Final answer:
P-waves and S-waves have different properties and speeds, with P-waves being faster and able to travel through solids, liquids, and gases, while S-waves can only travel through solids.
Explanation:
P-waves are primary waves that move back and forth, compressing material, while S-waves are secondary waves that move material side to side, perpendicular to their travel direction. P-waves are faster than S-waves, traveling at a speed of 6 to 7 km/s compared to S-waves' speed of 2 to 5 km/s. P-waves can travel through solids, liquids, and gases, while S-waves can only move through solids due to their shear motion.
