2. Chap 8, Sect 1&2 (Earthquakes)
Objectives:
1. What causes earthquakes?
2. Describe how energy (from earthquakes) travels through the Earth.
3. What are the important places that are noted in an earthquake?

3. Flipchart: read & do! Tech Terms: p.224-231
earthquake – the shaking and trembling that results from the movement of rock beneath Earth’s surface.
Seismology- the study of earthquakes

4.
deformation – a change in the shape of a rock in response to stress (force & tension)
elastic rebound- the sudden return of elasticity in deformed rock to its original shape (energy release like a rubber band)

5. P
Tech Terms to add to flipchart: (independent inquiry) p waves s waves surface waves focus epicenter Define & draw!

6. Tech Terms:
Types of earthquake waves:
P waves – PRIMARY…these arrive first (movement is like an accordion).
S waves - SECONDARY…these arrive second (vibrate side to side and up and down).
Surface waves- demo!

7. 8. focus – the point beneath Earth’s surface where the earthquake occurs (rock under stress breaks).
& epicenter – the point that is on the surface, directly above the focus.
