What is waves of energy that travel through earth called?

Waves of energy that travel through the Earth are called seismic waves. They are generated by geological processes such as earthquakes or volcanic activity. Seismic waves are categorized into two main types: primary waves (P-waves), which are compressional waves that travel fastest, and secondary waves (S-waves), which are shear waves that travel slower. These waves provide important information about the Earth's internal structure and are key to understanding seismic events.
