D Both areas are on the boundary of active plate margins, the motion of the plates causes earthquakes.Both areas are on the boundary of active plate margins, the motion of the plates causes earthquakes.

Answer 1

The best explanation for why earthquakes are common in areas like California and Japan is:

D Both areas are on the boundary of active plate margins; the motion of the plates causes earthquakes.

This option accurately reflects the geological processes that lead to earthquakes, as both locations are situated along tectonic plate boundaries where the movement of these plates can produce seismic activity.
