The mid-ocean ridge system is the most extensive chain of mountains on Earth, stretching nearly 65,000 kilometers (40,390 miles) and with more than 90 percent of the mountain range lying underwater, in the deep ocean.

A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary.
10 lis 2020 · The mid-ocean ridge is a continuous range of undersea volcanic mountains that encircles the globe almost entirely underwater. It is a central feature of seafloor terrain that is more varied and more spectacular than almost anything found on dry land, and includes a collection of volcanic ridges, rifts, fault zones, and other geologic features.
The mid-ocean ridges are the Earth’s largest volcanic system, accounting for more than 75% of all volcanic activity on the planet. The heat from this volcanism is dispersed by hydrothermal circulation of seawater.
Oceanic ridge, any of several submarine mountain chains rising from the ocean floor. Individually, the ridges are the largest features in ocean basins. Collectively, they form the worldwide oceanic ridge system—at about 80,000 km (50,000 miles) long, Earth’s largest surface feature after continents and ocean basins.
1 sty 2023 · Mid-ocean ridges are divergent plate boundaries where new oceanic crust and lithosphere form through a complex interplay of magmatic, hydrothermal, and tectonic processes. Magma is generated tens of km below the ridge by adiabatic decompression of upwelling asthenosphere.
The mid-ocean ridge system is the most extensive chain of mountains on earth, but more than 90% of this mountain range lies in the deep ocean. The mid-ocean ridge wraps around the globe for more than 65,000 km like the seam of a baseball.
