Answer 1

The two correct answers for the processes important in the formation of volcanic arcs at the edge of continental plates are:

• subduction
• uplift

Subduction occurs when one tectonic plate moves under another and sinks into the mantle, leading to volcanic activity. Uplift is also involved as the subducting plate can cause the overlying plate to rise, contributing to the formation of volcanic arcs.
