Across
- 4. water held underground in the sol in deep reservoirs
- 5. when heat, pressure, cooling, melting, and weathering causes rocks to change from one form into another
- 6. occurs when divergant plates separate
- 8. the outer layer of the earth. includes crust and upper mantel
- 9. the supercontinent that existed before continents separated
- 10. no longer in existence
- 12. petroleum, natural gas, coal. made from remains of plants & animals
- 14. where tectonic plates colide
- 19. where one plates subduncts under another and magma underground, is pushed up
- 20. move side to side through solids ONLY. travel slower than p waves.
- 22. where tectonic plates divide
- 23. a solid inorganic material found in nature
- 25. hawaiian islands were formed this way
- 27. still in existence, surviving species
- 28. when a sudden release of energy in the lisophere creates seismic waves
- 30. group of animals that occupy a certain area
Down
- 1. the lower part of the earths mantle hotter and more fluid part of mantle
- 2. the movement cause within a fluid when hotter less dense material rises and and colder denser material sinks
- 3. solid most outer layer part of earth
- 7. a tool that meaures/records details of earthquakes
- 9. compress or squeeze through solids and liquids. faster that s waves
- 11. large pieces of lithosphere that the ocean & continents rest on
- 13. forms when molten rock crystallized and solidifies
- 15. the study of the earth
- 16. where tentonic plates slide past each other
- 17. the innermost part of earth
- 18. forms under extreme heat and pressure. appears twisted
- 21. forms from preexisting rock an fossils appears layered
- 24. the lower part of earths mantle
- 26. the layer that lies between the earths crust and core
- 29. the study of earthquakes and related phenomena
