Across
- 3. volcanoes that have not erupted in historical times
- 5. a pasty lava that forms steep- sided volcanoes
- 6. a fast flowing column of hot mud
- 7. destructive plate boundary
- 8. material fired high into the sky during volcanic eruption
- 10. large depression at the top of a lava cone (not crater)
Down
- 1. the main plate around where the most tectonic activity takes place
- 2. fold mountains pushed up with the Indian/ Eurasian plate collision
- 4. Hawaii's most well known volcano
- 6. crust and upper part of the mantle
- 8. supercontinent land mass that began to break up 200 mya
