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.
A convergent boundary (or destructive boundary) is where two plates are moving towards each other -- where they're colliding. The pressure and friction is great enough at these boundaries that the material in the Earth's mantle can melt, and both earthquakes and volcanoes happen nearby.xamples of Convergent Boundaries. The west coast of South America is a convergent boundary between the Nazca plate and the South American plate. The collision of this oceanic and continental plate was how the Andes mountains were formed.
