Science project

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

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.
