Across
- 3. the more dense tectonic plate sinking beneath the less dense plate at a convergent boundary
- 5. the youngest crust created on the sea floor from a divergent boundary
- 9. the densest layer of the earth
- 10. what drives the movement of the tectonic plates by transferring heat through the asthenosphere
- 11. two tectonic plates sliding past one another causing earthquakes
- 12. made up of the crust and the upper part of the mantle
Down
- 1. the part of the mantle that is plastic and flowing
- 2. when two tectonic plates collide into each other
- 4. two tectonic plates pulling away from each other, creating a rift zone
- 6. the pieces that earth's crust is broken in to
- 7. the layer of the earth that is completely molten
- 8. created when two oceanic plates collide and the denser one subducts
