shield volcano
100
rate at which something flows
viscosity
100
intrusive igneous rock formations that form from large magma reserves that hardened underground
plutons
200
volcanoes that cause seafloor spreading
divergent volcanoes
200
tube that magma travels up to reach surface
conduit
200
steep sloped narrow volcanoes, tend to have explosive eruptions
cinder cones
200
the higher the _______ content, the more viscous the lava is, and the more gases get trapped inside. resulting in more explosive eruptions.
silica
200
large mountainous plutons
batholith
300
volcanoes that arnt formed on boundaries, the magma is so hot it melts through the crust.
hot spot volcano
300
opening magma exits out of
vent
300
largest, mountainous volcanoes, tend to have multiple vents along sides of the mountain
composite volcano
300
consistency of lava depends on temperature and______________
pressure
300
narrow tall plutons that pushed against the crust
laccolith
400
hot spot volcanoes in the ocean make volcanic islands like hawaii. hot spot volcanoes on land, called _______ _________ , make big plateus.
flood basalts
400
bowl shaped depression at the top of the volcano
crater
400
molten rock above ground
lava
400
erupted material when a volcano explodes, can be solidified lava, ash, or even boulders.
tephra
400
long horizontal plutons that flattened against the crust
sill
500
crack in ground that lava can leak through
fissure
500
large cratered volcanoes that form when a volcano collapses in on itself
caldera
500
molten rock below ground
magma
500
