Plate Tectonics
Across
- 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
Down
- 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
