In Geology. A convergent boundary with no subduction is a continental-continental boundary. Because oceanic crust is denser than continental crust, it is always the subducting plate in a â¦ oceanic-continental boundary.In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors.ecause oceanic crust is denser than continental crust, it is always the subducting plate in a â¦ oceanic-continental boundary. In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors.
Convergent boundaries form when two crustal plates are colliding. The plates form a subduction zone with one plate descending beneath the other plate.One of the converging plates must be an oceanic plate to form a subduction zone. When two continental plates collide mountain ranges like the Himalayas form.Trenches form at subduction zones, USGS. Subduction zone. The subducting plate is being recycled as it begins to melt at about 100 kilometers.onvergent Boundaries. Introduction. Convergent boundaries form when two crustal plates are colliding. The plates form a subduction zone with one plate descending beneath the other plate. One of the converging plates must be an oceanic plate to form a subduction zone.
