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 [[Atlantic Ocean|north Atlantic]] it separates the Eurasian and North American [[Tectonic Plate| plates]] and in the [[Atlantic Ocean|south Atlantic]] it separates the African and South American [[Tectonic Plate|plates]]. All of these [[Tectonic Plate|plates]] are still mocing moving apart and therefore the ridge grows by [[Approximate|approximatley]] 2.5cm every year.
