Which ocean is the deepest, reaching about 10,984 meters at the Challenger Deep?

The Pacific Ocean is the deepest ocean, reaching about 10,984 meters at the Challenger Deep.

The Challenger Deep lies in the Mariana Trench, east of the Mariana Islands in the western Pacific. Measurements vary slightly with surveying methods, but the site is generally described as nearly 11 kilometers below sea level, making it the deepest known point in Earth’s oceans.

The Pacific is also the largest ocean, covering about one-third of Earth’s surface. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia on the west and the Americas on the east.

Its floor contains extensive subduction zones, where oceanic plates sink beneath neighboring plates. This tectonic activity helps form the Pacific Ring of Fire, a zone known for frequent earthquakes, volcanic eruptions, and deep ocean trenches.
