What is magma called above the surface of the Earth?
Magma above the surface of the Earth is called lava.
100
What comes out of a cinder cone?
Dust, rock and ash come out of the cinder cone.
100
What comes out of a composite cone?
Alternating eruptions of dust, rock, ash and lava come out of composite eruptions.
100
What comes out of a shield cone during an eruption?
Lava oozes out of shield cones during eruptions.

What is viscosity?
What is a liquid's resistance to flow?
200
What is molten rock below the surface of the Earth called?
Molten rock below the surface of the Earth is called magma.
200
What does the base of a cinder cone look like?
The base of the cinder cone is narrow.
200
How does the base of the composite cone look?
The base of the composite cone is wide.
200
What does the base of the shield cone look like?
The base of the shield cone is wide.
200
How does the viscosity of lava effect the type of eruption?
Highly viscous lava makes explosive eruptions, while low viscosity lava makes quiet eruptions.
300
Other than lava, what might get erupted from a volcano?
Dust, rock and ash might also get erupted.
300
What does the slope of the cinder cone look like?
The slope are steep.

What does the slope of the composite cone look like?
The slope is steep.
300
What does the slope of the shield cone look like?
The slope of the shield cone is gentle.
300
How do volcanoes form along divergent plate boundaries?
As two plates divide, magma rises to form volcanoes.
400
Name three parts of a volcano...
There are many parts to a volcano, these include: the magma chamber, the vent, a side vent, crater, cone, lava flow, or ash cloud.

What type of eruption does a cinder cone have?
Cinder cones have explosive eruptions.
400
What type of eruption do composite cones have?
Composite cones have both quiet and explosive eruptions.
400
What type of eruption does a shield cone have?
Shield cones have quiet eruptions.
400
How do volcanoes form along convergent plate boundaries?
When one plate subducts below another, it melts, rises, and forms a volcano.
500
What is the tube that leads up to the crater of the volcano called?
The tube is called the vent.
500
Name two hazards or dangers associated with explosive eruptions.
Pyroclastic flows, volcanic bombs, and ash - dust and rock are all dangers associated with volcanic eruptions.

Compare an explosive and quiet eruption.
Explosive eruptions can be dangerous, while quiet eruptions are not as severe.
