Across
- 2. Move side to side through ONLY solids
- 4. No longer in existence
- 8. Occurs when divergent plates seperate
- 11. Boundary where tectonic plates slide past each other
- 12. Form at convergent boundaries where one plate subducts under another, and magma underground is pushed upward
- 14. The lower part of the Earth's mantle, Below the Asthenosphere
- 15. Forms under extreme heat and pressure, Appears twisted
- 17. The solid, outermost layer of the earth, lying above the mantle
- 20. The movement caused within a fluid when the hotter less dense material rises, and colder, denser material sinks
- 21. Boundary where tectonic plates collide
- 22. The study of Earth
- 23. Below the lithosphere. Hotter and more fluid part of the mantle
- 25. heat,pressure,cooling,melting,etc.
- 27. Petroluem, Natural Gas, Coal
- 29. The layer that lies of the earths crust crust and core. The majority of Earth's mass is in this layer
- 30. Boundary where tectonic plates divide
- 31. Forms when molten rock crystallizes and solidifies
Down
- 1. Compress or squeeze through solids and liquids
- 3. The study of earthquakes
- 5. A tool that measures/records details of earthquakes
- 6. Still in existence
- 7. The outer part of the earth. Includes the crust and upper mantle
- 9. Group of animals that occupy an area
- 10. When magma flows through a crack in the middle of tectonic plate, and not at a plate boundary. Hawaiian islands were formed this way
- 13. water held underground in the soil
- 16. The innermost layer of the earth. Divided into 2 parts, liquid outer and solid inner
- 18. Large pieces of lithosphere that the ocean and continents rest on
- 19. The supercontinent that existed before continents seperated
- 24. When a sudden release of energy in the lithosphere creates seismic waves
- 26. A solid inorganic material found in nature
- 28. Forms from pre-existing rock and fossils
