Volcano Parts
Magma/Lava
Volcanic Landforms
Other Stuff
100
This volcano has gently sloping sides.
A shield volcano
100
This is the point where the magma leaves the volcano's pipe.
the vent
100
This is molten rock above ground.
lava
100
Cloud coming from a volcano that contains ash and gas.
Eruption cloud
100
This is a volcano that is unlikely to erupt soon.
a dormant volcano
200
This type of volcano has layers of ash and lava.
A composite volcano
200
This is the narrow tube that rises from the magma chamber to the vent.
Feeder tube
200
This is molten rock below ground?
magma
200
This is when magma squeezes between relatively horizontal layers of rock.
a sill
200
This is when magma heats water underground and it is trapped.
a geyser
300
This type of volcano is a very steep cone shaped hill or mountain.
cinder cone volcano
300
This is the large area underground where the magma is held.
the magma chamber
300
This material changes the thickness of lava.
silica
300
This is when magma forces itself into a vertical crack and hardens.
a dike
300
This is one benefit of volcanoes for life.
fertile soil
400
This type of volcano has erupted in the past and may erupt again, but is not now erupting
Dormant volcano
400
This is the bowl shaped area that forms around the volcano's vent.
the crater
400
This lava has low viscosity and flows downhill quickly
basalt lava
400
The most volcanically active belt on Earth is called?
The ring of fire
400
These two other planets have extinct volcanoes similar to earth.
Venus and Mars
500
This is a hole left by the collapse of a volcanic mountain.
a caldera
500
This is a crack that lava flows out which is not the main vent.
the side vent
500
Rock fragments blasted out of an exploding volcano.
Pyroclastics
500
Lava is too viscous to flow and piles up around the vent creating this type of volcano.
a dome volcano
500
These volcanoes have not erupted for a very long time.
Extinct volcanoes
