Main channel where magma flows to the surface
a weak spot where molten material is heated up so hot that it forms a volcano
point where magma and gasses leave the volcano
molten mixture of rock, gasses, and water from the mantle
when lava flows over the sides of the volcano out of a vent
magma that reaches the surface
string of islands formed by volcanoes at convergent boundaries
occurs when an explosive eruption hurls out ash, cinders, bombs, and gasses
large hole at the top of a volcano formed when the roof of a magma chamber collapses
Pocket of magma; formed by subduction
layers of lava form high plateaus
weak spot in the crust where molten material, or magma, comes to the surface
forms when groundwater heated by magma, rises to the surface and collects in a pool
bowl shaped area that fills up with magma at the top of a volcano
a clean, reliable energy source caused when water is heated by magma
material formed from oxygen and silicone
fast moving, hot lava
opening in the side of a volcano; lava escapes through these vents
slow moving, cooled lava
A fountain of water and steam that builds up pressure underground and erupts at
regular intervals
Directions: Write the type of volcanic mountain is described by each statement (composite, shield, or cinder cone)
___________________________ 1. Volcanoes on the Hawaiian Islands are this type of volcano

___________________________7. Has a gentle slope and is flat and pancake-like
___________________________8. Has only thin runny lava
___________________________9. Has only thick of lava
___________________________10. This type is made of alternating layers of lava and ash
Directions: Answer the questions below. You do not need to use complete sentences.
1. What is the Ring of Fire?
2. Where are Hot spot volcanoes usually found?
3. How does the silica content affect magma?
4. What forms when magma heats water underground?
5. Mt. Fuji and Mt. St. Helens are what type of volcanic mountain?
6. True or False: Quiet and explosive volcanoes can cause damage far from the crater’s rim.
7. Is Yellowstone volcano located on a plate boundary?
8. Do all of the Hawaiian Islands have active volcanoes on them? Explain.
9. Japan and the Philippines are two examples of what?
10. List and describe the three stages of a volcano.
Directions: Fill in the blanks below with the best fit answer.
Volcanic island arcs are created when two ______________________________ plates converge at a plate boundary. The more
dense plate is ___________________________________ below the less dense plate. As the more dense plate sinks into the mantle,
its edge heats up turning into magma. The magma is _____________________ dense than the surrounding material, so it rises. As
the magma rises, it seeps through the cracks in the other plate, eventually reaching the ocean floor and creating
______________________________. Over time more eruptions add height to these “mountains”. If they rise above sea level, they
will become _________________________________. Many of these occur at these convergent plate boundaries to create volcanic
island arcs.
Directions: Label the following parts of a volcano.
