Which ocean contains the largest underwater mountain chain?

Atlantic Ocean
The longest submarine mountain range is the Mid-Ocean Ridge, extending 65,000 km (40,000 miles) from the Arctic Ocean to the Atlantic Ocean, around Africa, Asia and Australia, and under the Pacific Ocean to the west coast of North America. It has a greatest height of 4,200 m (13,800 ft) above the base ocean depth.

Which is the deepest and biggest ocean on Earth?

The Pacific Ocean
The Pacific Ocean is the largest and deepest of the world ocean basins.

All of the world’s continents could fit into the Pacific basin.
