1. What sets the continental plates in motion? Describe the process.
2. Briefly explain the difference between Converging, Diverging and Transform
Fault boundaries.
3. Give 1 evidence of sea-floor spreading that scientists have?
4. Give 2 reasons why diverging tectonics are less violent than converging
tectonics?
5. What causes the narrow valleys along a fault line?
6. What is fault creep?
7. Explain what it means when the plates are locked. What is the result then?
8. How do laser sensors, seismographs and strain gauges help scientists detect and
predict earthquakes?
9. What are the two types of converging plate boundaries?
10. Describe how it is possible for one plate of rock to descend beneath another. Ie,
what are the elements necessary to allow that to happen?
11. Briefly describe what happens when two plates collide and neither of those plates
is able to descend beneath the other?
12. Explain why some volcanoes are more spectacular and destructive than others.
13. What is the difference between continental volcanic arcs and island arcs?
14. Scientists speculate ocean floor rock is much younger that continental rocks. Why
would ocean floor rocks be younger?
15. Cratons are described as the roots of mountains. Explain
16. Briefly describe 2 processes of accretion.
