100
This volcano has gently sloping sides.
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 a volcano that is unlikely to erupt again.

What is a extinct volcano?

100

This is groundwater that is heated by magma that collects in a natural pool on Earth’s surface.

What is a hot spot?

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 a volcano that is “sleeping” or can possibly erupt in distant future.

What is a dormant volcano?

200

This is when magma heats water underground and it is sprayed in the air.

What is a geyser?

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 a volcano that is erupting or shows signs of erupting in near future

What is an active volcano?

300

This is and explosion of ash cinders and bombs from a violent volcanic eruption.

What is a pyroclastic flow?

400
This is a high level area formed by rising underground lava.
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 trapped in magma and under a lot of pressure.

What are gases?

400

These are the dangers of a dormant volcano.

What is that when they erupt it is unpredictable?

400

This how magma with a high amount of silica flows.

What is thick and sticky?

500
This is a hole left by the collapse of a volcanic mountain.
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

Thin runny lava is a result of this.

What is a quiet eruption?

500

These are the main differences between the three stages of activity.

What is

  • Active - volcano is erupting or shows signs of erupting in near future
  • Dormant - volcano is “sleeping” or can possibly erupt in distance future
  • Extinct - volcano is dead or is unlikely to erupt again
500

This is a type of volcano has many layers of thin runny lava that build up a high level area.
