Plate Tectonics
Across
- 3. / The process of a less dense plate sinking below a more dense plate.
- 6. / the layer that is semi-solid and immediately below the lithosphere.
- 8. tectonics / The lithosphere is divided into large moving pieces
- 9. boundary / when tectonic plates move toward each other and collide.
- 10. / a system of ideas that explains many related observations about the natural world.
Down
- 1. boundary / When 2 tectonic plates move away from one another
- 2. / the outermost physical layer of the earth
- 4. drift / the hypothesis that today's continents were once apart of a single land mass.
- 5. spreading / process of new seafloor forming.
- 7. boundary / When 2 tectonic plates moving past one another in opposite direction.
