passing over a hotspot

Answer 1

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

1. Subduction - This process occurs when one tectonic plate is forced under another, leading to melting of the subducted plate and the formation of magma, which can create volcanic arcs.

2. Uplift - While uplift itself is not a direct cause of volcanic arc formation, it is often a result of subduction and the associated volcanic activity, contributing to the formation of the arc itself.

Thus, the primary correct answer is subduction; however, uplift can be related to the processes involved in the formation of volcanic arcs. Passing over a hotspot does not specifically relate to arc formation at continental plate edges and plate divergence is typically associated with mid-ocean ridges rather than arcs at continental boundaries.
