Which Ocean Is Deeper: The Atlantic or the Pacific?
The Pacific Ocean is deeper than the Atlantic Ocean, both in terms of average depth and deepest point. The Pacific Ocean has a mean depth of approximately 14,040 feet (4,280 meters), and it boasts the deepest known point in the world’s oceans, the Challenger Deep, located in the Mariana Trench, which plunges to a staggering 36,070 feet (10,994 meters) below sea level.
In comparison, the Atlantic Ocean, while still impressively profound, does not reach the same depths as the Pacific. The Atlantic’s average depth is about 11,962 feet (3,646 meters). Its deepest point is the Milwaukee Depth, in the Puerto Rico Trench, which lies 27,493 feet (8,380 meters) below sea level.
