Across
- 2. core: the solid super hot center of the earth made of mostly iron and nickel
- 4. boundary: a place where two tectonic plates push together
- 6. spot: a place where magma rises from deep inside earth, forming volcanoes
- 8. boundary: a place where two tectonic plates move apart
- 10. the thickest layer of earth between the crust and the core it has hot moving rock that slowly circulates, like thick soup
- 11. crust: the part of earth's crust that forms land
- 12. field: the invisible force around the earth that protects us from the sun's radiation

- 15. boundary: the edges where tectonic plates meet
- 17. the rigid, outermost shell of the Earth, encompassing the crust and the solid, brittle portion of the upper mantle.
- 18. something melted due to extreme heat like lava from a volcano
Down
- 1. boundary: a place where two tectonic plates slide past each other causing earthquakes
- 3. plate: a large piece of earth's crust that carries land
- 5. core: the liquid layer around the inner core is also made of iron and nickel
- 7. the flowing layer of the mantle that allows the tectonic plates to slide around.
- 9. plate: a huge piece of the lithosphere that moves on the asthenosphere
- 13. plate: a tectonic plate under the ocean, it is thinner but denser than a continental plate
- 14. the thin outermost layer of earth where we live
- 16. trench: a deep valley in the ocean floor, formed when one plate sinks under another
