- 9. This is the name for the landmass comprising all modern continents.
- 11. This is where an oceanic plate subducts under a continental one.
- 12. Another word for Gravity Pull.
- 13. This man created the plate tectonic theory.
- 15. This is the layer that the crust is floating upon.
- 16. This is the term for the transfer of thermal energy by heated matter.
- 18. This is important because its role is both the movement of continents and the distribution and evolution of species.
- 20. This is a type of tectonic plate on earth.
Down
- 1. This plate boundary is when two tectonic plates move apart.
- 2. This plays a role in preventing a runaway greenhouse effect.
- 4. This is the movement of the Earth’s tectonic plates caused by.
- 5. This does NOT act as evidence for the theory of plate tectonics.
- 7. This results from tectonic plates quickly sliding against each other at sites where strain has built up.
- 8. In the event of two continental plates moving part, this is what it's called.
- 10. The name for the process of one plate going under another.
- 14. This type of sound wave is used to observe the seafloor.
- 17. This is the rate that the earth's plates move.
