Plate Tectonics

1. The liquid layer deep within the earth
3. A large wave caused by an earthquake or another disturbance
6. a supercontinent that incorporated all the land on Earth
9. The mostly solid interior of the Earth and the largest layer
13. a fast moving mud flow that destroys everything
14. the scale that measures the magnitude of an earthquake
15. when the magma heats within the mantle it uses a process to move the plates
17. The deepest layer, solid and is very hot
18. a large slab of rock or parts of the crust which moves slowly, they interact with other plates differently
21. a well established explanation with a lot of backing evidence
23. deadly ash produced from a volcano, can kill crops
26. a highly viscous, weak and ductile region of the upper crust
29. a storage of magma within a volcano
30. when two plates move away from each other

2. path along the Pacific Ocean with many active volcanoes and frequent earthquakes
4. deadly gases produced from an eruption, can damage the lungs
5. hot molten rock on the surface of the crust
7. A sudden violent shaking of the ground caused by the sudden release of energy along a fault of a plate
8. fast moving flow os solidified lava pieces
10. when two plates slide across each other
11. vents or openings in the Earth's crust, that release ash, gas, steam and hot liquid rock called lava
12. when two or more plates collide
16. can produce sediment through the weather
19. Thin shell on the outside of the Earth
20. hot molten rock beneath the Earth's surface
22. when volcanic gases mix with the rain it creates rain that can kill crops
24. the rocky outer part of the Earth, made up of the brittle crust
25. an opening in the volcano where the magma can exit
27. scientist who proposed the theory of plate tectonics
28. when a plate move under another
