Layers of Earth
Across
- 3. the movement of thermal energy through liquids and gases
- 7. a layer of molten (melted) iron and nickel that surrounds the inner core
- 9. The shaking that results from the movement of rock beneath Earth's surface.
- 10. a light colored igneous rock having large crystals; makes up most of Earth's crust
- 11. the transfer of thermal energy by direct contact between objects
- 12. force exerted on a surface divided by the total area over which the force is exerted
- 13. a dense sphere of solid iron and nickel at the center of the Earth
- 14. the thin layer of rock that forms Earth's outer surface
- 16. the soft layer of the mantle, on which the lithosphere floats
- 17. The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations.
- 18. a dark, dense igneous rock with a fine texture, found in the oceanic crust
Down
- 1. a rigid layer made up of the upper part of the mantle and the crust
- 2. A trace of an ancient organism that has been preserved in rock.
- 4. the amount of mass of a substance in a given volume
- 5. A weak spot in the crust where magma has come to the surface.
- 6. thermal energy that travels in waves and can pass through empty space as well as some objects
- 8. the layer of hot rock (solid material) between the crust and the core
- 12. The name of the single landmass (super continent) that broke apart 200 million years ago and gave rise to today's
- 15. vibrations that travel through Earth carrying the energy released during an Earth quake
