What is the best description of the paths of S waves and P waves? S waves travel through Earth's interior. P waves travel along the surface of Earth's crust.

S waves travel through solids or very dense, glassy liquids. P waves travel through solids, liquids, and gasses.

Explanation:

S-waves and P-waves are both body waves that moves through a substance. They are different from surface waves that moves on the surface. These surface waves are love and Rayleigh waves.

 The body P-waves and S-waves are often differentiated by the materials they propagate through. P-waves are primary waves and they pass through any earth materials. They can be propagated through solids, liquids and gases. This is because they are longitudinal waves.

S-waves are shear waves and they cannot pass through liquids and gases. These materials do no shear.
