Across
- 2. plate the broken up pieces of the lithosphere
- 4. boundary- boundary between 2 plates moving away from each other (separate , divide )
- 6. occurs when 2 tectonic plates collide, and one plate moves under the other & sinks into the mantle
- 9. spreading the process of new oceanic crust forming as magma rises toward the surface and solidfles
- 10. boundary- boundary formed by collision of 2 plates ( collide, crash, collision)
Down
- 1. drift hypothesis that the continents once formed a single land mass, broke up, and drifted to the present location
- 3. boundary-boundary between 2 plates that are scraping past each other (slide, scrape)
- 5. the land mass that existed when all continents were joined together
- 7. places where tectonic plates meet
- 8. of plate tectonics- theory explaining how tectonic plates move and change shape
