Run fast, or I will consume you with my ash, gas and bombs.
What is a pyroclastic flow?
100
Caused by hot spots
What is a shield volcano?
100
Long tube which comes up from Earth's crust.
What is the pipe?
100
You may choose to visit me but be aware a sleeping giant often gets disturbed.
What is a dormant volcano?
100
Magma has formed me leaving behind hard rock exposed to erosion.
What is a volcanic neck?
200
I flow down the hillside of a volcano.
What is the lava flow?
200
Exploding and spewing ash, cinders and bombs.
What is a Cinder Cone Volcano?
200
Collection of magma.
What is the magma chamber?
200
Go ahead, set-up shop here, start farming, I am not going to bother with you anymore.
What is an extinct volcano?
200
Magma oozes through horizontal layers hardening to form these.
What is a sill?
300
When visiting the west coast be aware you are in this area.
What is the Ring of Fire?
300
Cinder Cone volcanoes are explosive due to a large amount of this ingredient.
What is high silica content?
300
Area in which gases and molten rock spill out.
What is the vent?
300
Being quite explosive, the magma gets trapped in the pipe, thus this builds up creating a tremendous amount of pressure.
What are dissolved gases?
300
I am most often found in the west. I am a mass of rock which is formed when a large body of magma cools inside the crust.
What is a batholith?
400
Volcanoes are classified in two main categories: one is like a mouse and another like a lion.
What are quiet and explosive volcanoes?
400
Mount St. Helens is a good example of this type of volcano, which has alternating eruptions with lava flows.
What is a composite volcano?
400
Bowl shaped area at top of volcano created by the vent.
What is a crater?
400
Don't get too close, or you might not be able to get those pictures developed.
What is an active volcano?
400
Magma that forces itself down through rock layers hardens into this.
What is a dike?
500
Volcanoes most often occur where two plates collide or pull apart, which is also know as these two technical terms.
What is converging and diverging plates?
500
Created through long cracks that are filled and cooled with lava flows.
What is lava plateau?
500
Collapse of the top of the volcano, sometimes fills with water and or another active volcano.
What is a caldera?
500
I am the smallest pieces spewed from volcanoes. I can cause havoc to air traffic patterns.
What is volcanic ash?
500
Formed when uplift pushes a large body of hardened magma towards the surface causing a bend upward.
What is a dome mountain?
