6. when two or more plates collide
7. a large slab of rock or parts of the crust which moves slowly, they interact with other plates differently
10. when two plates move away from each other
11. The deepest layer, solid and is very hot
12. scientist who invented the theory of plate tectonics
14. a well established explanation with a lot of backing evidence
15. hot molten rock on the surface of the crust
16. hot molten rock beneath the Earth's surface

1. a highly viscous, weak and ductile region of the upper crust
2. the scale that measures the magnitude of an earthquake
3. vents or openings in the Earth's crust, that release ash, gas, steam and hot liquid rock called lava
4. when two plates slide across each other
5. The liquid layer deep within the earth
6. Thin shell on the outside of the Earth
8. A sudden violent shaking of the ground caused by the sudden release of energy along a fault of a plate
9. the rocky outer part of the Earth, made up of the brittle crust
13. The mostly solid interior of the Earth and the largest layer
14. A large wave caused by an earthquake or another disturbance
