The mid-ocean ridge system is the longest continuous divergent plate boundary on Earth.

These ridges are spreading centers or divergent plate boundaries

The 3 types of plate boundaries that occur is the spreading boundary, fracture boundary, and the colliding boundary.
Sea floor spreading is caused by convection currents in the mantle to cause a divergent boundary underwater. When the divergent boundary spreads, it caues a mid-ocean ridge. This is sea-floor spreading. Hope I helped!
