Unit 2 Plate Tectonics
Across
- 2. the study of fossil magnetism in rocks
- 3. An undersea mountain chain that creates new ocean floor through diverging oceanic plates
- 6. valley created at a divergent boundary where plates are spreading apart
- 7. a hypothesis that has been tested and not found faulty
- 9. region where 2 plates are SLIDING past each other
- 10. movement of tectonic plates over time
- 12. sections of lithosphere that the Earth's surface is divided into
- 13. region where 2 plates are COLLIDING
- 14. region where 2 plates are SPREADING APART
Down
- 1. the idea that over time the continents have slowly drifted apart
- 4. the supercontinent that the continental drift was based on
- 5. fixed area of the mantle where hot magma rises through the lithosphere above it
- 7. plates in the ocean separate allowing magma to rise and create new crust
- 8. A valley that lies along the bottom of the ocean at a subduction zone
- 11. process of when a denser oceanic plate moves under a less dense continental plate
