• These waves are the fastest waves.
• These waves travel through anything.
• These waves are secondary waves.
• This is the place inside the Earth where the
  Earthquake actually occurs.
• This is the place on the surface of the Earth
  directly above the Earthquake location.
• These are surface waves are very slow.
• These are only half as fast as primary waves.
• Where do the deepest Earthquakes occur?
• These waves are compressional waves.

• We are confident in our knowledge of the
  structure of the Earth. We know that it has a
  Crust, Mantle, Outer and Inner Core. This
  information has been determined using
  ________________.
• Geologists working in the coalfields of Southwest
  Virginia have be able to determine vital
  information about sub-surface(several thousand
  feet). They are interested in where one would
  find coal seams to mine. Their information comes
  from ____________________.
