Across
- 2. - Earth’s crust located under the ocean
- 4. - Layer of molten iron and nickel that surrounds the inner core of the Earth
- 6. - Rigid layer made up of the uppermost part of the mantle and the crust
- 9. a molten mixture of rock-forming
- 10. - Vibrations that travel through Earth carrying the energy released during an earthquake
- 11. - Dense sphere of solid iron and nickel at the center of Earth
Down
- 1. - 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. study the internal structure of the Earth and try to determine factors that contribute to or foretell an earthquake.
- 5. - Theory that great slabs or plates of Earth’s outer layer float on a hot, semi-molten mantle.
- 7. - Portion of the Earth’s crust that primarily contains granite, is less dense than oceanic crust, and his 20-50 km thick
- 8. - the layer of the Earth between the core
