Latin America Introduction – Location – Physical Characteristics GCU 122 – World Regional Geography Jason Donoghue Chandler-Gilbert Community College Introduction • Lecture accompanied by these presentations will make up the bulk of this course. – Take good notes, and you will be successful. • Each presentation will tackle a different aspect of the region we are covering, but will be presented in the same format. Location – Latin America • Latin America includes all of the countries south of the United States from Mexico all the way to the tip of Argentina in the south. – Latin America was the name given to the area in the nineteenth century by the French to discourage British interests in the region. • The name has stuck, and serves to help define the region as the languages spoken throughout Latin America are Latin based languages. – Spanish – ¾ of Latin Americans speak Spanish. – Portuguese – The other quarter, primarily in Brazil speak Portuguese. Relative Location Different Regions • For our purposes we will look at Latin America in two separate regions, each with their own subregions: – Middle America • Mexico • Central America – South America • • • • Caribbean North Andean West Brazil Southern Cone Regions of Middle America Mexico Central America Middle America Mexico Mexico City Mexico Acapulco Mexico • • • • • • • Guatemala Belize Honduras El Salvador Nicaragua Costa Rica Panama Central America Regional Disputes • Despite apparent shared physical characteristics and shared colonial and economic backgrounds, the region of Latin America is contested and unclear. – Two clear physical breaks are typically used to separate regions. • the isthmus of Tehuantepec in Mexico • the isthmus of Panama in Panama Regions of South America Caribbean North Colombia Venezuela Guyana Suriname French Guiana Andean West Peru Ecuador Bolivia Brazil Southern Cone Argentina Chile Uruguay Paraguay Excluding Nations • At times the Latin distinction is used to disqualify some countries from being included in the region described as Latin America. – Belize and Guyana – English Speaking – French Guiana – French Speaking – Suriname – Dutch speaking, and still under Dutch political control • For our purposes though we will included these countries in our review of the region.

Physical Geography • LAND BRIDGE – Serves as a land bridge connecting North America with Latin America • NATURAL HAZARDS – Some of the physical features leave the area exposed or prone to the following natural hazards: • EARTHQUAKES • VOLCANOES • HURRICANES I wonder why? Physical Geography Mexico • Three major mountain ranges dominate Mexico: – – – • Between these ranges stretches the Mexican Plateau (Also called Mesa Central) – • Sierra Madre Occidental Sierra Madre Oriental Sierra Madre del Sur Provides flatter, cooler and wetter environments for agriculture and settlement. On both the Pacific and Gulf coasts lie many resort towns which draw huge tourism business. Physical Geography Middle America • • Tectonic activity along the Sierra Madre produces earthquakes and volcanic activity in this region. Caribbean Sea and Pacific Oceans sandwich the narrow landscape. – This does provide opportunities for tourism, but also for threat from hurricanes. Plate Tectonics Distribution of Earthquakes and Volcanoes Physical Geography The North - Caribbean South America • This area is dominated by three major features: – Lake Maricaibo – Which can be seen on many satellite images. World class oil deposits lie here (about 4% of the worlds oil reserves), and just off the coastal areas in Venezuela. – Llanos – An important grassland region right in the middle of Venezuela – Orinoco River – Flows along the Guiana Highlands splitting Venezuela, and into the Caribbean Sea. Physical Geography The West – Andean South America • Andes Mountains – Dominate the region – Slow westward drift of the South American plate colliding with the Nazca plate causes SA plate to uplift thus creating the Andes Mountains. • Lake Titicaca – Located on the border of Peru and Bolivia – Highest commercially navigable lake in the world at 12,507 ft. above sea level. Physical Geography Brazil • Amazon Basin – Covers more than 2.3 million sq. miles. – The river and its tributaries carry about 20% of the worlds freshwater supply. • Mato Grosso Plateau – Contains mainly savannah and grassland, stretching from the Amazon to the Brazilian Highlands • Brazilian Highlands Physical Geography The South – Southern Cone • Atacama Desert – Rainshadow effect and wind patterns make this desert in Chile one of the driest places on earth. • – – • – • Fertile lowlands on the foothills of the Andes mountains. Lush grasslands receiving enough rainfall making soil appropriate for agriculture. Patagonia – • Andes Mountains • Tierra del Fuego – Separated from southern most point of South America by the Strait of Magellan Pampas Area includes Andes mountains to the west and plateau lands in the east. Plains are almost bare of vegetation and mainly inhospitable. Mt. Aconcagua – Tallest mountain in the Andes range at 22,834 ft.
