The reality side is highlighted, Text, Although some portions are flat, the ocean floor also contains long mountain chains, isolated hills and mountains, and deep trenches. The Mid-Atlantic Ridge rises about a mile above the ocean floor, while the Mariana Trench plunges to 36,000 feet (11,000 meters) at its deepest—farther below sea level than Mount Everest ascends above sea level.
