1. Earthquake Notes
Warm up:
How do you think earthquakes happen? Does an entire area start shaking all at the same time or does the earthquake start in one place and finish in another? Justify your answer.
LT: I will the how earthquakes work. The purpose is to identify Earth’s forces. Today I will learn about earthquakes.
CW: Real Time Data.
Concept Maps, Earthquakes
HW: None

2. Label each plate

3. Review continues…. 1. Two plates collide with each other at
Divergent boundary
Convergent boundary
The boundary between the mantle & the crust
A transform boundary
2. Volcanoes can occur at subduction zones. True or False
3. What type of boundary is this picture?
4. What type of boundary forms mountains?

4. Get Into 11 groups…..

5. Real Time Data Worksheet Review
Q1. How are earthquakes distributed? If there is a pattern, how would you describe it? Are they located near the edges of the continents, mid-continent, in the ocean?
Q2.Where is there no earthquakes?
Q3. How are volcanoes distributed? If there is a pattern, how would you describe it? Are volcanoes located near the edges of the continents, mid-continents or in the ocean?
Q5.Where is there no volcanoes?

6. Q6. What geographic features (mountains, plains, valleys, etc) are frequently found where there are only: Earthquakes?
Q7. What geographic features (mountains, plains, valleys, etc) are frequently found where there are only: volcanoes?
Summarize the relationships you discovered. Are the geologic events you looked at (earthquakes and volcanoes) more commonly found together or separate?

7. Q9. Why does volcanism occur at convergent boundaries but not at transform boundaries?
Q10. Do you observe a relationship between geographic features and plate boundaries?
 Q11.(Inferring) What would happen if the mantle wasn’t moving due to convection current?
Q12.(Inferring) A friend of yours says there is going to be a huge earthquake in Denver. Explain why this is highly unlikely.

8. Wave Movement 1. Together, we will do “The Wave”.
2. Everybody lines up shoulder to shoulder.
3. You move only when the person on your left moves, etc.
4. Practice the wave a few times.

9. Wave Movement
First we will move just our hands a few inches up and down.
Then only are arms up and down.
Then are whole bodies up and down.

10. Wave Movement
What’s changing? The height of the wave (measured from the centerline) is called amplitude.
Do a small amplitude wave.
Do a large amplitude wave.

11. Do a small wave….

12. Do a large wave

13. Longitudinal Wave
Discuss: Notice, these have all been transverse waves. Everyone’s motion is up and down, but the waves move sideways. How could we model a different kind of wave?

14. Longitudinal Wave Version 1(lite version) Version 2 (rowdy version)
Have everyone hold hands and pass a hand squeeze down the line.
Version 2 (rowdy version)
Have everyone stand shoulder to shoulder and pass a shoulder push (shove) down the line.

18. Richter Scale
Can you compare our demonstration with the Richter scale?
What would happen if you lived 15 miles from a plate boundary? Do you think you could still experience earthquakes?
What do you think about people living on plate boundaries?

21. Haiti Earthquake mag

22. Japan Earthquake mag

23. Where are the most earthquakes found?

25. Ring of Fire

26. The Pacific Ring of Fire, or just Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes.[1] About 90%[2] of the world's earthquakes and 81%[3] of the world's largest earthquakes occur along the Ring of Fire. Also, many of the world's volcanoes are located here.

27. Questions:
What types of boundary is generally associated with earthquakes?
Do you think earthquakes could happen as a result of any other plate motions? Why or why not?
Explain how an earthquake works. How does the vibration of the earthquake get from one area to another?
What do you think determines the magnitude (the strength) of an earthquake?
What kind of science vocabulary can you add to your first answer?
What new things did you learn?

28. Exit ticket
A friend says that there is going to be an earthquake in the Denver area measuring a 4.7 on the Richter scale. Use your science knowledge to explain to your friend how this is highly unlikely.

29. Do you know A, B & C? B A C Divergent – mid ocean ridge Convergent
Convection currents

30. Hot spots what are they?
Location in Earth’s surface that experiences hot magma seeping up through the Earth’s crust for a long period of time….

31. Hot Spots

32. So what is a hot spot?

33. Yellowstone National Park
