A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of ~ 2,600 meters (8,500 ft) and rises about two kilometers above the deepest portion of an ...

By comparison, the temperature of crustal fluids can reach 400 degrees C at hydrothermal vents in the Mid-Atlantic Ridge, where tectonic plates are diverging and new oceanic crust is being formed.

The world's mid-ocean ridges form a single, connected global ridge system that is part of every ocean, and is the longest mountain range in the world. Geologically active, mid-ocean ridges are key ...

The researchers examined the differences in gravity at 122 data sites on mid-ocean ridges around the globe, as well as the rate at which the ridges were spreading apart, to infer magma supply ...
