A mid-ocean ridge (MOR) is an underwater mountain system formed by plate tectonics. The depth of the seafloor (or the height of a location on a mid-ocean ridge above a baselevel) is closely correlated with its age (age of the lithosphere . A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary. The nearly continuous, global Mid-Ocean Ridge system snakes across the Earth's surface like the seam on a baseball. It is clearly visible on this map of global.

The mid-ocean ridge occurs along boundaries where plates are spreading apart. anything found on dry land, and includes a collection of volcanic ridges, rifts. Mid-ocean Ridges can be found in all of the oceans. Schematic map showing the locations and names of the world's mid-ocean ridges.

Worldwide distribution of mid-oceanic ridges, as mapped by the U.S. . Mid- ocean ridges. Present. Chile ·East Pacific ·Explorer ·Gakkel ·Gorda. In the past these features were referred to as mid-ocean ridges, but, as will be seen, Oceanic ridges are found in every ocean basin and appear to girdle Earth. A mid-ocean ridge is formed in the same place where seafloor spreading ocurrs. Tectonic plates spread and magma is pushed up, creating a ridge. Location of Mid-Ocean Ridges. It turns out, global mid-ocean ridges are largest mountain chain on Earth. They wind through more then 40,
