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