14. Most of the Philippine Islands were once part of island arcs. This means that
along with this boundary, there once existed two
A. converging continental plates C. converging oceanic plates
B. diverging plates
D. plates sliding past each other
15. Why are volcanoes mostly found at places where continents meet the seas?
A. It is where water meets land.
B. It is where the oceanic plates subduct under the continental plate.
C. Underneath it is a subduction zone.
D. More magma is produced under the ground because of the muddy seafloor.

Answer:
Plate Tectonics and Volcanism
Here are the answers:
13. D. converging, sliding past, and diverging
14. C. converging oceanic plates
15. B. It is where the oceanic plates subduct under the continental plate.
Explanation:
Earthquake causes the ground to shake, and it can happen when the plates collide, move away, or slide past each other.
When two continental plates converge, mountains form. When a continental and an oceanic plate converge, volcanic arcs form. When two oceanic plates converge, island arcs form.
Volcanoes form when the oceanic plate subducts underneath the continental plate. The friction that occurs during subduction would result to extreme temperatures, enough to melt the rocks from the subducting slab. These newly formed magmas are buoyant, so it would rise into the magma chambers above.
