How are mid-ocean ridges formed at divergent tectonic plates? a. the plates are moving in a zigzag formation, creating shallow earthquakes which forms a mid-ocean ridge. b. mid-ocean ridges are not resulting features of ocean-to-ocean divergent boundary zones. c. the plates are moving towards each other, which causes the crust to buckle and push upwards or sideways which forms a mid-ocean ridge. d. the stretching lithosphere is pushed up as the plates move apart.
