  1. 2. Sudden events that led to a mass extinction
  2. 6. Includes the crust and upper part of the mantle and is divided into tectonic plates
  3. 9. Formed as a result of high temperature and pressure deep within earth changing a rock that already existed
  4. 10. Forms after weathering and erosion when sediments compact and cement
  5. 12. Rock formed when lava or magma cools and hardens
  6. 13. Fractures or zones of weakness in the Earth's crust
  7. 15. Hot material rises, cooler materials sink. It drives plate tectonics
  8. 17. Deep, elongated depressions in the ocean, often associated with subduction zones.
  9. 18. located between the mantle and the outer core
  10. 20. where tectonic plates slide past each other. Causes earthquakes.
  11. 21. formed at plate boundaries platesly when plate collide.

  1. 1. The semi-fluid layer of the mantle where convection currents happen.
  2. 3. Name of the acient supercontinent when it was all one landmass.
  3. 4. tectonic plates move away from each other usually forms new crust and rift valleys.
  4. 5. Extinction events that occur over a longer time period
  5. 7. new oceanic crust is formed as tectonic plates pull apart and magma rises.
  6. 8. A group of the same species living in the same area
  7. 11. Instruments used to measure and record seismic waves
  8. 14. tectonic plates move toward each other usually forms mountains and volcanoes
  9. 16. Large rigid pieces of the Earth's lithosphere that move and interact with each other along plate boundaries
  10. 19. an opening in the Ethrough crust though which molten rock is pushed out and created new rock
