Across
- 2. tectonics states earth's surface is made up of giant, moving slabs called tectonic plates.
- 3. The process of a less dense plate sinking below a more dense plate.
- 7. plates The lithosphere is divided into large moving pieces
- 8. the layer that is semi-solid and immediately below the lithosphere.
- 10. boundary when tectonic plates move toward each other and collide.

- 1. spreading process of new seafloor forming.
- 4. drift the hypothesis that today's continents were once apart of a single land mass.
- 5. the outermost physical layer of the earth
- 6. boundary When 2 tectonic plates move away from one another
