a. Main channel where magma flows to the surface
b. a weak spot where molten material is heated up so hot that it forms a
volcano
c. point where magma and gasses leave the volcano
d. molten mixture of rock, gasses, and water from the mantle
e. when lava flows over the sides of the volcano out of a vent
f. magma that reaches the surface
g. string of islands formed by volcanoes at convergent boundaries
h. occurs when an explosive eruption hurls out ash, cinders, bombs, and gasses
i. large hole at the top of a volcano formed when the roof of a magma chamber
collapses
j. Pocket of magma; formed by subduction
k. layers of lava form high plateaus
l. weak spot in the crust where molten material, or magma, comes to the
surface; most occur at divergent plate boundaries
m. forms when groundwater heated by magma, rises to the surface and collects
in a natural pool
n. bowl shaped area that fills up with magma at the top of a volcano
o. a clean, reliable energy source caused when water is heated by magma
p. material formed from oxygen and silicone; most abundant materials in Earth’s
mantle and crust
q. fast moving, hot lava
r. opening in the side of a volcano; lava escapes through these vents
s. major volcanic belt formed by many volcanoes at the rim of the Pacific Ocean
t. slow moving, cooled lava
u. A fountain of water and steam that builds up pressure underground and
erupts at regular intervals
Directions: Write the type of volcano is described by each statement (composite, shield, or cinder cone)

examples for each.
2. Where do most volcanoes occur?
10. How do geysers and hot springs form?
11. Compare and contrast a quiet and explosive
eruption.
3. Where is the Ring of Fire located? Why is it
located there?
12. What causes a volcano to erupt?
4. How are island arcs created?
13. List and describe the 3 stages of a volcano.
5. Give two examples of island arcs.
6. How do hot spot volcanoes form?
14. When underwater volcanoes break the surface
of the water, they are then called what?
7. Give two examples of hot spot volcanoes.
15. Label the following parts of a volcano: the pipe,
ash cloud, crust, lava flow, magma chamber,
vent, side vent, crater
8. Do all of the islands in the Hawaiian Islands
have active volcanoes on them? Explain.
9. How does silica content in the magma affect the
thickness of the lava?
