Which processes are important in the formation of volcanic arcs at the edge of the continental plate select the two correct answers subduction passing over a hotspot plate divergent or uplift

Answer 1

The two correct processes important in the formation of volcanic arcs at the edge of a continental plate are:

1. Subduction - This is a key process where one tectonic plate moves under another and sinks into the mantle. Subduction of an oceanic plate beneath a continental plate leads to the formation of volcanic arcs.

2. Uplift - While uplift itself is not directly responsible for the formation of volcanic arcs, it is often associated with the tectonic activity resulting from subduction. The resulting pressure and melting of the mantle can contribute to volcanic activity, leading to the formation of volcanic arcs.

The other options, "passing over a hotspot" and "divergent plate boundaries," are related to volcanic activity but do not specifically relate to the formation of volcanic arcs at the edge of a continental plate like subduction does.
