Plate Tectonics
Across
- 3. when an oceanic plate runs into a continental plate and slides beneath it.
- 4. Discovered that the continent's movement was caused by the seafloor spreading.
- 5. a continuous body of salt water that is contained in enormous basins on Earth's surface.
- 8. extremely hot liquid and semi-liquid rock located under Earth's surface.
- 11. the solid, outer part of Earth.
- 14. Two tectonic plates that are moving away from each other.
- 15. the process of deformation that produces the earth's continents, ocean basins, mountains, folds, and faults.
- 17. a massive, irregularly shaped slab of solid rock.
- 18. a continuous slow movement from one place to another.
- 19. Creator of the continental drift theory.
Down
- 1. an opening in the earth's crust through which lava, volcanic ash, and gases escape.
- 2. long-term shifts in temperatures and weather patterns.
- 6. any sudden shaking of the ground caused by the passage of seismic waves through Earth's rocks.
- 7. a fracture or zone of fractures between two blocks of rock.
- 9. a landform that rises prominently above its surroundings.
- 10. Two plates sliding past each other.
- 12. one of Earth's seven main divisions of land.
- 13. massive bodies of slowly moving ice.
- 16. the movement of the plates that make up Earth's crust.
- 17. a supercontinent that incorporated almost all the landmasses on Earth.
