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.
Volcanoes form at divergent plate boundaries, and at convergent plate boundaries between oceanic and continental plates or between two oceanic plates (subduction zones). All types of plate movements cause earthquakes, including transverse movements where two plates slide along each other, and convergent boundaries between two continental plates (these two types generally do not result in volcanism). Divergent boundaries, or rifts, are places where two plates move apart from each other.
