Across
- 4. - Upper layer of the Earth’s mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur
- 5. - Vibrations that travel through Earth carrying the energy released during an earthquake
- 7. - Dense sphere of solid iron and nickel at the center of Earth
- 11. - Rigid layer made up of the uppermost part of the mantle and the crust
- 12. - Thin and solid outermost layer of the Earth above the mantle
- 13. - Heat energy transfer between two parts of a fluid of different temperatures. When hot fluids rise and cold fluids sink.
- 15. (continental/continental) - When two continental plates collide creating mountains
Down
- 1. Boundary between tectonic plates that are sliding past each other
- 2. a molten mixture of rock-forming substances, gasses, and water from the mantle
- 3. - A plate boundary where two plates move away from each other.
- 6. - Portion of the Earth’s crust that primarily contains granite, is less dense than oceanic crust, and his 20-50 km thick
- 8. - Layer of molten iron and nickel that surrounds the inner core of the Earth
- 9. - Theory that great slabs or plates of Earth’s outer layer float on a hot, semi-molten mantle.
- 10. - Earth’s crust located under the ocean
- 14. - the layer of the Earth between the core
