6. Name of the ancient supercontinent when all one landmass
9. an opening in the earth's crust through which molten rock is pushed out and creates new rock
10. located between the mantle and the outer core
13. formed at plate boundaries usually when plates collide
15. New oceanic crust if formed as tectonic plates pull apart and magma rises
16. Insturments used to measure and record seismic waves
19. Formed as a result of high temperature and pressure deep within earth changing a rock that already existed
20. Tectonic plates move away from each other, usually Forms new crust and rift valleys
21. tectonic plates move toward each other, usually forms mountains and valcanoes

1. plates large rigid pieces of the earth lithosphere that move and interact with each other along plate boundaries
2. hot material rises, cooler meterals sink. It drives plate tectonics
