Question

Quizplus · Accepted Answer

P waves (primary waves) and S waves (secondary waves) are both types of seismic waves that travel through Earth's interior. P waves are longitudinal waves that can travel through solids, liquids, and gases, while S waves are transverse waves that can only travel through solids. They both reflect and refract at boundaries between different materials in the Earth, leading to seismic activity and potentially causing damage on the surface.
