Study Notes
Seismic Waves
- Seismic waves are vibrations that travel through the Earth.
- Seismic waves are generated by earthquakes and recorded by instruments called seismographs.
Types of Seismic Waves
- There are three main types of seismic waves: primary waves (P-waves), secondary waves (S-waves), and surface waves (Love waves and Rayleigh waves).
- P-waves are the fastest and can travel through both solids and liquids.
- S-waves are slower and can only travel through solids.
- Love waves are the fastest surface waves and cause side-to-side motion.
- Rayleigh waves cause an elliptical motion like ocean waves.
How Seismic Waves Provide Information About the Earth's Interior
- Changes in the speed of seismic waves as they travel through the Earth provide information about the Earth's interior.
- P-waves are refracted (bent) and reflected (bounced back) when they encounter changes in density and composition.
- The sudden change in velocity and direction of seismic waves at specific depths indicate boundaries between different layers of the Earth.
