Which ocean is the largest and deepest?

Which ocean is the largest and deepest?

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

Answer: (A)

This question is about which ocean holds the most area and the greatest depth. The Pacific Ocean is the largest in area, covering roughly 63 million square miles (about 165 million square kilometers). It also contains the deepest point on Earth—the Challenger Deep in the Mariana Trench—about 36,000 feet (around 11,000 meters) below the surface. This extreme depth arises from active plate tectonics around the Pacific Rim, where many subduction zones create deep trenches. The other oceans are smaller and have shallower maximum depths, so none reach both the vast size and the greatest depth of the Pacific.
