What type of plate boundary leads to subduction? Convergent plate boundaries lead to subduction. Subduction occurs  when one tectonic plate rides over the edge of another tectonic  plate which sinks into the mantle as theyâ¦ converge.
Divergent boundaries are constructive boundaries because new crust is generated by magma pushing up from the mantle as the plates pull away from each other. Seafloor Spreading. Divergent boundaries in the middle of the oceans cause seafloor spreading. As the oceanic plates move apart they produce cracks in the ocean floor.
