  • 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 ____________________.

  • Recent studies of the Mantle have indicated that
    it is much more complex that originally thought.
    This new information has been revealed using
