Plate Tectonics
Across
- 3. Where the ocean floor plunges into deep underwater canyons over tens of millions of years
- 5. Long chains of mountain that rise up from the ocean floor
- 6. States that Earth's plates are in slow, constant motion, driven by convection currents in the mantle
- 8. Process where new molten material from inside Earth rises, erupts, cools, and hardens to form a solid strip of rock along mid-ocean ridges
- 9. Where plates slip past each other
- 10. Breaks in earth's crust where rocks have slipped past each other
Down
- 1. Where plates move apart, or diverge, from each other
- 2. Where plates come together, or converge
- 4. The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle again
- 7. Where pieces of Earth's crust diverge on land
