Guiding Questions

• Describe the Earths internal structure. How do
  we know about the insides of the Earth even
  though we cannot go to the center of the Earth?
• Why arent the Earths craters spread evenly over
  the Earths crust (even if we look only at the
  solid surfaces)?
• Why does the Earth have so few craters compared
  to other solid bodies in the solar system?
• Where on Earth will you find shield volcanoes?
  What is the cause of shield volcanoes?
• Where on Earth will you find stratovolcanoes?
  What is the cause of stratovolcanoes?
• Describe the pattern of the Earths volcanoes.
  Why arent they spread randomly across the
  surface?
• Differentiate between plain old tectonics and
  plate tectonics.
• What are four different types of plate
  boundaries, and what kinds of features do we see
  at each?
• What is the cause of plate tectonics?
• What is the evidence for plate tectonics?
