Which ocean is the deepest?

Which ocean is the deepest?

• A. Pacific Ocean
• B. Atlantic Ocean
• C. Indian Ocean
• D. Arctic Ocean

Answer: (A)

Ocean depth varies because of how tectonic plates move and form features like deep trenches. The deepest places on Earth lie in trenches where one plate slides beneath another, and the Pacific Ocean has the most extensive trench system. Its deepest point, the Challenger Deep in the Mariana Trench, is about 11 kilometers (roughly 36,000 feet) below the surface. That combination of widespread, very deep trenches makes the Pacific the deepest ocean. The other oceans have deep spots too, but not as deep, with the Arctic Ocean being the shallower among them.
