Plate Tectonics
Across
- 3. The boundary between two colliding tectonic plates
- 5. Vibration from underground movement along a fault plane
- 6. A break or crack in the Earth's surface
- 7. The branch of geology that studies earthquakes
- 8. The soft layer of the mantle
- 10. Molten rock in the Earth's crust
- 11. The edges where two plates meet
- 14. A crack in the Earth's crust through which gases escape
- 15. The boundary where two tectonic plates move away from each other
- 17. Type of volcano that is the biggest and has large gentle slopes
- 18. Type of volcano that is big, round and shaped like a cauldron
- 20. The movement of the edge of one tectonic plate under another
- 23. Simplest type of volcano, conical with low, steep sides and often found on sides of other types of volcanoes
- 25. The outermost layer of the Earth
- 26. Region formed where two plates move apart and can be found on land or the bottom of the sea
- 28. The study of the movement of Earth's crust
- 29. The theory that continents drift apart
- 31. Continental transform fault that extends through California
Down
- 1. The science of the history of the Earth as recorded in rocks
- 2. the layer between the crust and the core
- 4. The boundary where two tectonic plates slide by each other
- 9. The process that happens at mid-ocean ridges where new oceanic crust is formed through volcanoes and then gradually moves away from the ridge
- 12. When magma erupts onto the surface it is called this
- 13. Volcano that buried the ancient town of Pompeii in Italy
- 16. A long, underwater ocean ridge created by divergent boundary
- 19. The liquid layer of the Earth's core
- 21. This is the region around much of the rim of the Pacific Ocean where many volcanic eruptions and earthquakes occur
- 22. The outermost, rigid layer of the mantle
- 24. Mountains created where two or more continental plates are pushed together. The Himalayan mountains are an example.
- 27. Type of volcano that is large and has steep slopes, also called a composite volcano
- 30. A long narrow depression in a surface
