Across
  1. 3. This theory is supported by fossil distributions and continents being able to fit together like a jig-saw puzzle
  2. 5. These sound waves can travel through solids, and sometimes gas and liquid as well, and are caused by movements of tectonic plates
  3. 7. A molten mixture of rock-forming substances, gases, and water from the mantle
  4. 9. When oceanic and continental crust collide at a _________ boundary, subduction occurs
  5. 11. Strong, lower part of the mantle, rigid due to great pressure
  6. 13. The middle/largest layer of Earth, made of ultramafic rock
  7. 14. This is used to detect objects or shapes of the ocean using soundwaves
  8. 15. Lava that is formed in the shape of a _______ underwater near Mid-Ocean Ridges
  9. 22. Strange process where Earth's magnetic field periodically flips with no pattern to the frequency
  10. 23. This method of dividing Earth's layers involves using their physical properties rather than compositional
  11. 24. This plate boundary forms mid-ocean ridges and rift valleys
  12. 25. This protects the earth from dangerous radiation from the sun
Down
  1. 1. These currents bring hot, solid rock outward and cooled, solid rock inward in the Mantle
  2. 2. I gathered evidence for my theory of Continental Drift
  3. 4. This type of curst is much older than oceanic crust and is made of mostly granite
  4. 6. I made hand drawn maps of the cross-section of the ocean floor, and was called "girl talk"
  5. 8. A layer of the Earth located in the Upper Mantle underneath the Lithosphere
  6. 10. A curved chain of islands that is in the shape of an ___, created at convergent plate boundaries Example: Aleutian Islands
  7. 12. One type of dark colored rocks that make up Oceanic Crust
  8. 16. Dark colored rock known for its magnetic properties
  9. 17. Continental crust is mostly made of this type of rock
  10. 18. One way to divide the layers of the Earth using the chemical composition
  11. 19. With very high temperatures and pressure, this layer of the earth to act like a solid
  12. 20. The shaking that results from the movement of rock beneath Earth's surface
  13. 21. Outermost, thinnest layer of the Earth that contains all land features
  14. 26. The rigid crust of the upper layer of the mantle, broken up into tectonic plates
