Answer:
C. P waves move matter back and forth, in a direction parallel to the direction of the wave, while S waves move matter up and down, perpendicular to the direction of the wave.
Explanation:
P and S - waves are both called seismic waves. They are produced during deformation within the earth.
Usually, P or Primary waves have the fastest velocity and arrives at the seismic station first. Secondary, Shear or S-waves follows P-waves.
- P-waves are body waves that propagates within a body. They cause movement internally.
- Secondary waves are surface waves. They move on the surface of earth.
- One way to also distinguish between these two seismic waves is that, P-waves are longitudinal waves that travels parallel or longitudinally to the source.
- Secondary waves moves in an up and down motion pattern. They propagate transversely to their source.

The continental plate is less dense that the oceanic plate and so sinks underneath the oceanic plate. The oceanic plate holds water and so when the continental plate sinks underneath it, the water from the oceanic plate covers the continental plate.
