The transverse (or S-waves) travel through Earth's crust more rapidly than do the compressional (or P-waves).

Question

Quizplus · Accepted Answer

P-waves, or primary waves, travel faster than S-waves, or secondary waves, through the Earth's crust. P-waves are compressional waves that can move through both solid and liquid layers of the Earth, whereas S-waves are shear waves that can only move through solid materials, which contributes to the difference in their speeds.
