The deepest point of all the oceans is in the Pacific Ocean, in an area called Mariana Trench. At a place called "Challenger Deep," the ocean is 7 miles deep! This spot was discovered in 1951 by a British ship called Challenger II, and that's why the site is called "Challenger Deep." Of course, there may be a deeper place in the oceans that is still undiscovered - scientists are learning new things everyday, so who knows?
