Inside the earth

4. - Portion of the Earth’s crust that primarily contains granite, is less dense than oceanic crust, and his 20-50 km thick
7. - 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.
11. - Earth’s crust located under the ocean
13. gasses, and water from the mantle
15. - A plate boundary where two plates move away from each other.

1. - Heat energy transfer between two parts of a fluid of different temperatures. When hot fluids rise and cold fluids sink.
2. - 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
3. - Dense sphere of solid iron and nickel at the center of Earth
5. (continental/continental) - When two continental plates collide creating mountains
6. - Rigid layer made up of the uppermost part of the mantle and the crust
8. - the layer of the Earth between the core
10. Boundary between tectonic plates that are sliding past each other
12. a molten mixture of rock-forming
14. - Vibrations that travel through Earth carrying the energy released during an earthquake
