Seismic Waves

• What are the names of the two types of seismic waves?

  -P-Waves and S-Waves
• What are the differences between P-Waves and S-Waves?

  -P-Waves are Longitudinal

  -S-Waves are transverse

  -S-Waves cannot travel through liquids whereas P-Waves can travel through liquids
• What does a P-Wave graph look like?

  It showcases that P-Waves can travel through the earths core as they can pass through solids and liquids (Earths core liquid)

  
• What does an S-Wave graph look like?

  -They cannot pass through liquids and therefore cannot pass through the earths core

  
• What type of wave can travel through the Earths core?

  -P-Waves
• What type of wave is faster?

  -P-Waves are faster than S-Waves. S-Waves speed increases as density increases but P-Waves are faster
• How are seismic waves used to identify the Earths shell contents?

  -P-Waves can pass through liquids and S-Waves cannot therefore we can identify that the earths core is liquid as S-Waves cannot travel through it. This also tells us that the outside of the earths core is solid
