consists
of
a
series
of

Major
volcanic
eruptions
alter
the
Earth's
radiative
balance,
as
volcanic
ash
and
gas
clouds
absorb
terrestrial
radiation
and
scatter
a
significant
amount
of
the
incoming
solar
radiation,
an
effect
known
as
"radiative
forcing"
that
can
last
from
two
to
three
years
following
a
volcanic
eruption.
This
results
in
reduced
temperatures
in
the
troposphere,
and
changes
in
atmospheric
circulation
patterns.

Volcanic
eruptions
are
thought
to
be
responsible
for
the
global
cooling
that
has
been
observed
for
a
few
years
after
a
major
eruption.
The
amount
and
global
extent
of
the
cooling
depend
on
the
force
of
the
eruption
and,
possibly,
its
latitude.
When
large
masses
of
gases
from
the
eruption
reach
the
stratosphere,
they
can
produce
a
large,
widespread
cooling
effect.
As
a
prime
example,
the
effects
of

This
lesson
will
help
to
acquaint
students
with
the
characteristics
and
effects
of
volcanic
activity.
In
addition
to
Internet
research,
students
will
conduct
experiments
on
fluid
viscosity
as
it
relates
to
lava
and
the
volume
of
ejecta
produced
by
a
volcano.
They
will
explore
how
plate
tectonics
relates
to
volcanoes,
and
how
volcanoes
are
formed.
They
will
be
able
to
list
the
parts
and
several
characteristics

In
this
module,
students
can
explore
two
ways
that
volcanoes
affect
Earth:
by
directly
threatening
people
and
the
environments
adjacent
to
them,
and
by
ejecting
aerosols
into
the
atmosphere.
The
module
consists
of
three
investigations
in
which
they
will
study
the
local
effects
of
volcanism
using
images
of
Mount
St.
Helens,
examine
how
the
effects
of
volcanic
activity
can
be
remotely
sensed
and
monitored
