Across
- 2. Sudden events that led to a mass extinction
- 6. Includes the crust and upper part of the mantle and is divided into tectonic plates
- 9. Formed as a result of high temperature and pressure deep within earth changing a rock that already existed
- 10. Forms after weathering and erosion when sediments compact and cement
- 12. Rock formed when lava or magma cools and hardens
- 13. Fractures or zones of weakness in the Earth's crust
- 15. Hot material rises, cooler materials sink. It drives plate tectonics

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