The Mid-Atlantic Ridge is an oceanic ridge or volcanic mountain range submerged in the Atlantic Ocean and extending from north to south (from a few kilometers south of the North Pole to the Bouvet Island, a few kilometers north of the Antarctica).
This ridge is divided into the equator by the deep Romanche pit and separates four tectonic plates:
-In the North Atlantic: separates the Eurasian and North American plates.
-In the South Atlantic: separates the African and South American plates.
