Across
- 1. Tectonics a theory explaining the earth's structure and many other phenomenons
- 3. Zone sites of down dwelling on the earth's lithosphere
- 5. Waves a seismic wave when rock particles vibrate at right angles to the direction of wave travel
- 6. Boundary an actively deforming region where two (or more) tectonic plates move toward one another and collide
- 8. result of a sudden release of a lot of energy in earths crust that creates seismic waves
- 11. Core ball of solid nickel and iron
- 14. Core A liquid ball of nickel and iron
- 15. between the crust and the outer core
- 16. Waves a seismic wave when rock particles vibrate parallel to the direction of wave travel
- 17. Floor Spreading oceanic crust is formed by convective upwelling of magma
Down
- 2. the outermost shell of a planet that is rocky
- 4. Boundary a linear feature that exists between two tectonic plates that are slowly moving away from each other
- 6. Current the movement of molecules in fluids
- 7. an end in a volume of rock as a result of earth movement
- 9. Fault a strike slip fault where a sudden change in form, displacement, or direction has occured
- 10. directly above the point where an earthquake or explosion begins/ originates
- 12. a large area of exposed Precambrian crystalline igneous and high-grade metamorphic rocks
- 13. Waves a seismic wave that travels across the surface of the earth as to through it
