Seismic waves

• Seismic wave

  Waves that travel through the Earth

  They cause earthquakes, volcanic eruptions, and large explosions
• What device is used to detect seismic waves

  Seismometer
• Why do scientists study seismic waves

  Helps us understand the internal structure of the earth

  It allows us to detect earthquakes early
• What type of scientist studies seismic waves?

  Seismologist
• Two types of seismic waves

  P-waves

  S-waves
• What physical states can P-waves travel through

  All of them
• Are P-waves transverse of longitudinal

  Longitudinal
• What physical states can S-waves travel through

  Can only travel through solids
• Are S-waves transverse or longitudinal


  Transverse
• Do P-waves or S-waves travel faster


  P-waves
• What physical state is the mantle

  Solid
• What physical state is the outer core

  Liquid
