1. Plate Tectonics Quiz
What is a tectonic plate? (part of your answer should include the part of the earth that is tectonic plates.)
What are the three kinds of plate boundaries? Names and arrows.
How is the Theory of Continental Drift different from the Theory of Plate Tectonics?

2. Why do earthquakes occur?

3. What is our goal? Today your goal is to know: Why earthquakes occur
Where earthquakes occur
What happens to the earth during and earthquake
The two types of seismic waves

4. Seismology Seismologist The study of earthquakes
A scientist who studies earthquakes

5. Where do earthquakes occur?
At plate boundaries
At faults away from plate boundaries.
What do we call a break in the earth’s crust
A Fault

6. Earthquake Zone
A place where many earthquakes occur.

7. Where we find earthquakes.
Transform Motion =
Strike-Slip Fault

8. Where we find earthquakes
Convergent Motion =
Reverse Faults

9. Where we find earthquakes
Divergent Motion =
Normal Fault

10. Two main types of deformation
Plastic
Like clay
Does not lead to an earthquake.
Elastic
Like a rubber band
DOES lead to an earthquake
Deformation
Change in the shape of rock because of stress.

11. Elastic Rebound Sudden return of deformed rock to its original shape.
Occurs when more stress is applied than the rock can take.
Energy is released as seismic waves which can cause an earthquake.

12. Seismic Waves Seismic Waves Surface Waves Body Waves
Waves of energy that travel through the earth.
Surface Waves
Waves that travel along the Earth’s Surface
Body Waves
Waves that travel through the Earth’s interior.

13. Body Waves P Waves Called Primary Waves
Travel through solids, liquids and gases
The fastest seismic waves

14. Body Waves S Waves Secondary Waves Shear Waves Second Fastest
Shear rock side to side
Second Fastest
Cannot travel through complete liquid

15. Which wave do you think causes the most damage?
Surface Wave
Body Wave

16. Surface Waves Produce motion in the upper part of the Earth’s crust.
Travel more slowly and are more destructive.
There are two types
One type produces up and down and around motion.
One type produces back and forth motion.
