WebA mid-ocean ridge is an underwater mountain system. This consists of mountain chains, with a rift valley running along its spine, formed by plate tectonics. A mid-ocean ridge marks the boundary between two tectonic plates which are moving apart. A mid ocean ridge is made by a divergent boundary. WebThe topographic form of the ridge was first revealed by precision depth records obtained during the pioneer polar crossings of the nuclear submarines Nautilus3 and Skate4.

WebIt was buoyant, making the subduction happen with a shallow angle. Eventually, the mid-ocean ridge itself was subducted, starting around 30 Ma.
