How would the angle of subduction of a tectonic plate influence the location of a volcanic arc?
A)The steeper the angle, the closer the arc would form to the trench
B)The shallower the angle, the closer the arc would form to the trench
C)The steeper the angle, the further the arc would form to the trench
D)The angle of subduction doesn't affect the location of the volcanic arc

Question

Quizplus · Accepted Answer

The steeper the angle of subduction, the more intense the melting that occurs at the subduction zone. This results in the formation of magma, which then rises to the surface and forms a volcanic arc. Therefore, the closer the arc would form to the trench if the angle of subduction is steeper.
