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.

"Continental drift" hypothesis that states that the continents were once one large mass that broke apart.
The continental drift hypothesis was created in the early piece of the twentieth century, for the most part by Alfred Wegener. Wegener said that mainlands move around on Earth's surface and that they were once consolidated as a solitary supercontinent. While Wegener was alive, researchers did not trust that the mainlands could move.
