If you were to ask someone what the tallest mountain in the world was, or what the largest geological structure on the earth was; they would probably say Mt. Everest. Of course if you’re measuring how far said structure reaches into the sky, you would be correct. But often people forget what lies just beneath our oceans.
The world’s tallest geological structure is actually Mauna Kea in Hawaii. Mauna Kea only extends 13,796 feet above sea level, but what’s below the sea reveals a monster of a mountain. In total, Mauna Kea is 33,500 feet tall; over 10,000 feet taller than Everest.
The Mid-Ocean Ridge is a vast interconnected underwater mountain system that reaches into every ocean. The mountain range is 40,400 miles (65,000 km) long, making it the largest geological structure in the world.
The Ocean is one of the last places on Earth we have yet to fully explore. There are mountains and valleys below its surface that dwarf those we know above it. Be it geologically or biologically, the Ocean holds things we can scarcely imagine.
