Dust blowing from
Rio Grande
channelway,
Bolivia

Coastal Dunes,
Brazil
Interaction of wind,
water, and sand…
Small part of an active
dune field on Brazil’s
north coast. Dunes
are built by persistent
easterly winds off of
the equatorial Atlantic
and have interspersed
freshwater ponds.

Hurricane Claudette, along the Gulf Coast of Texas
(Category I, 7/15/03)
Solar energy drives wind and water currents on the
Earth’s surface, accounting for circulation patterns,
climate, and weather phenomena such as this cyclone.

LARGE-SCALE HUMAN-INDUCED
ENVIRONMENTAL IMPACTS
AND CHANGES
Photos show rapid modification of the Earth’s surface by humans.
41
1985
1992
TROPICAL RAIN FOREST DESTRUCTION
Southern Amazon River Basin, Rondônia, Brazil
Photos provide a visual indication of the rate of deforestation
occurring. The amount of clear-cut area now exceeds the area of
remaining rain forest timber stands.
42
2001
1983
Betsiboka River Delta, Bombetoka Bay,
Madagascar
Removal of native forest, massive soil
losses, rapid delta expansion
43
Etosha Pan,
dry salt lake,
Namibia
Angola
Namibia
Nation boundary
revealed because
of differing
grazing
practices.
Soil in Namibia
is much more
reflective
because of
de-vegetation due
to overgrazing.

1985
1992
Aral Sea, Kazakhstan and Uzbekistan (top to north)
(~46% water level decrease since 1960; level continues to fall)
Development of agricultural irrigation projects impedes recharge.
With reduced fresh water quantities and constant evaporation, the
sea has become more saline and shrunk drastically. It has also
become polluted with pesticides and fertilizers.
46
Aral Sea, bisected, 2002
(top to northeast)
47
Pivot irrigation,
Saudi Arabia, is
leading to
groundwater
depletion from
deep aquifers
and to further
desertification.
Water reserves
are finite.
Center pivot
irrigation systems
are ~0.6 mi (1 km) in
diameter.
48
Mono Lake, Sierra Nevada, CA
Water drawn to supply LA has
resulted in lowered lake levels,
increased salinity, and an
endangered ecosystem.
Las Vegas, NV
Rapid urbanization in a desert
setting stresses surface and
ground water resources.

Lake Powell and the Colorado River, Colorado Plateau, UT-AZ
“The building of Glen Canyon Dam ushered in the modern environmental
movement…” -- David Brower, Sierra Club
“The canyonlands did have a heart, a
living heart, and that heart was Glen
Canyon and the wild Colorado.”
-- Edward Abbey

Sunglint and smog layer over
Upstate New York (looking
southwest)
Air pollution layer is capped by
an atmospheric inversion, marked
by top cloud layer.
Po River Valley smog,
northern Italy (looking west)
The Alps provide a natural
barrier to smog migration, thus
trapping it in this heavily
industrialized area.

PHOTOS
FROM
SPACE:
1. Are excellent observational data to observe Earth’s dynamic
surface and its systems.
2. Document large-scale earth-system processes and interactions.
3. Show natural and human-induced, short-term environmental
changes and hazards.
4. Reveal the effects humans have on the Earth’s environment.
5. Are readily accessible and easily downloadable from various
NASA websites.
55
56
By using Space Shuttle and International Space Station
photographs in the classroom…
1. Increases our understanding of how remote sensing is used to
document, interpret, and monitor the surface of the Earth.
2. Incorporates a vast, impressive visual resource under-utilized in
geoscience education.
3. Provides a valuable, alternative electronic data set that enhances
student learning, especially in technology based activities.
