    throughout time?
  • It includes the continents, but not the ocean
    floor.
  • It is a changing, moving surface with the same
    thickness everywhere.
  • It is a system of large masses called plates that
    slowly move together or apart.

5

10
  • 8. The average density of one of the continental
    crusts is 2.8 g/cm3 and the average density of
    one of the oceanic crusts is 3.2 g/cm3. If
    these two plates came together, what could be
    expected to happen?
  • The two plates would push apart and form a rift
    zone.
  • The oceanic plate would rise up over the
    continental plate.
  • The oceanic plate would be pushed under the
    continental plate.
  • The two plates would meet head on and rise up to
    form mountains

11
  • 9. If we compare the temperature and pressure of
    the Earths mantle to the core, what differences
    can we expect as we move downward into Earth?
  • Both the temperature and pressure increase
  • Both the temperature and pressure decrease
  • The temperature decreases and the pressure
    increases

    inference. Which property would be best for her
    to observe next?

  • The rocks were intrusive
  • The rocks were metamorphic

23

28
  • 2. A student wants to study how igneous rock
    changes to sedimentary rock. Is this a good
    project if the student needs to complete the
    study within a month?
  • Yes, because the changes will happen quickly and
    be significant.
  • Yes, because the changes will be easily observed
    since they are very obvious.
  • No, because the difference between igneous rock
    and sedimentary rock is not noticeable.
  • No, because the changes will take much longer
    than a month to occur.
