“The ridge system forms the longest and largest mountain range on Earth, winding its way between the continents,” NOAA continues.
The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).”
“The mid-ocean ridge is the most extensive chain of mountains on Earth, with more than 90 percent of the mountain range lying in the deep ocean.

“Despite being such prominent feature on our planet, much of the mid-ocean ridge system remains a mystery. While we have mapped about half of the global mid-ocean ridge in high resolution, less than one percent of the mid-ocean ridge has been explored in detail using submersibles or remotely operated vehicles.”
