  3. 7. Formed at the plate boundaries usually when plates collide
  4. 10. A group of the same species living in the same area
  5. 12. Includes the crust and the upper part of the mantle, and is divided into tectonic plates
  6. 13. Instruments used to measure and record seismic waves

  1. 1. Tectonic plates move away from each other, usually forms new crust and rift valleys
  2. 2. Cycles Hot material rises, cooler material sinks... it drives plate tectonics
  3. 3. Where tectonic plates slide past each other.... Causes earthquakes
  4. 4. Plates Large, rigid pieces of the Earth's lithosphere that move and interact with each other along plate boundaries
  5. 8. Name of the ancient super-continent when it was all one landmass
  6. 9. Extinction events that occur over a longer time period
  7. 11. Deep elongated depressions in the ocean, often associated with subduction zones
  8. 14. Fractures or zones of weakness in the Earth's crust
  9. 15. Tectonic plates move toward each other, usually forms mountains and volcanoes
