A volcano is:a mountain made by magma and lava forced upthrough the Earth’s crust.
Five types of volcanoesThe types of volcanoes depend on two main factors:                    Viscosity                    ...
StratovolcanoHigh viscosity (think magma)High gas contentSteep hills; high mountainsThe most powerful volcanoes!!!Examples...
Cinder ConeMedium viscosityHigh gas contentMost have a bowl shaped crater at the topExample:                              ...
ShieldLow viscosityLow gas contentUsually low and can be hundreds of  miles wideExample:Maunu Lau in Hawaii
DomeHigh viscosityLow gas contentOften found in the crater of StratovolcanoesExample:Dome on Mt. Saint Helens
CalderaFormed by the collapse of land after  a volcano eruptsShaped like a cooking pot or caldronExample:La Cumbre in the ...
I like volcanoes because they explode fiery red                    lava!!!!!          http://www.youtube.com/watch?v=4aYQi...

  1. 1. BySarah Wright
  2. 2. A volcano is:a mountain made by magma and lava forced upthrough the Earth’s crust.
  3. 3. Five types of volcanoesThe types of volcanoes depend on two main factors: Viscosity + GasThe higher the viscosity and the higher the gas content the more powerful thevolcano.The five type of volcanoes are:1. Stratovolcano2. Cinder Cone3. Shield4. Dome5. Caldera
  4. 4. StratovolcanoHigh viscosity (think magma)High gas contentSteep hills; high mountainsThe most powerful volcanoes!!!Examples: Vesuvius Naples, ItalyVesuzius in ItalyMt. Saint Helen’s in US Mt. Saint Helens Montana, USA
  5. 5. Cinder ConeMedium viscosityHigh gas contentMost have a bowl shaped crater at the topExample: ParicutinStromboli in Italy MexicoParicutin in Mexico Stromboli, Italy
  6. 6. ShieldLow viscosityLow gas contentUsually low and can be hundreds of miles wideExample:Maunu Lau in Hawaii
  7. 7. DomeHigh viscosityLow gas contentOften found in the crater of StratovolcanoesExample:Dome on Mt. Saint Helens
  8. 8. CalderaFormed by the collapse of land after a volcano eruptsShaped like a cooking pot or caldronExample:La Cumbre in the Galapagos Islands
  9. 9. I like volcanoes because they explode fiery red lava!!!!! http://www.youtube.com/watch?v=4aYQixhd WY4
