Review for Earth’s Interior, Plate Tetonics, Seafloor Spreading QUIZ
Prentice Hall Chapter 1 (pages 6-40)
You may want to also reread your notes and book sections to fully be prepared for quiz.
How did the mystery film canister activity relate to what Earth Scientists do?
How do scientists know what kinds of layers there are in the Earth? (rock samples, seismic waves,
etc.)
What’s the difference between the lithosphere and the asthenosphere? What are they known as?
How does “ooblek” (i.e. cornstarch plus water) compare to the asthenosphere? What’s so special
about it?
What’s the difference between oceanic and continental crust? What are they mostly made of?
Name ALL of the layers and sublayers of the Earth from insides out – explain important facts about
each layer. (crust, oceanic crust, continental crust, mantle, outer core, inner core, asthenosphere,
lithosphere)
Why does the Earth have a magnetic field?
What happens to the temperature as you go deeper into the Earth? What about the pressure?
Draw a complete diagram of convection and explain it. Where do convection currents occur on/in
Earth?
Be able to name, describe, and give examples of three types of heat transfer. (Page 15 of your book)
Who came up with the idea of continental drift? Explain what the theory of continental drift is.
What are the four pieces of evidence that back up the idea of continental drift (Pangaea’s existence)?
What is the supercontinent called and what does it mean?
What is a mid-ocean ridge?
What is a rift valley? Draw a picture.
What is the theory of seafloor spreading?
Who came up with the theory of seafloor spreading?
What are the three pieces of evidence that show seafloor spreading is real?
Describe evidence from molten material. Make sure to explain why it actually shows that seafloor
spreading is happening.
Describe evidence from drilling samples.
Describe evidence from magnetic stripes.
When was the last time the Earth’s magnetic field changed?
Describe subduction and where it happens.
What does density have to do with seafloor spreading?
What is happening to the Atlantic and Pacific Oceans – describe why in detail.
Draw a diagram that shows seafloor spreading.
Is the Earth getting bigger, smaller, or neither because of seafloor spreading? Explain.
What are lithospheric plates?
What are plate boundaries?
Describe and draw the three types of plate boundaries. Give examples of where you can find these.
What happens when two oceanic plates collide? Two continental plates? One oceanic and one
continental?
What are “plates” in Earth science? What layer are they and what are they floating on?
What is the theory of plate tectonics?
What specifically happens at a divergent boundary in the ocean? What about on land? Give examples
of actual names.
What specifically happens at a convergent boundary – continental vs. continental? Oceanic vs.
continental? Oceanic vs. oceanic?
What usually happens at a transform boundary?
