What Happens at a Divergent Plate Boundary Divergent, convergent, and transform Plate Boundary Divergent Plate Boundaries: Where Continents Tear Apart Divergent plate boundary is the main cause of the continent to tear apart and started to form a mountain.  The driving force is the convection current from the mantle. The Birth of New Crust and Oceans The divergent boundary start to form a oceanic crust and ultimately a oceans because ocean water is on the oceanic crust. At divergent boundaries, tectonic plates move away from each other  The divergent boundary occur when the two plates move away from each other. Most divergent boundaries occur along mid-ocean ridges. New oceanic crust…
