1. Let’s Review Convection!
Who proposed the theory of Continental Drift? Answer IS...(click here)
What is the process which causes the plates to move?
Convection!

2. Divergent Boundaries Plates pull apart.
Put your hands over your head and pull
apart.

3. Convergent Boundaries
Push together
BRAIN BREAK
Do the convergent Kung Fu Panda move put your palms together and rise.
What is formed? Sometimes one plate slips under the other in subduction. Do this move with your hands.

4. Effects of crustal plate movement!

5. Transform Fault Boundaries
Boundary between two plates that are sliding past each other
EARTHQUAKES occur along faults
Faults are breaks in the Earth’s crust where rocks have slipped past each other.

6. Slide Sideways Slide Sideways
two plates grind together past each other often causing earthquakes. Ex. San Andreas Fault (California)

7. San Andreas Fault in California
Mrs. Burns used to live a few miles from the San Andreas fault. Her husband looked at it out his office window at work. Palm trees grow along the fault line. This picture is taken from high up in space.

8. Make Your Own Earthquake
Snap your fingers and observe what is happening.
When you snap your fingers, imagine that each finger is a big chunk of rock deep inside the Earth’s surface. Like your fingers, one rock mass is forced against another.

9. Earthquake Destruction-click
Writing Reflection (in notebook):
Why do earthquakes in other countries seem to cause more damage and casualties than earthquakes in the US? What can Americans do about it?
Rain to write to

10. Where do earthquakes occur?

11. What happens when you throw a rock into water. Why does it ripple
What happens when you throw a rock into water? Why does it ripple? How far do the ripples continue? How might this relate to Earthquakes?
VIBRATIONS
An instrument called a seismograph records tectonic plate movement.
A seismologist is a scientist that studies earthquakes.
Aftershocks are smaller vibrations after a large earthquake
