Mid-Ocean ridges are what?
What is a long seismically, active ridge system situated in the middle of a large ocean basin; it marks the site of upwelling magma and is associated with seafloor spreading.

At a transform fault what do the plates do and when this happens what does this cause?
What is the plates slide past each other and build up tension to the point where the plates bounce back and cause an earthquake.
