Subduction zones are broad areas where two. plates are moving in opposite directions. The. oceanic plate descends beneath a continental. plate in this example. [See Divergent and. Convergent Plate Boundaries for more-. detailed depictions].
Plates include both oceanic crust and continental crust. Stable subduction zones involve the oceanic lithosphere of one plate sliding beneath the continental or oceanic lithosphere of another plate due to the higher density of the oceanic lithosphere. That is, the subducted lithosphere is always oceanic while the over-riding lithosphere may or may not be oceanic.
