Andrea's plate tectonics

1. a crack in the tectonic plate that shows on earths surface
3. slow moving wave
5. a delay between tasks that have a dependency
6. a large plume of hot mantle material rising from deep within the Earth
9. a big wave caused by an earthquake
13. an elastic wave generated by an impulse such as an earthquake or an explosion
14. where a earthquake originates
17. the very center of the Earth and the hottest part of the planet.
18. boundary where 2 plates meet
19. the third layer and is responsible for Earth's magnetic field

1. directly above epicenter
2. the mostly-solid bulk of Earth's interior and made up of magma
4. when the earth starts shaking its called a (blank)
7. fast moving wave
8. boundary when 2 plates pull apart
10. occurs when an oceanic plate runs into a continental plate and slides beneath it.
11. a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements
12. a long narrow hilltop, mountain range, or watershed
15. boundary where two plates slide pass another
16. top layer, what we call the ground
