The Mid-Atlantic Ridge, a submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is a divergent tectonic plate boundary. It is just one segment of the global mid-ocean ridge system that encircles the Earth. The rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year, or 25 km in a million years. The Mid-Atlantic Ridge separates the Eurasian Plate and the North American Plate in the North Atlantic, and separates the African Plate from the South American Plate in the South Atlantic.
