<ul><li><p> Photo by Linda Hammon</p></li><li><p>Latin America Latin America can be divided into 3 sub-regions:</p><p>Central America &amp; Mexico (Mexico + 7 Countries)</p><p>The Caribbean (Bahamas, Greater/Lesser Antilles, West Indies)</p><p>South America </p></li><li><p>Lowlands of the Amazon River basin hold many rich, natural resources including species found nowhere else &amp; possible treatments for a # of diseases. The Amazon River Basin is the largest rainforest in the world.</p><p>The Amazon RiverSecond longest river, and largest by waterflow</p></li><li><p>Main source of the Amazon River (Iquitos, Peru)Why here???</p></li><li><p>Lake TiticacaLake Titicaca is in the Andes MountainsA number of lowlands &amp; river basins to the east, fed by runoff from the Andes</p></li><li><p>Bodies of WaterAtlantic OceanPacific OceanGulf of MexicoCaribbean SeaAmazon R.Orinoco R.Uruguay R.Magdalena R.Sao Francisco R.Lake TiticacaLake MaracaiboRio de La PlataParana R.</p></li><li><p>Amazon River BasinReasons for deforestation:Subsistence farmersCommercial farming &amp; loggingGovt policiesWorld Bank mistakes</p><p>http://www.youtube.com/watch?v=olmzzWo0wps</p></li><li><p>The Amazon contains sources of lumber, gold, and gems.Countries with poor economies have reason to exploit, not preserve.Spontaneous fires are also a danger here.Fires burning in the Amazon Basin</p></li><li><p>Destruction of the Amazon Basin has occurred at an alarming rate and in a number of countriesBecause the problem is multinational, any solution will take cooperative efforts.</p></li><li><p>In the isolated regions of the Guiana Highlands (as in the Amazon River Basin), there are many indigenous groups with unique lifestyles.These tribes are an example of ?</p></li><li><p>Mountains and PeaksAndes Mts.Sierra Madres Mts.Guiana HighlandsBrazilian HighlandsPatagonian Plateau</p></li><li><p> Andes Mtn RangeWorlds highest range outside of Asia which implies that they are ?</p><p>Longest range in the world</p></li><li><p>Most people in the Andes live below 11,500 feet.

WHERE is it? Peru in the Andes Mountains</p><p>9AAlthough Mexico is technically part of North America, it is culturally more similar to South America, so this region is known as Latin America. Latin America is 3x the size of the USABrazil is the largest country with about of the population of South America living here. *Average discharge of 7,381,000 cubic feet/second Largest drainage basin in the world (2.7 million square miles) 150 miles wide at its estuary (where it empties into the Atlantic)</p><p>More water flows through the Amazon than the next 7 rivers (in terms of flow) combined</p><p>Three-toed sloths are found nearly exclusively in the Amazon rainforest.</p><p>The flowering four oclock (lower left picture) is a treatment for rheumatoid arthritis. Some researchers believe that the cure for cancer may be found in the rainforest.World Geography South America - Chapters 12 &amp; 13llhammon*Why here? Runoff from AndesWorld Geography South America - Chapters 12 &amp; 13llhammon*Tatora Reed boats on Lake Titicaca Lake Titicaca is at 12,507 feet elevation</p><p>Andes are the source for a number of bodies of water (see the next slide)</p><p>World Geography South America - Chapters 12 &amp; 13llhammon*Numerous important bodies of water in L.A. many rivers originate in the Andes and flow east across S.A., providing water resources for the interiorWorld Geography South America - Chapters 12 &amp; 13llhammon*The Amazon rainforest is being destroyed in many tropical countries - the majority of deforestation results from the actions of poor subsistence cultivators.in Brazil only about one-third of recent deforestation can be linked to "shifted" cultivators. Historically a large portion of deforestation in Brazil can be attributed to land clearing for pastureland by commercial and speculative interests, misguided government policies, inappropriate World Bank projects, and commercial exploitation of forest resources. </p><p>Video on this slide is one I showed back at the beginning of the year </p><p>World Geography South America - Chapters 12 &amp; 13llhammon*The desire to increase their countries wealth and resources also endanger efforts to save the rainforest. How do we (the UN, for instance) tell a country that they cant exploit resources within their own borders?</p><p>Spontaneous fires result from careless campers/hikers, as well as ligtning strikes. They destroy animal habitats and increase soil erosion, as well as harm the regions economy due to the expense of fighting fires and homes/businesses lost.World Geography South America - Chapters 12 &amp; 13llhammon*Which countries are seeing deforestation? Venezuela, Colombia, Peru, Bolivia, Guyana, Brazil</p><p>Focusing solely on the promotion of sustainable use by local people would neglect the most important forces behind deforestation in Brazil.Global interests in the rainforest must be addressed.</p><p>World Geography South America - Chapters 12 &amp; 13llhammon*Although the damage is significant, the rate of deforestation has been slowing in the past decade.World Geography South America - Chapters 12 &amp; 13llhammon*These diverse groups still speak their native languages, hold native beliefs, dress, etc. Many live on protected reserves.</p><p>This is an example of cultural divergence Isolation has allowed these groups to retain their unique nature, protecting them from assimilation into the urban, European population</p><p>One result of deforestation in the Amazon is that these areas are now being exposed to outisiders.</p><p>World Geography South America - Chapters 12 &amp; 13llhammon*World Geography South America - Chapters 12 &amp; 13llhammon*Longest continental mountain range in the world (4300 miles long Venezuela to Argentina). Average height of 13,000 feet. Worlds highest range outside of Asia. The highest peak, Mount Aconcagua, rises to an elevation of almost 23,000 feet (22,834). More than 50 volcanoes the highest volcanoes in the world.</p><p>This is a YOUNG mountain range formed 18-25 million years ago. (For comparison, the Rockies are 55-80 million years old.)</p><p>Which aspect of LEMPOSA explains that snowcapped mountains? Elevation</p><p>Highlands climates- For every 1000 ft. of elevation, temperature decreases by 3 degrees. </p><p>World Geography South America - Chapters 12 &amp; 13llhammon*La Paz about 20,000 peopleCuzco about 300,000 people</p><p>Q: Ask students why most people live in Cuzco as opposed to LaPazA: Because Cuzco is below 11,500 and breathing there is easier. Outsiders visiting La Paz require oxygen to breathe. </p><p>Mat, tea made with coca leaves, helps to relieve altitude sickness (Mat tea is made in other parts of S.A. without coca.)World Geography South America - Chapters 12 &amp; 13llhammon*What grows in each altitude region? Students should know this from the reading Chart on page 259 purple book There WILL be questions on this on the testWorld Geography South America - Chapters 12 &amp; 13llhammon*Patagonia Southern Argentina and ChileL = latitudeQ: Why do you suppose LA has such a wide array of climate regions? A: The region is LONG and covers multiple latitudes</p><p>World Geography South America - Chapters 12 &amp; 13llhammon*Mediterranean like Greece or Italy Warm and conducive to growing things Hot, dry summers and cool, wet winters</p><p>Whys the climate so nice? Proximity to Water</p><p>Temperate climate types contribute to the vast grassland regions in Chile, Argentina, and Brazil (like the Pampas)World Geography South America - Chapters 12 &amp; 13llhammon*World Geography South America - Chapters 12 &amp; 13llhammon*The Atacama desert is the worlds driest </p><p>World Geography South America - Chapters 12 &amp; 13llhammon*To the west of the Andes kept dry by the Humboldt current (COLD OCEAN CURRENT). Pair this with a minor Mountain Barrier effect on the leeward side of the Chilean Coast Range. Andes block moisture coming from the Amazon.</p><p>Q: What element of LEMPOSA do the photos above illustrate? A: M Mountain BarrierWorld Geography South America - Chapters 12 &amp; 13llhammon*World Geography South America - Chapters 12 &amp; 13llhammon*Panama Canal isnt natural but was built at the Isthmus, the narrowest point. It was built by the U.S. 1904-1914, but now belongs to Panama. The illustration (red lines) show how much distance was saved by creating the canal through Panama. </p><p>A ship entering the Panama Canal from the Pacific side enters it from the East, and exits on the Atlantic, but facing back East. Due to the curvature of the canal. </p><p>They may know Angel Falls from the movie Up World Geography South America - Chapters 12 &amp; 13llhammon*Charles Darwin did his studies of animal &amp; plant diversity here, as it is home to numerous unique species (some now endangered) like the Giant Galapagos Tortoises which grow to 880 lbs. and almost 6 over their 100+ year lifetime</p><p>World Geography South America - Chapters 12 &amp; 13llhammon*The following slides go with the graphic organizer. </p><p>1. Andes Mountains, Amazon River, mountain barriers, etc.2. People live where they can farm, make a living, habitable land. </p><p>World Geography South America - Chapters 12 &amp; 13llhammon*World Geography South America - Chapters 12 &amp; 13llhammon*World Geography South America - Chapters 12 &amp; 13llhammon*Mountain range in Bolivia?
