  1. 2. New oceanic crust is formed as tectonics plates pull apart from magma and rises
  2. 6. The semi-fluid layer of the mantle where convection currents happen
  3. 7. Formed at plate boundaries usually when plates collide
  4. 9. Located between the mantle and the outer core
  5. 11. Includes the crust and upper part of the mantle, and is divided into tectonic plates
  6. 15. a group of the same speciesSeismograph instruments
  7. 16. Formed as a result of high temperature and pressure deep within earth changing a rock that already existed
  8. 18. Forms after weathering and erosion when sediments compact and cement
  9. 19. Name of the ancient supercontinent when it was all one landmass
  10. 20. Tectonic plates move toward each other, uBoundaryforms mountains and volcanoes
  11. 21. Fractures or zones of weakness in the Earth's crust

  1. 1. Tectonic plates move away from each other, usually forms new crust and rift valleys
  2. 3. An opening in the Earth's crust through which molten rock is pushed out and creates new rock
  3. 4. Where tectonics plates slide past each other, Causes earthquakes
  4. 5. Hot materials rises, cooler materials sink. It drives plate tectonics
  5. 8. Deep,elongated depressions in the ocean, often associated with subduction zones
  6. 10. Instruments used to measure and record seismic waves
  7. 12. Rock formed when lava of magma cools and hardens
  8. 13. Large, rigid pieces of the Earth's lithopshere that move and interact with each other along plate boundaries
  9. 14. sudden events that led to a mass extinction
  10. 17. Extinction Events Extinction events that occur over a longer time period
