Earth's Layers and Rock Cycle
Across
- 3. formed within Earth’s crust when magma cools and hardens
- 4. cycle process by which rocks continually change from one rock type to another
- 7. consists of inner and outer layers (~15% of Earth)
- 8. through a geological process
- 10. largest layer (~84%) of Earth
- 11. hard, rigid outermost layer of Earth (the outer “skin”)
- 12. forms as magma or lava cools and solidifies
- 15. any solid mass of mineral or mineral-like matter that occurs naturally as part of
- 16. formed when sediment goes through compaction and cementation
- 17. small pieces of rock or living things, formed through the processes of
- 18. the breaking down of rocks
- 19. thinner crust, more dense crust (mostly basalt)
- 21. solid iron or nickel layer, moon sized
Down
- 1. thicker crust, less dense crust (mostly granite)
- 2. hard,rigid layer (bottom of crust PLUS top of mantle=plates)
- 5. only true liquid layer
- 6. and erosion
- 8. the removal of the material
- 9. field created by rotation of inner and outer cores
- 13. formed on Earth’s surface when lava cools and hardens
- 14. formed when a parent rock is put under extreme pressure or heat
- 20. heat driven cycles that occur in the mantle caused by differences in
