What Type of Volcano?
A
•Cinder Cone
•What are cinder
cones made of?
A
•Loose bubbly light
weight chunks of
rocks
•Rubble
•Why are cinder
cones not steeper?
A
•Cinder Cones have
moderately sloping
sides because loose
rubble doesn’t stack
well.
What Type of Volcano?
A
Shield
•Why are shield
volcanoes not
steeper?
A
• The lava shield
volcanoes are made of
is very thin and travels
long distances before it
hardens.
•Why are Shield
Volcanoes generally
good neighbors?
A
• They don’t explode
• Their lava moves
slowly enough to be
avoided
•Why don’t shield
volcanoes explode?
A
•They are made of
solid basalt which
is VERY strong
What Type of Volcano?
Composite A
•Why are composite
volcanoes named
composite?
They are composed of
many different types of
layers
A
•What is the
tallest type of
mountain on
Earth?
A
• A shield Volcano
named Mona Loa in the
Hawaiian Islands.
•Which type of
volcano is most
likely to blow up?
A
•Composite
•Why do Composite
volcanoes tend to
blow up?
A
• They are very weak
because many of their
layers are nothing but ash
or cinder. When too much
pressure builds up, they
blow their layers apart.
•Which type of
volcano makes a lot
of noise and
fireworks, but isn’t
too likely to
explode?
A
•Cinder Cone
•Where can we find
cinder cones in the
United States?
A
•Arizona and
New Mexico
What Type of Volcano?
•What caused the
Hawaiian Islands
to form?
A
•Hot spots
in the
mantle
•Why are there so
many Hawaiian
islands from 1
hot spot?
A
• The Earth’s crust is
moving, but the hot
spot is not.
Consequently, new
volcanoes form over
the hot spot after the
old ones move away.
•What type of volcano
is found at
Yellowstone?
A
•A Supervolcano
•Why did they have a
hard time locating
the Yellowstone
Volcano?
A
•It is so big that you
have to be in
space to see the
whole caldera.
•Where in the United
States can we find a
LOT of shield
volcanoes?
A
•Hawaii
•Why are Cinder
cones unlikely to
explode?
A
•The cinder rocks are
loose, so the new
lava can just push
the old lava out of
the way.
•Where can we find
some composite
volcanoes in the
USA?
A
• Along the Pacific coast
in Washington and
Oregon.
•What caused these
coastal volcanoes to
form?
A
• The Cascade range
was formed by a
subduction zone where
the oceanic plate is
sliding under the
continental plate.
•What sorts of
problems could
supervolcanoes
cause?
A
•
•
•
•
•
•
•
•
Loss of sunlight
Loss of summer
Extinctions (maybe of people)
Loss of crops and animals
Starvation
Economic collapse
Wars
Mass emigration to other countries
•Volcanoes with quiet
eruptions occur in
what 2 places?
• Divergent Boundaries
and
• Ocean Floor Hot Spots
•Volcanoes with
explosive
eruptions occur in
what 2 places?
• Convergent boundaries
with Subduction Zones,
and
• Contenental Hot Spots
• What rock are
explosive eruption
volcanoes made of?
•Andesite
• What rock are quiet
eruption volcanoes
made of?
•Basalt
