Across
- 1. Molten rock inside the earth
- 4. A violent shaking of the ground caused by plate tectonics
- 6. These large, flat, pieces of the crust rub together to create earthquakes
- 8. The layer above the asthenosphere. It is composed of the crust and the hard upper mantle
- 9. A large crack in the earth at a plate boundary. They are the results of earthquakes
- 11. The rising and falling of material in the asthenosphere, these cause plate tectonics
- 12. Earthquakes happen at these types of plate boundaries
- 14. This logarithmic scale measures the amount of energy released in an earthquake
Down
- 2. This is a qualitative scale that is based on observations; measures the effects and damage of earthquakes
- 3. The thin, rocky outer layer of the earth above the mantle
- 5. The layer below the lithosphere located in the mid-upper mantle. Convection currents take place here
- 7. These are also known as L-Waves; They travel slower than body waves and cause the most damage
- 10. Plate __________ are the study of the earth's plates and their movements
- 13. The layer below the crust; this layer is the majority of the earth's mass
