Question

Question is about earthquakes.

P waves ________.

A) propagate only in solids

B) are faster than S waves and surface waves

C) have higher amplitudes than do S waves

D) produce the strongest ground shaking

Answer 1

Choice (b) is correct. P waves move faster than S waves and surface waves. In addition, these are the waves that travel through water: S waves are able to only travel through solid forms. P waves are much less damaging, by comparison, than S waves and can be used as a notification for when the more damaging aspects of an earthquake are about to take place.
