What is a shield volcano?
100
This is the point where the magma leaves the volcano's pipe.
What is the vent?
100
This is molten rock above ground.
What is lava?
100
This is what forms when magma hardens in a volcanic pipe and the surrounding mountain erodes away.
What is a volcanic neck?
100
This is a volcano that has erupted within the past 10,000 years and is unlikely to erupt soon but may.
What is a dormant volcano?
200
This type of volcano has layers of ash and lava.
What is a composite volcano?
200
This is the narrow tube that rises from the magma chamber to the vent.
What is the pipe.
200
This is molten rock below ground?
What is magma
200
This is when magma squeezes sideways between relatively horizontal layers of rock.
What is a sill?
200
These landforms form when 2 oceanic plates converge and one is subducted beneath another.
What is an island arc?
300
This type of volcano is a very steep cone shaped hill or mountain.
What is a cinder cone volcano?
300
This is the large area underground where the magma is held.
What is the magma chamber?
300
This material changes the thickness of lava. (relate it to flour)
What is silica?
300
This is when magma forces itself into a vertical crack and hardens.
What is a dike?
300
This is one benefit of volcanoes for people
What is fertile soil?
400
This is a high level area formed by a thin runny lava that travels far before cooling.
What is a lava plateau?
400
This is the bowl shaped area that forms around the volcano's vent.
What is the crater?
400
This is fast moving hot lava that looks like dripping wax from quiet volcanoes.
What is pahoehoe?
400
This is a mass of rock that forms when a large body of magma cools inside the crust.
What is a batholith?
400
This is when volcanic ash mixes with melted snow or ice.
What is a lahar?
500
This is a hole left by the collapse of a magma chamber.
What is a caldera?
500
This is a crack that lava flows out which is not the main vent.
What is the side vent.
500
This provides the force that causes magma to erupt to the surface?
What are dissolved gasses trapped in magma?
500
These are smaller bodies of magma that form a feature by forcing layers of rock to bend upward.
What is a dome mountain?
500
This is the type of flow that produces of ash cinders and bombs from a violent volcanic eruption.
What is a pyroclastic flow?
