Across
  1. 6. Scale, 1-10 Scale used to measure the strength of an earthquake
  2. 8. Plate, Large section of bedrock located between fault lines
  3. 9. Melted rock beneath earth’s surface
  4. 11. Melted rock above earth’s surface
  5. 13. Boundary, An area where two or more tectonic plates meet
  6. 16. Eruption, When a volcano releases molten lava, hot rock fragments, and gases onto the Earth's surface or into the atmosphere
  7. 18. Spreading, The process that forms new oceanic crust along divergent boundaries
  8. 19. Crust, The layer of crust or bedrock located under the earth’s seven continents
  9. 20. Zone, Convergent boundary where an oceanic plate slides under a continental plate
  10. 21. Rock behaving like warm clay due to extreme temperature and pressure
  11. 22. The amount stuff in a sample vs the volume of the sample (how tightly packed together the molecules in a sample are)
  12. 23. Zone, Convergent boundary where two continental plates are pushing against each other forcing the rock up
  13. 24. A supercontinent that existed a long time ago in which all current day continents were joined together
  14. 25. The outermost layers of earth made of solid rock - spans from what we can see on earth’s surface to a few miles below the surface
  15. 26. The strength of an earthquake
  16. 27. Loose earth materials, such as sand, soil, and rocks found at earth’s surface
Down
  1. 1. To break down
  2. 2. Boundary, Boundary where two plates move away from each other
  3. 3. Solid rock underneath loose soil and sediment in the earth’s crust
  4. 4. Crust, The type of bedrock or crust lying under the oceans of the world
  5. 5. Trench, A long narrow, deep area on the ocean floor formed at convergent boundaries
  6. 7. A sudden and violent shaking of the ground caused by the shifting of rock within the earth's crust or volcanic action
  7. 8. Boundary, Two plates sliding past each other
  8. 10. To build up
  9. 12. An opening in Earth's crust through which lava, ash, and gases erupt.
  10. 14. The layer of earth between the crust and the core made of thick gooey rock and magma - The creep zone is located here
  11. 15. Ridge, Underwater mountain range formed when magma fills the space along a divergent boundary
  12. 17. A crack or fracture in earth’s crust
  13. 21. Boundary, Boundary where two plates are pushing towards each other
