WebDivergent Plate Boundaries. Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the ... Web- In ocean-ocean plate convergence, as the two plates move towards each other, the older, colder denser oceanic plate sinks into the mantle. - In ocean-continental plate convergence, the oceanic basaltic plate is denser than the granite-type continental crust, thus, as the crusts move towards each other the oceanic crust subducts under the continental crust.
