Across
- 3. occurs when two tectonic plates move away from each other
- 5. large slabs of rock that divide earth’s crust
- 8. is an important phenomenon of our earth system
- 10. giant waves caused by earthquakes or volcanic eruptions under the sea.
- 13. causes a fault between two plates of the lithosphere which will slide past one another
- 14. releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
- 16. What changes as a result of the independent variable manipulation in experiments
- 18. making an observation, forming a hypothesis, making a prediction, conducting an experiment and finally analyzing the results
- 19. long, narrow depressions on the seafloor that form at the boundary of tectonic plates where one plate is pushed, or subducts, beneath another.
- 20. is most remembered as the originator of continental drift hypothesis
Down
- 1. molten material moves in at the boundaries between tectonic plates pushing them apart as new oceanic crust is created
- 2. that stands alone and isn’t changed
- 4. scientific study of the deformation of the rocks that make the earth’s crust and the forces that produce such deformation
- 6. that’s held constant in a research study
- 7. calculate water depth by measuring the time it takes for the acoustic signal to reach the bottom and the echo to return to the ship.
- 9. outermost rocky shell of a terrestrial planet or natural satellite.
- 11. when two plates come together
- 12. made of solid rocks and minerals
- 15. the mostly solid bulk of Earth's interior
- 17. hot vapor, and gas are being or have been erupted from the earth's crust.
