Explanation:
Detailed explanation-1: -Volcanism occurs at convergent boundaries (subduction zones) and at divergent boundaries (mid-ocean ridges, continental rifts), but not commonly at transform boundaries.
Detailed explanation-2: -destructive boundaries (convergent): where plates are moving towards each other and old crust is either dragged down into the mantle at a subduction zone or pushed upwards to form mountain ranges. transform boundaries (conservative): where are plates are moving past each other and crust is neither created nor destroyed.
