6 different types of volcanoes - correct answer-Fissure, Shield, Ash-cinder, composite,
Dome, Caldera
Example of a fissure volcano - correct answer-East Rift Zone, Kileauea Volacno, Hawaii
volcanoes national park
Example of a shield volcano - correct answer-Mount vulcan
Example of a ash cinder volcano - correct answer-Lava Butte
Example of a composite volcano - correct answer-Popocatepetl, an active composite volcano
in Mexico
Example of a Dome volcano - correct answer-Mount Myoko, lava dome
Example of a caldera volcano - correct answer-caldera at Kaguyak volcano in Alaska about
1.5 miles across
chracteristics of fissure volcanoes - correct answer-very liquid lava emitted from fractures
and very wide flowing
chracteristics of shield volcanoes - correct answer-liquid lava emitted from a large central
vent
chractersitics of ash cinder volcanoes - correct answer-explosive liquid lava from a small
central vent. May over time develop into a shield volcano
Chracteristics of composite volcanoes - correct answer-more viscous lava more expolosive
eruptions developing pyroclastic flows largely
charatceirsitcs of dome volcanoes - correct answer-very viscous lava small but can be
explosive commonly occurring next to composite volcanoes
characteristics of caldera/super- volcanoes - correct answer-a very large composite volcano
which has collapsed after a very explosive event
3 different types of magma associated with volcanic eruptions - correct answer-balsaltic
magma, andesitic magma, rhyolitic magma
Basaltic magma - correct answer-magma silica content 45-50%, temp. 1,000-1,200 degrees,
low gas levels that are easily released with little build up, Almost continuous e.g. Hawaii
