Theory of Plate Tectonics
Across
- 5. plates move towards each other & collide
- 6. a prediction or statement based on limited evidence that can be tested by observation and experimentation
- 8. tectonics the scientific theory that the lithosphere is made up of rigid pieces, called tectonic plates, that move across Earth's surface
- 9. the process by which a collision between two tectonic plates forces the denser plate under the less dense plate
- 11. the requirement that must be met for an engineering solution to be successful
- 13. the hypothesis that the continents slowly drifted to their current positions after having been part of a single, giant landmass that broke apart
Down
- 1. a break in Earth's crust where the rocks on either side have moved
- 2. theory a well-established group of ideas or models that is supported by a large amount of evidence and that can be used to explain many different phenomena
- 3. plates move away from one another
- 4. the circulation of material caused by differences in temperature
- 7. the process by which the rocks on either side of the mid-ocean ridge slowly pull away from each other, allowing molten rock to rise, solidify, and form new seafloor
- 10. plates slide past each and lithosphere is neither created nor destroyed
- 11. the limitations on an engineering solution
- 12. the solid crust and upper mantle of Earth's interior
