing deep-sea animals, measure ourselves against the ocean's average depth and the wreck of Titanic, and descend into the hadal zone of the Mariana Trench. At the very bottom is Challenger Deep, nearly 11 kilometres down. Then we bring Everest back to see just how much ocean would still be above its summit.
