1 Seismic Waves- 3 Types Cornell Notes page 129

2 Surface Waves Travel slowly along Earth’s surface usually most destructive

3 Travel more quickly through Earth’s layers
2 types Body Waves

4 Body waves- 2 types: P Waves “Primary” wave Fastest wave Longitudinal compression waves Travel through both solids and liquids

5 Body Waves- 2 Types: S Waves “Secondary” waves Slower than P waves, but faster than surface waves Travel side to side (like a snake) Can only travel through solids

6

7

8 Assignment: Draw P and S waves
P Waves (primary waves) Straight ahead motion Faster than S waves Travel through all parts of Earth S Waves (secondary waves) SIDE to SIDE motion Slower moving than P waves Travel only through solids

Earthquakes.
 The shaking or trembling caused by the sudden release of energy.  Usually associated with faulting or breaking of rocks.

Seismic Waves The source of an earthquake is called the focus and the epicenter is the point on Earth’s surface directly above the focus. Seismic waves.

What causes an earthquake?  Deformation- the change in shape of rock in response to stress  Elastic Rebound- Return of rock to its original undeformed.
