Question

Quizplus · Accepted Answer

P-waves are a type of seismic wave that travels through the Earth's interior and are characterized by a back-and-forth motion that is parallel to the direction of wave motion. This is known as longitudinal motion, which means that the particles in the material through which the P-wave passes vibrate back and forth along the same direction as the wave. Therefore, the correct choice is C (longitudinal).
