This
site
presents
a
brief
definition
of
scaffolding
and
example
of
its
usefulness
in
media
education.
Published
by
the
Media
Awareness
Network,
the
summary
was
adapted
from
a
posting
to
their
listserv
by
educator
Bakari
Chavanu.
He
defines
scaffolding
as
developing
a
unit
of
study
through
a
set
sequence
of
four
steps,
which
are
listed.
He
also
provides
an
example
of
how
the
steps
of
scaffolding

This USGS fact sheet summarizes the occurrence of Balkan Endemic Nephropathy, a serious kidney disease that occurs only in tributary valleys of the Danube River in Romania, Bulgaria, and the former Yugoslavia. There is a close correspondence between the location of affected villages and the occurrence of local coal deposits.

Mass
Wasting
is
a
course
handout
designed
to
initiate
discussion
on
the
factors
involved
in
mass
wasting
(eg.
creep,
solifluction,
falls,
slides,
and
flows)
and
the
methods
used
to
prevent
mass
wasting.
Definitions
are
given
for
key
terms
such
as
angle
of
repose
and
lahars.
Photographs
illustrate
the
effects
of
rockslides
and
slumps.

Sedimentary
Rocks:
Carbonate
Rocks
is
a
course
handout
meant
to
accompany
the
discussion
of
chemical
and
biochemical
sedimentary
rocks.
Rock
composition
is
broken
into
the
main
categories
of
limestone
and
dolostone.
Depositional
conditions
are
discussed,
including
the
topics
of
coral
reefs,
plankton,
and
carbonate
compensation
depth
(CCD).
There
are
a
few
photographs,
which
display
calcareous
algae.

This
is
a
course
handout
to
accompany
the
discussion
of
sedimentary

environments.
Facies
are
defined
as
all
of
the
characteristics
of
a
particular
rock
unit.
The
effects
of
transgressions
and
regressions
on
depositional
environments
are
discussed
with
reference
to
fluctuations
in
sea
level.
These
effects
are
then
related
to
Walther's
Law.

of
the
rock
cycle;
explain
and
give
examples
of
the
various
sedimentary

The
purpose
of
the
handout
is
to
identify
the
three
major
types
of
soils:
pedalfer,
pedocal,
and
laterite,
and
to
understand
the
soil
profile.
This
is
accomplished
with
brief
descriptions
of
the
soil
horizons
and
the
designation
of
common
elements
to
pedalfers,
pedocals,
and
laterite
soils.
The
handout
is
concluded
with
a
discussion
of
soil
erosion.

that
appears
in
the
book
'Cartographies

by
Mark

the
purpose
of
allowing
Monmonier
to
state
what
he

are
the
ten
most
risky
places
to
inhabit
in
the
United
States,
most
of
which
are
susceptible
to
natural
hazards.
Among
those
he
lists
are
California,
coastal
Alaska
and
Hawaii,
