Across
- 3. Fire fragments
- 4. A summit depression typically greater than 2 kilometers in diameter, produced by collapse following a massive eruption
- 6. Dust and glass significantly alter global temperatures
- 7. Forcibly injected between strata
- 8. Magma rises through crust
- 10. Forms localized volcanic regions in the overriding plate called a hot spot
- 13. Made of hot gases infused with ash, other debris
- 15. Steep-walled depression at the summit, generally less than 1 kilometer in diameter
- 18. Lava extruded from crustal fractures called fissures
- 19. Mudflow from interaction with debris and water
- 20. Magma forcibly injected into a fracture zone or bedding plane
- 22. Resistant vents left standing after erosion has removed the volcanic cone
- 23. One to six percent of a magma by weight. Mainly water vapor and carbon dioxide
Down
- 1. Source Material for Volcanic eruptions
- 2. Occur as long, linear features, often under mountain ranges
- 3. Lava (Resembles a twisted or ropey texture)
- 5. Clouds of volcanic ash damage planes
- 9. Lava (rough, jagged blocky texture)
- 11. Amount of dissolved gases present in magma
- 12. Smaller pluton
- 14. Triggered from collapse of volcanic landfroms in the ocean
- 16. Lavas (Occuring along divergent plate boundaries on the ocean floor)
- 17. Badsaltic lavas are much more fluid
- 21. The resistance to flow
- 22. Opening connected to the magma chamber via a pipe
