Seismic Waves- 3 Types Cornell Notes page 129

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

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

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

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

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
