  1. 2. This category of waves includes Primary and Secondary waves.
  2. 6. True or False: Geothermal energy in the lithosphere leads to earthquakes and volcanic eruptions.
  3. 8. Most well known example of hotspot volcanoes.
  4. 9. The category of seismic waves that are felt by people during an earthquake
  5. 10. Wegener’s first reason stated that all continents look like they fit together like this
  6. 15. If you have an oceanic and continental plate meet at a convergent boundary, which plate is weaker and gets pushed underneath?
  7. 16. Steep, smooth slopes. Form after violent eruptions blow fragments of rock (ash) and lava into the air. What type of volcano am I? (two words, no space)
  8. 18. Proved Wegener’s theory to be true
  9. 20. The category of seismic waves that are rarely felt by humans during an earthquake
  10. 21. Waves produced by an earthquake radiate out from its focus
  11. 22. The theory that states the Earth’s crust is broken up into "plates" that move independently over the weaker upper mantle. (two words, no space)
  12. 24. How many different convergent plate boundaries are there?
  13. 26. Gentle slopes, wide at base (flows long distances from vent). Lava is very low viscosity (runny). Less violent, more predictable. Lava can overtake farms, homes, etc. What type of volcano am I?
  14. 27. What kind of elements give off energy in the lithosphere?
  15. 28. The actual location in the earth where movement in crust originates
  16. 31. Steep, wrinkled slopes. Made of alternating layers of lava and ash. Viscous (thick) magma. Violent, explosive and unpredictable. Also known as a stratovolcano. What type of volcano am I?
  17. 33. The lithosphere is made up of the crust (oceanic and continental) + upper _____.
  18. 34. Heat energy from the earth
  19. 36. This category of waves includes Love and Rayleigh
Down
  1. 1. Magma melts the tectonic plate above, then builds and rises to surface, creating a volcanic island (two word, no space)
  2. 3. The type of plate boundary where plates spread apart
  3. 4. This kind of destruction often provides opportunities for people who live in disaster prone areas.
  4. 5. The type of plate boundary where plates slide against each other in opposite directions.
  5. 7. The point on the surface directly above the earthquake's focus
  6. 11. The path along the Pacific Ocean, that follows plate boundaries, characterized by active volcanoes and frequent earthquakes (three words, no spaces)
  7. 12. A scale to measure earthquakes that uses a numerical value, based on data collected from the seismograph
  8. 13. A visual scale to measure earthquakes, based on the destruction that occurs
  9. 14. How are volcanic eruptions measured? (short form)
  10. 17. Developed the theory of continental drift
  11. 19. Used to detect and record seismic waves
  12. 23. The type of plate boundary where plates crash into each other
  13. 25. Where plates meet
  14. 29. The number of reasons Wegener had to support his theory of continental drift
  15. 30. The crust (oceanic and continental) + upper mantle. What sphere am I?
  16. 32. Created by a release of energy stored in the plates beneath the surface, resulting in trembling or shaking of Earth’s crust
  17. 35. The crust is constantly moving because of this
