Which ocean is the largest and deepest?

Which ocean is the largest and deepest?

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

Answer: (D)

Understanding how we compare oceans by size and deepest points helps you see why the answer is the Pacific Ocean. It is the largest by area, spanning roughly 165 million square kilometers, and it also contains the deepest location on Earth—the Challenger Deep in the Mariana Trench, at about 10,970 meters. The Atlantic and Indian Oceans are smaller in both area and average depth, and the Arctic Ocean is the smallest and shallowest of the four. So the Pacific stands out as the biggest and deepest.
