Highway to separate creating a gap. What type of plate boundary is found in this area?
A convergent boundary
C. subduction boundary
B. divergent boundary

3. The convergence of an oceanic plate and a continental plate gives rise to the formation
volcanic arc near the edge of the continental leading plate. Why is this so?
A. A trench is formed during the collision allowing magma from the mantle to ris
B. The collision of the two plates will force the magma out from the mantle causi
C. The collision will cause an earthquake that will force the magma to rise.
D. The subducted oceanic crust melts forming magma, becomes less dense allow
activities
