  1. 1What do Earthquakes Cause?
    1. AShock waves, they travel on the surface and inside earth. We record them with Seismographs.
    2. BOcean Trenches.
  2. 2What Two Types of Waves are there.
    1. AP-Waves and S-Waves
    2. BD-waves and M-waves
  3. 3Explain P-Waves
    1. AThey go through Solids and Liquids.
      They are faster than S-Waves.
      They are Longitudinal.
    2. BThey only travel through Solids.
      They are Slower.
      They Are Transverse.
  4. 4Explain S-Waves
    1. AThey only travel through Solids.
      They are Slower.
      They Are Transverse.
    2. BThey go through Solids and Liquids.
      They are faster than S-Waves.
      They are Longitudinal.
  5. 5What happens to waves when they reach different layers of earth?
    1. AThey reflect, Sometimes
    2. BThey go init.
  6. 6Do waves Change Speed?
    1. AYes, as the properties of the Mantle and Core change, it causes them to also change direction slightly - This is Refraction
    2. BNope.
  7. 7Is the speed Change of waves Gradual?
    1. AA lot of the time, it is, so it's got a curved path. But when the properties change suddenly, speed changes abruptly and so does Direction.
    2. BNo its sudden.
  8. 8What do P-waves tell us about The Mantle and Core.
    1. AP-Waves change direction abruptly about halfway down into earth, showing a sudden change in properties.
    2. BNuffin.
  9. 9S-waves are not detected in the core's shadow, what does this tell us?
    1. AThat the Outer core is liquid because S waves only go through Solids
    2. BTHat the Core is Gas.
  10. 10P-waves travel slightly faster in the core, what does this show?
    1. AThat the core is Solid.
    2. BThat the core is Gas.
