1. QQ: Conclusion of yesterday’s lab
What are the types of waves you studied?
How are the types of waves alike?
3. How are the types of waves different?
What difference do
you predict this makes
studying earthquakes?

2. Do the red dots move?
What is moving?

3. Today’s Objective:
I can describe how energy is transferred through the earth.

4. The Question: How is energy from earthquakes spread?
What’s First?
The Question: How is energy from earthquakes spread?
Hyperlink map to video
Research: Map of Virginia

5. Hypothesis:
Procedure: Time movement of springs

6. Data: WAVE TYPE: TRIAL # TIME OBSERVATION (SKETCH AND DESCRIPTION) 1 23
AVERAGE
WAVE TYPE

7. ANALYIZE THE DATA:
DESCRIBE WHAT YOU NOTICE ABOUT THE 3 TYPES OF WAVES. ARE THERE ANY PATTERNS IN YOUR DATA?

8. P-Waves (Primary)
Push and pull underground rocks
Causes structures on the surface to move back and forth
Least powerful
Fast

9. S-Waves (Secondary)
Horizontal:
Rocks move from side to side
Damaging effects
Slower
Only through rock

10. L-Waves (Love) Vertical and sideways: Rocks move up and down
Occurs on surface
Fastest of all
Most destructive

11. Waves caused by movement inside the Earth
Seismic Waves
Waves caused by movement inside the Earth
Original Force: Where rocks broke
Energy being transferred down the line

12. Rocking and Rolling!

13. How can we compare the strength of one earthquake to another?

14. Measures seismic waves
Seismograph:
Measures seismic waves

15. Measures earthquakes by graphing the waves of energy
SEISMOGRAPH
Measures earthquakes by graphing the waves of energy

17. Richter Scale
Scale used to measure the strength of an earthquake using seismic waves (p-waves and s-waves) 2 or less are small 8 or larger are huge

20. Series of huge waves caused by earthquakes under the ocean
Tsunami
Series of huge waves caused by earthquakes under the ocean
Tidal
Wave

24. Splish Splash...I was taking a bath!

25. Using the triangle of a Venn diagram
Triangulation

26. Epicenter! Wal-mart Erwin 14 miles Wal-mart Fayetteville 30 miles
Wal-mart Clinton
19 miles

27. You are the seismologist.
