This
information
is
designed
to
belie
the
misconception
that
the
capacity
of
air
to
hold
water
vapor
is
temperature
dependent
and
that
air
can
become
saturated
with
water
vapor.
The
temperature
of
a
cloud
droplet
or
ice
crystal
will
be
nearly
the
same
as
that
of
the
air,
so
people
imagine
that
somehow
the
air
was
to
blame.
But,
if
the
other
gases
of
the
air
were
removed,
leaving
everything
else

The
New
Millennium
Observatory
(NeMO)
is
a
seafloor
observatory
off
the
coast
of
Oregon,
which
studies
the
relationships
between
submarine
volcanic
events
and
the
chemistry
and
distribution
of
hydrothermal
vents
and
the
biologic
communities
that
depend
on
them.
The
research
activities
at
NeMO
provide
an
extraordinary
educational

The information on this site indicates that the life cycle of a glacier is more eventful than it appears. The site allows students to follow the journey of a single snowflake as it takes a ride through a glacier, a process that can take as much as 30,000 years to complete. It can be viewed as an interactive slide show or a single page of text and illustrations.

This
resource
gives
an
impression
of
how
immense
our
Universe
is
by
starting
with
an
image
of
the
Earth
and
then
zooming
out
to
the
furthest
visible
reaches
of
the
Universe.
Its
goal
is
to
show
astronomical
distances
without
scientific
notation.
Instead,
it
focuses
on
the
large
number
of
zeros
that
are
in
astronomical
distances
when
we
measure
them
with
a
familiar
unit
like
the
kilometer.
The
