So how does it produce volcanic activity? …show more content…
Which then produce enormous volcanic eruptions and the molten rock that does not erupt become solid onto the edges of the plates as they spread apart.
Now let’s talk about the global distribution of the mid-ocean ridges and how they are spread around the whole globe. Mid-Atlantic Ridge and the East Pacific Rise are two most studied ridges by geologists. The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean and then spread slowly, forming a rift valley while the East Pacific Rise spread 5 times faster than the Mid-Atlantic ridge. Due its fast spreading, the East Pacific Rise doesn’t have a rift valley instead it possess a smooth volcanic summit with a crack throughout the crest.
