Seismic Waves and Earth's Layers Vocab
Across
- 1. has properties of a liquid and a solid
- 4. the area in the crust where the earthquake started
- 5. what happens when waves hit a new layer (bending)
- 8. travel as a shear wave (side to side)
- 12. the area of earth's mantle where convection currents move the tectonic plates
- 14. these travel through the earth
- 16. the source of many seismic waves that we measure
- 19. the hottest layer of the earth
- 20. travel as a push or pull, like dominoes hitting each other
- 21. energy that travels through the earth
Down
- 2. these cannot travel through the earth, only on the surface
- 3. the property that allows different layers to form
- 6. this layer is the only truly liquid layer
- 7. If seismic waves had school pictures, they would be these
- 9. the layer we probably know most about
- 10. S-waves cannot travel through this
- 11. areas on earth that don't receive seismic waves from an earthquake
- 13. this happens when waves enter a new substance (not bending)
- 15. it's a machine, and it reads seismic waves
- 17. the area on the crust right above an earthquake
- 18. Who discovered the boundary between the crust and mantle?
