provides
general
information
about
volcanoes.
It
illustrates
the
growth
of
a
volcano,
using
Paricutin
and
Mt.
St.
Helens
as
examples
of
an

volcano
and
a
lava
dome.
The
terms
extinct
and
dormant
are
also
discussed.
This
site
provides
an
explanation
of
why
and
how
volcanoes
form,
zones
of

This
activity
has
students
use
simple
sine
waves
to
explore
constructive
and
destructive
interference
in
seismic
waves.
After
plotting
the
summative
points
of
two
sine
waves,
students
connect
the
points
to
create
the
resulting
complex
wave.
Once
they
have
successfully
drawn
their
complex
wave,
they
will
answer
the
questions
listed
on
the
student
handout.
