Clouds of hot ash
and chunks of
molten rock,
shooting out of a
vent at high speed.
Characterized by
calm rivers of redhot lava.
A hole in the
Earth’s crust
through which
magma rises to the
surface.
The area deep
beneath the Earth’s
surface where
magma collects.
During the 1980
eruption of this
2
volcano, 600 km of
forest was flattened
and scorched.
The area surrounding
the Pacific Plate
which contains almost
75% of the world’s
active volcanoes.
The newest
Hawaiian island,
still covered by
water.
The location of
Mount Rainier.
Where volcanoes are
most likely to form.
Places within
tectonic plates that
are directly over
columns of rising
magma.
These explosions
usually pose a
greater threat to
property than to
human life.
This can smother
crops, causing food
shortages and loss
of livestock.
Many of these may
occur as magma
shifts and rises
within a volcano.
This can cause
sunlight to be
blocked, resulting
in a drop in global
temperatures.
This volcanic
mud is created
when hot
volcanic ash
mixes with water.
This type of volcano
is made of only
pyroclastic material.
This type of
volcano has
alternating layers
of lava and tephra.
This type of
volcano has
gently sloped sides
and a wide base.
These landforms
are created when
empty magma
chambers collapse.
These are created
when lava flows over
a large area of land
after it escapes from
a crack in the
Earth’s crust.
This type of lava
is runny and
hardens with
wrinkles that
look like rope.
This element causes
magma to thicken,
and sometimes block
a volcano’s vent.
Magma will liquify
when this
decreases.
This lowers the
melting temperature
of rock.
This causes hot
magma rises to the
surface of the
Earth.
Make your wager
Hawaii’s Mauna Kea,
the tallest mountain
on Earth, is an
example of this.
