A. A P wave moves particles up and down or side to side.
B. A P wave can move through solid rock only.
C. A P wave can travel through liquids.
D. A P wave travels more slowly than an S wave.
P waves can travel through any type of a material whether solid, liquid or gases because of their wave movement. On the other hand S-waves can only travel through solids.
S waves are slower than P waves and can only move through solid rock and not through any liquid or gaseous medium. Therefore s-waves are shear waves.
