Volcanic Landforms
Other Stuff
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 what forms when magma hardens in a volcanic pipe.

volcanic neck/ throat

100

Are hardened pieces of lava in a mouintain with steep sides since they result from explosive eruptions.

Cinders

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 between relatively horizontal layers of rock.
What is a sill?
200

Volcanoes erupt when magma (molten rock) from deep within the Earth rises to the surface due to buoyancy and the pressure of dissolved gases. This pressure builds up in underground magma chambers, forcing the magma through weak spots in the Earth's crust. 

Why do you think a volcano erupts?

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 type of eruption happens when there is no opening at the center of a mountain.

Fissure eruption

300

A type o fvolcano that erupts either continuously or periodically.

active volcano

400

A type of volcano that is formed from non explosive eruption?

Shield volcano

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.

Low Viscocity

400

Does not have enough pressure to erupt explosively.

Lava domes

400

The Agency in charge ofmonitoring volcanic activities.

PHILVOCS Philippine Institue of Volcanology and Seismology 

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

 a pipe through which magma rises;

conduit

500

This is cooler and slower moving lava.

High Viscocity

500

Are formed from low viscosity lava.

Lava plateaus

500
This is and explosion of ash cinders and bombs from a violent volcanic eruption.
What is a pyroclastic flow?
