Answer:
The processes that are important in the formation of volcanic arcs at the edge of continental plates are: subduction of the oceanic plate, mantle wedge convection, and slab break-off.
Step-by-step explanation:
Subduction of the oceanic plate is the process that is most important in the formation of volcanic arcs at the edge of continental plates.
The processes that are important in the formation of volcanic arcs at the edge of continental plates are subduction and volcanism. Subduction is the process by which one plate is pushed underneath another plate. This process can happen at either a convergent or a divergent boundary. The plate that is being subducted is called the subducting plate, and the plate that is on top is called the overriding plate. The subduction process can create a lot of friction, which can lead to volcanism.
