About the Mid-Atlantic ridge

The mid-Atlantic ridge is a Constructive Plate Margin that largely runs along the floor of the Atlantic Ocean with some areas that elevate above the water. In the north Atlantic it separates the Eurasian and North American plates and in the south Atlantic it separates the African and South American plates. All of these plates are still moving apart and therefore the ridge grows by approximately 2.5cm every year.
