What type of mountain range is the Mid-Atlantic Ridge?

The Mid-Atlantic Ridge is a divergent tectonic plate boundary and is classified as a mid-ocean ridge. It is located between the Eurasian Plate and the North American Plate in the North Atlantic Ocean, and between the African Plate and the South American Plate in the South Atlantic. This underwater mountain range is formed by the upwelling of magma, which creates new oceanic crust as the tectonic plates move apart. It is characterized by volcanic activity and hydrothermal vents.
