Unit 9- Earth's Materials & Rock Cycle
Across
- 7. the densest layer of the earth, mostly made of Fe and Ni
- 8. hot fluid below the earths crust
- 10. a substance naturally formed in earth
- 12. located in the upper most mantle, right below the lithosphere
- 14. what the earth is made up of
- 16. formed when sediments are weathered, deposited, and eroded to form a new rock
- 17. when magma or lava crystallizes, it forms this type of rock
Down
- 1. the layer made of all liquid, made of Fe and Ni
- 2. a mark (usually a line) made from the surface of a rock
- 3. it is part of the mantle and the crust, is right on top of the athenosphere
- 4. force put onto a rock
- 5. when a rock has lots of heat and pressure it forms a new rock
- 6. the thickest layer of earth
- 9. bringing together particles
- 11. igneous rocks formed from magma forced into older rocks in the earth's crust
- 13. how light interacts with the surface of a rock or crystal
- 15. the movement of a plate in the earths crust into the mantle beneath another
