Final answer:
Seismic waves can be categorized into different types based on how they travel through the body of the Earth. The two main types of seismic waves are P-waves and S-waves.
Step-by-step explanation:
Seismic waves can be categorized into different types based on how they travel through the body of the Earth. The two main types of seismic waves are <strong>P-waves</strong> (pressure waves) and <strong>S-waves</strong> (shear waves).
P-waves are longitudinal waves that travel through solids, liquids, and gases. They compress and expand the material they pass through.
S-waves are transverse waves that only travel through solids. They shake the material perpendicular to the direction of the wave travel.
These seismic waves provide valuable information about the composition and structure of the Earth's interior.
