plate tectonics and earth dynamics
Across
- 3. the rigid outermost layer of Earth that includes uppermost mantle and crust.
- 4. super continent that broke apart 200 million years ago
- 5. the circulation of particles within a material caused by difference in thermal energy and density
- 6. the pulling force at a divergent boundary
- 8. a change in the shape of rack caused by stress
- 10. deep underwater trough created by one plate subducting under another at a convergent boundary
- 11. an area of many fractured pieces of crust along a large fault
- 15. fault that forms where tectonic plates slide horizontally past each other
Down
- 1. parallel forces acting in opposite direction at a transform boundary
- 2. the squeezing force at a convergent boundary
- 7. the downward vertical motion of Earth's surface
- 9. a curved line of volcanoes that forms parallel to a plate boundary
- 12. the process that moves large bodies of Earth's materials to higher elevations
- 13. the equilibrium between continental crust and the denser mantle below it
- 14. the process that occurs when a tectonic plate moves under another
