Answer 1

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

1. Subduction - This is the process where one tectonic plate moves under another and sinks into the mantle, leading to melting of the subducted plate and resulting in volcanic activity.

2. Uplift - This process can occur as a result of volcanic activity and the accumulation of volcanic material, contributing to the formation of elevation in volcanic arcs.

So the correct answers are subduction and uplift.
