How do subduction zones form

A subduction zone forms when continental crust and oceanic crust collide. The continental crust is thicker and more buoyant than the oceanic crust so the oceanic crust subducts beneath the continental crust. ... Volcanoes associated with subduction zones generally have steep sides and erupt explosively.
