What type of effect is found in P waves?
Answer and explanation
Correct answer: Compression and rarefaction
P-waves are longitudinal, or compressional, seismic waves. Particles in the material vibrate back and forth parallel to the direction of wave travel, creating alternating regions of compression and rarefaction. This particle motion allows P-waves to travel through solids, liquids and gases. Transverse displacement is characteristic of S-waves, while rotational motion and surface-wave motion do not describe the defining effect of P-waves.
