What is a chemical property?
B 400
Pahoehoe and aa are
produced during __________
eruptions.
B 500
What are quiet?
B 500
A(n) ________________
happens when an explosive
eruption hurls ash, cinders,
bombs, and gases out of a
volcano.
C 100
What is a pyroclastic flow?
C 100
Liquid magma flows upward
through the crust because it is
_________ dense than the
solid material around it.
C 200

A volcano that is erupting or
has shown signs that it may
erupt in the future is called

C 500
What is active?
C 500
A(n) ___________ is a wide,
gently sloping mountain
made of hardened layers of
low-silica lava.
D 100
What is a shield volcano?
D 100
A(n) _______________
forms when magma hardens
in a volcano’s pipe and is
later exposed.
D 200
What is a volcanic neck?
D 200
Magma that forces itself
across rock layers hardens to
form this.
D 300
What is a dike?
D 300
A(n) _______________ is hot
water and steam that erupts
from the ground.
D 400
What is a geyser?
D 400
When the top of a volcanic
mountain collapses, a
____________ forms.
D 500
What is a caldera?
D 500
This is the energy derived
from water that has been
heated by magma
underground.
E 100
What is geothermal energy?
E 100
This is why explosive
eruptions cause ash, cinders
and bombs to be produced.
E 200
What is the lava that is
ejected has a high viscosity
and silica content which
forces it to be broken down as
it cools to form these
particles?
(Accept reasonable answers)
E 200
This is how geothermal
energy is used.
E 300
What is for heating homes as
hot water and for creating
electricity by using steam to
power turbines?

E 300
This is the main difference
between a composite volcano
and the type of volcano that
forms the Hawaiian Islands.
E 400
What is the Hawaiian Islands
are shield volcanoes made up
of thin layers of lava in a

the rock and opened others or
may have widened or
narrowed some channels?
