D. S waves travel along the surface of Earth's crust. P waves travel through Earth's interior.

Respuesta :

D. S waves travel along the surface of Earth's crust. P waves travel through the Earth's interior. 

This is why P waves arrive at the detector first, in addition to the fact that they can travel through solids, liquids, AND gases.
D. p waves happen first, because it’s primary.
