Section 1
What are the three types of
volcanoes?
Shield Volcanoes
• These volcanoes are
low and flat and have
flowing eruptions. As
the lava builds up on
the volcano it
becomes larger.
• Shield volcano
Composite Volcanoes
• These volcanoes
have tall mountain
like structures. Mount
St. Helens was a
famous composite
volcano. A crater at
the top is where the
lava flows out.
• Composite volcano
Cinder Cone Volcanoes
• These volcanoes are
the simplest kind of
volcanoes. They have
a bowl-shaped crater
where lava comes
out.
• When lava flows over
the top it creating the
rocks called cinders.
• Cinder cone volcano
Section 2
Why do volcanoes occur?
Occurring volcanoes
• Volcanoes occur when the Earths plates
pull apart causing magma to rise to the
surface. This is called plate tectonics.
What is plate tectonics?
Plate Tectonics
• Plate tectonics is the study of the motion
of the plates in the Earths crust. The
Earths tectonic plates are in constant
motion.
Section 3
Where do most volcanoes
occur?
• They form around the
Pacific Ring of Fire.
• There are many
volcanoes in Hawaii
also.
• Pacific Ring of Fire
How did the Pacific Ring of
Fire get its name?
Pacific Ring of Fire
• The ring of fire is roughly shaped like a
ring. It marks the area of the greatest
seismic activity in the world.
• Tons of volcanoes occur here everyday.
How do volcanoes form?
ERUPTION!!!
• A volcano is formed
when magma comes
up from the Earth and
through the cracks in
its surface.
• A volcanoes magma
makes up the Earths
surface.
• A volcano is really
cooled lava.
• A volcano erupting
What is a hot spot?
Hot Spot
• A hot spot is a flow of
magma that pushes
through areas of
weakness on the
Earths crust.

What is a volcano hazard?
Volcano Hazards
• Danger from a
volcanoes destruction
is called a volcano
hazard.
• In the past 500 years
200,000 people have
lost their lives due to
volcanoes.
• Destroyed homes
What hazards can volcanoes
produce that effect people?
Destruction
• The accumulation of
ash can affect
peoples lungs.
• The ash is so small
that it can easily get
in your lungs.
The ash
How do you get prepared for a
volcano?
Pack a first aid kit.
• For the first aid kit you
should provide the
following:
• Flashlight
• Extra batteries
• Extra food and water
• Medicines
• Dust mask
Section 5
What is our favorite volcano in
history?
Mount St. Helens
• During the past 4,000
years, Mount St.
Helens has erupted
more frequently than
any other volcano in
the Cascade Range.
• Most of Mount St.
Helens is younger
than 3,000 years old.
Mount St. Helens
• The first sign of
activity at Mount St.
Helens in the spring
of 1980 was a series
of small earthquakes
that began on March
16.
Section 6
What is our favorite presently
active volcano?
Mount Aso
• Mount Aso is one of
the largest volcanoes
from those seen all
over the world
• This active volcano is
located in Japan on
an island called
Kyushu.
• Mt. Aso’s crater
How do people live by Mount
Aso?
People’s lives
• There are many big
cities close to active
volcanoes.
• People don’t seem to
mind it that they could
be apart of a huge
disaster at any time.
