Across
- 3. What we call lava before it comes out of the volcano
- 5. A deep cave where old sea-floor is "swallowed"
- 7. A "sleeping" volcano
- 12. This is the very hot liquid layer made of iron that is able to it spins faster than the entire Earth, which helps create Earth’s magnetic field.
- 14. The scale earthquakes are measured on
- 16. A volcano that will probably never erupt again
- 17. The orange, molten "stuff" that comes out of the volcano
- 20. A volcano of hot water
- 21. This is the hottest layer at the center of the earth. It provides the heat and energy for the rest of the layers and is solid due to the high pressure.
Down
- 1. A spot on the Earth's surface where magma comes out
- 2. The process of "swallowing" old sea-floor
- 4. A volcano that is "awake" and can erupt at any time
- 6. Plates that are coming together
- 8. Small peaks and valleys on the ocean floor where new sea-floor is made
- 9. Plates that are moving apart
- 10. Volcanoes on Hawaii are not on a plate boundary, instead they are found a weak crack in the Earth’s crust called…..
- 11. The location of the earthquake on the Earth's surface above the focus
- 13. This is the solid and outermost layer of the earth that contains the Tectonic Plates, also known as the Lithosphere.
- 15. Plates that are moving past each other
- 18. The device used to measure earthquakes
- 19. This layer of the Earth is made of molten rock and is responsible for Tectonic Plate Movement and the Cycling of Earth’s Materials through Convection.
