of Fire
Highlands
• Mexico’s Sierra Madre
–Sierra Madre Oriental
(eastern) & Sierra Madre
Occidental (western) meet at
Sierra Madre del Sur

of Central Highlands (range
goes across sea)
–Volcanic islands
–Some still active
Highlands
• Andes Mtns
–4500 miles long,
world’s longest
–Cordillerasseveral ranges
running parallel
–Encircle high
plains (altiplano) in
Peru & Bolivia
Atacama Desert
• Driest place on Earth!
– Some areas have never received rainfall since
recordkeeping began
• More than a million ppl live here
– Live near coast, oases, or farm with drip-irrigation
• Fog Catching Net:
– Fog rolls in condenses
on net drips to pipes
water crops
Highlands
• Mato Grosso Plateau- from
eastern Peru & Bolivia to most
of Brazil
–Low pop.
• Brazilian Highlands- from MGP
to eastern Brazil, ends in
escarpment (cliff)
Lowlands
• Coastal plains along Brazil’s coast
–Next to escarpment
–Prime area for settlement/tourism

Italy)
– 20% of Earth’s freshwater, 10X the volume
of the Mississippi
– Hundreds of sm. rivers join it Amazon
Basin (creates a valuable functional region)
 40% of SA
– Only navigable for 2300 miles from Atlantic
WATER
• Parana, Paraguay, &
Uruguay next lrgst
water system
–Commercial
highway,
hydroelectricity
–Flow into estuary
