Volcanoes/Science

2. main volcano vent
4. a thin lava flow that has a shiny, ropy appearance when hardened
6. molten rock beneath the earths surface
9. a mud flow developed when ash and water mix and run down the volcano
11. volcanoes that are showing signs of life such as earthquakes, steam, and possibly lava emissions
12. Processes by which magma wells up between oceanic plates due to divergence magma well up between and can form volcanoes
13. the extremely large crater or depression at the top of the top of some volcanoes after a huge explosion
15. a volcano that has physical evidence of its but no written record of its eruption
17. ash, cinders, blocks, bombs (smallest to largest in size)
18. Intrusive igneous rock bodies, including batholiths, stocks,sills, and dikes
19. type of volcano developers mainly from lava flows

1. loose ash and dust from a volcanic eruption that covers the ground in layers
3. a volcano that has not shown signs of volcanic activity for at least 50 years
5. a depositional mountain formed by magma rising to the surface at fault activity.
7. lava flow that has a rocky, jagged appearance when hardened
8. A pool formed by groundwater that has risen to the surface after being heated by a nearby body of magma
9. magma that flows onto the earths surface
10. vents in the ground where steam and other gases from volcanic activity escape
14. ejects hot water and steam high into the air in intervals
16. broken lava pieces that fall down the form of an a'a'flow
