the
potential
of
combining
observed
river
discharge
information
with
a
climate-driven
Water

Model
in
order
to
develop
composite
runoff
fields
that
are
consistent
with
observed

This
combination
preserves
the
accuracy
of
discharge
measurements
as

Discovering
Plate
Boundaries
is
based
on
5
world
maps
containing
earthquake,
volcano,
topography,
satellite
gravity,
and
seafloor
age
data.
The
novel
aspect
of
the
exercise
is
the
"jigsaw"
manner
in
which
student
groups
access
the
maps
and
use
them
to
discover,
classify,
and
describe
plate
boundary
types.
The
exercise
is
based
only
on
observation
and
description,
which
makes
it
useful
at
a

These population clocks from the U.S. Census Bureau show population estimates for the United States and world. Estimates are projected to the current date and time; there are also component settings for U. S. population (one birth every X seconds, one death every X seconds), and monthly population figures for the world.

The
Drought
Monitor
provides
a
weekly
overview
of
where
in

United
States
drought
is
emerging,

Responding
to
the
need
for
accurate,
centralized
drought
information,
a
resource
that
summarizes
information
from
numerous
drought
indices
and
indicators
has
been
created
on
a
single,
easy-to-read
color
