| Question | Answer |
|---|---|
| the resistance of a liquid to flowing | viscocity |
| groundwater that is heated by magma, rises to the surface and collects in a pool | hot spring |
| a massive rock that is formed when a large body of magma cools in the crust | batholith |
| any characteristic of a substance that can be observed,measured without changing the composition | physical property |
| this happens when an explosive eruption hurls out hot gases,ash,cinders and bombs | pyroclastic flow |
| a string of islands made by volcanoes along a deep ocean trench | island arc |
| any property that can produce a change in the composition of matter | chemical property |
| a volcanic eruption that has lava low in silica,flows slowly,forms flat layers,and makes a shield volcano | quiet eruption |
| a huge hole left when a volcanic mountain collapses | caldera |
| magma that reaches the earth's surface | lava |
| a molten mixture of rock forming substances,gases, and water from the mantle | magma |
| a volcanic eruption that has lava high in silica,hurls out pyroclastic flow | explosive eruption |
| a belt of volcanoes that rim the Pacific Ocean | Ring of Fire |
| an area where material from deep in the mantle rises and melts the crust and forms magma | hot spot |
| a break in the earth's crust where magma rises to the surface | volcano |
| Why are volcanic soils so fertile? | they have potassium and phosphorus in it |
| what is geothermal energy | energy made by water that is heated by magma |
| how is geothermal energy used | for hot water and electricity |
| what type of volcanoes are the Hawaiian Islands and how are they formed | shield volcanoes; formed from a hot spot made from thin layers of lava |
| why are ash cinders and bombs produced from explosive eruptions but not in quiet eruptions | explosive eruptions break lava into ash, cinders, and bombs while quiet eruptions flow slowly out |
