- 10. plates large, rigid pieces of the earth lithosphere that moves interact with each other along plate boundaries
- 11. the semi-fluid layer of the mantle where convection currents happens
- 12. located between the mantle and the outer core
Down
- 1. sudden events that led to mass extinction
- 3. instrument used to measured and record seismic waves
- 5. rock formed when lava or magma cools and hardens
- 7. formed as a result of high temperature and pressure deep within earth changing a rock that already existed
- 9. hot material rises,cooler material sinks. its drives plates tectonics
