Anatomy of Mid-Ocean Ridges

    A mid ocean ridge is a long, seismically active submarine ridge system situated in the middle of an ocean basin and marking the site of the upwelling of magma associated with seafloor spreading. One of the most studied mid ocean ridge is Mid-Atlantic Ridge, which is part of the longest mountain range in the world. 

    As you can see in the pictures, the Mid-Atlantic Ridge is formed along a combination of transform and divergent boundaries, according to the key. As the definition stated earlier said, mid ocean ridges allow the upwelling of magma, and contribute to seafloor spreading, so it would make sense that divergent and transform boundaries would be associated with this feature. The screenshots show an actual mountain range. For some reason, it's crazy to me to think that there are mountains under the ocean, but 90% of the range the Mid-Atlantic Range is a part of, it underwater.
