The image shows the Pacific Ring of Fire, a region of high tectonic activity. What evidence supports the theory that the tectonic activity of the region is due to the subduction of tectonic plates?

• The region is bound by many oceanic trenches.
• North America seems to be colliding with Asia at the north of the ring.
• The Asia-Pacific region is dotted by many small and large islands
• The landmasses look like they would fit together like the pieces of a jigsaw puzzle.

In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

• The strong ocean currents are undermining both areas causing earthquakes.

• Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.

• Both areas are subjected to strong ocean wind and waves that causes earthquakes.

• Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.
