Plate tectonics two oceanic plates, an oceanic and continental plate, or between provides the mechanism to recycle the Earthâs crust. Destruction (recycling) of crust takes place along convergent Divergent Margins boundaries where plates are moving toward each other, and sometimes one plate sinks (is subducted) beneath another.
