Volcano Science

5. a volcano that has not erupted in recorded history
8. equipment used to measure movement/activity within the crust
10. a volcano with no potential for eruption.
12. an opening in the Earth's surface where lava flows
13. a measure of a wave from crest to crest and indirectly proportional to the frequency
14. vesicular low density rock formed from trapped gases
15. 3.00 x 10^8 m/s
16. cooled lava blobs are ejected and solidify

1. type of volcano that forms from large amounts of magma erupt in a relatively short time period
2. the largest type of volcano
3. a measure of wave frequency equal to cycles per second
4. a volcano with steep slopes
6. glass like rock that cools very quickly
7. used to numerically grade volcanic activity and based on S and P wave activity
9. a volcano that has erupted at least once in recorded history
11. a path of volcanic activity that runs along the West Coast of the US and surrounds the Pacific Ocean
