What is the deepest ocean?

The Pacific Ocean is recognized as the deepest ocean in the world, primarily due to the presence of the Mariana Trench, which reaches depths of about 36,000 feet (over 10,900 meters). This trench is the lowest point on the Earth's surface and exemplifies the extreme topography found in the Pacific. The ocean encompasses a vast area, covering more than one-third of the Earth's surface, and its significant depth contributes to a variety of marine ecosystems and geological features.

In comparison, the Atlantic Ocean, Indian Ocean, and Arctic Ocean, while they all have significant depths, do not reach the extreme levels found in the Pacific. Therefore, its distinction as the deepest ocean is well established in oceanographic studies and measurements.
