Across
- 2. the layer between core and crust.
- 4. forms from pre-existing rocks
- 5. release of energy that creates seismic waves
- 7. Petroleum, natural gas, coal. Made from animal and plant remains
- 9. the continent we now know as North America was contiguous with Africa, South America, and Europe.
- 10. Magma flows from underground.
- 13. lower part of earth
- 14. When two plates come together
- 15. a solid inorganic material found in nature
- 18. Plates slides past the other Plate.
- 23. When magma flows from a crack.
- 24. a tool that measures earthquakes
- 25. the innermost layer of earth.
- 27. compress or squeeze through solids,liquids faster than s waves
- 28. no longer in existence
- 29. forms when molten rock crystallizes
- 30. occurs when two tectonic plates move away from each other
Down
- 1. Larger pieces of lithosphere
- 3. outer part of earth
- 6. group of animals that occupy a certain area
- 8. forms under extreme pressure
- 11. the study of earth
- 12. the formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side.
- 16. still in existence
- 17. outer most part of earth
- 19. when heat pressure cooling melting and weathering cause rocks to change from one type to another over time.
- 20. water held under ground in the soil in deep reservoirs
- 21. the movement caused within a fluid
- 22. the study of earthquakes
- 26. Moves side to side only goes through solids.
