The mid - Atlantic ridge is a mid ocean ridge. The ridge lives along North South axis of the Atlantic oceans. The elevation of the ridge is about 2,350 meters and the highest point is Mount Pico.
The ridge is about 40 km crack in the ocean floor. It is formed by the movement of the continental plates (North American and Eurasian tectonic plates).
As the plates slowly separate, they leave gaps in the earth. This makes it possible for molten rocks that are beneath the earth to reach the earth surface which leads to the formation of a new part of the ocean floor and the formation of an underwater mountain system.
