100
This is molten rock above ground.
What is lava?
100
What is one method scientists use to predict volcanic eruptions?
What is the study of earthquakes, gases, slope and temperature?
100
This is a volcano that is unlikely to erupt soon.
What is a dormant volcano?
200
This type of volcano has layers of pyroclastic material 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 or central vent?
200
This is molten rock below ground.
What is magma?
200
This is the volcanically active place on Earth's surface that are far from plate boundaries.
What is a hot spot?
200
Volcanoes are most likely to form at this place.
What is a plate boundary?
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.
What is silica?
300
This is the process when two plates collide, subduct and create magma.
What is a convergent boundary?
300
What is a benefit from volcanoes?
What is fertile soil, carbon dioxide releasing into the air, build new land.
400
One example that can cause a volcano to erupt explosively.
What is water? What is silica?
400
This is the bowl shaped area that forms around the volcano's vent.
What is the crater?
400
This is lava that flows slowly, like wax dripping from a candle.
What is pahoehoe lava?
400
This is a deep crack that forms when two plates are pulling away from eachother.
What is a rift zone?
400
What kind of volcano will never erupt again?
What is extinct volcano?
500
This is a hole left by the collapse of a magma chamber's roof.
What is a caldera?
500
This is a crack that lava flows out which is not the main vent.
What is the side vent or secondary vent?
500
This type of lava pours out quickly and forms a brittle crust.
What is Aa lava?
500
This is when two plates separate and causes magma to rise through the cracks.
What is a divergent boundary?
500
This is the spot where the most active volcanoes are located.
What is the Ring of Fire?
