Question

what type of plate collision results on the formation of an arc of volcanic islands such as mariana islands in the North Pacific Ocean?

Answer 1

Convergent , specifically subduction

Step-by-step explanation:

Volcanic arcs are usually a result of two plates colliding. The areas where they meet are called convergent zones. This happens when two tectonic plates move towards each other. In the case of volcanic arcs, one plate is pushed down by the other because of the difference of densities. Oceanic plates are denser than continental plates and when they collide, the oceanic plate is pushed down, this is called subduction.
