Latin America Physical Geography 8.1
Physical Geography 8 mil sq. miles (~equal to N.A.) • Made up of Middle America and South America • Caribbean sometimes debated as part of MA
Yellow- Caribbean Green- Central America Red- Middle America Purple- South America All together is LATIN AMERICA
Physical Geography • Caribbean aka West Indies • 3 parts: Lesser Antilles, Greater Antilles, & Bahamas • Brazil is largest and most pop. of SA’s 13 countries
Highlands • Begins in Pac. Ranges/ Rockies Mexico’s Sierra Madre CA’s Central Highlands SA’s Andes • map pg 195 • Crust collision, sits on Ring of Fire
Highlands • Mexico’s Sierra Madre • Sierra Madre Oriental (eastern) & Sierra Madre Occidental (western) meet at Sierra Madre del Sur • Surrounds Mxn Plateau • Mild climate, volcanic soil in South= settlement
Highlands • Most Caribbean islands part of Central Highlands (range goes across sea) • Volcanic islands • Some still active
Highlands • Andes Mtns • 4500 miles long, world’s longest • Cordilleras- several 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 • Llanos (Colombia & Venezuela) & Pampas (Argentina & Uruguay) • Grazing plains, pampas= breadbasket • Cowboys= llaneros or gauchos
WATER • MA’s rivers are small, but SA’s are HUGE! • Rio Grande (Rio Bravo del Norte) is major one, though, outside SA • Amazon- 4000 miles (NYC to Rome, 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 (Rio de la Plata) before Atlantic
Notice the intense terracing!! • Lake Titicaca- world’s highest (elev.) navigable lake (Andes- Peru & Bolivia) • 12,500 ft above sea level • Center for Incas
WATER • Lake Titicaca is fed by rivers, melting glaciers, & rainfall • Losing water with shorter rain seasons & less glaciers (lowest since 1949)
Caribbean Sea • Lake Maracaibo- SA’s largest (Venezuela) • Caribbean inlet • Rich oil fields
Lake Nicaragua- CA’s largest lake (b/w Nicaragua & Costa Rica) • Smaller than Titicaca • Has small volcanic islands w/in • Known for Caribbean pirates!
Resources • Oil: Gulf of MX and southern Caribbean MX and Venezuela are leaders in world (OPEC) • Leaders in gold, silver, emeralds, copper (ancient civs. prospered with them) • Problems: geography, lack of $, social/political unrest prevent development of resources
