Latin America Where does the latin in Latin America come from? Physical Geography The study of the natural features of the earth’s surface, especially in its current aspects, including land formation, climate, currents, and distribution of flora and fauna.

Precipitation Temperatures Elevation HUMBOLDT CURRENT Peruvian Current Humboldt Current Peruvian Current A current of cold Antarctic water which is brought to the surface by air currents. The water that is brought to the surface is nutrient rich. It brings with it all the nutrients created from sinking decomposed organic matter. During this season the water temperature drops from around 70°F (21°C) to 80°F (27°C) – December to May, down to around 65°F (18°C) to 75°F (23°C) – June through November. Vertical Climate (get your map out) Altitudinal Zonation: Vertical Climate The Tropical Hemisphere What is El Nino? (Happens every 2-7 yrs.) When trade winds lose their strengths the ocean responds in a several ways. Warm surface waters from the large, warm pool east of Indonesia begin to move eastward. Moreover, the natural spring warming in the central Pacific is allowed to continue and spread eastward through the summer and fall. As a result, the large central and eastern Pacific regions warm up (over a period of about 6 months) into an El Niño. Children of the Tropics El Nino The Effects of El Nino Effects of El Nino are increased rainfall across the southern tier of the US and in Peru, which has causes destructive flooding, and drought in the West Pacific, sometimes associated with devastating brush fires in Australia. Observations of conditions in the tropical Pacific are considered essential for the prediction of short term (a few months to 1 year) climate variations. Graphic of El Nino El Nino The El Niño temperature anomaly of 1997-98 (appearing here as a red band in the Pacific Ocean) affected weather worldwide. His sister, La Nina During La Niña years, the trade winds are unusually strong due to an enhanced pressure gradient between the eastern and western Pacific. As a result, upwelling is enhanced along the coast of South America, contributing to colder than normal surface waters over the eastern tropical Pacific and warmer than normal surface waters in the western tropical Pacific. La Nina Columbian Exchange (old NAFTA) NAFTA (North American Free Trade Agreement) NAFTA has eliminated trade barriers, increased investment opportunities, and established procedures for resolution of trade disputes. Most important, it has increased the competitiveness of the three countries (Mexico, Canada, USA) involved on the global marketplace. Advantages of NAFTA NAFTA links 444 million people and produces $17 trillion in goods and services annually. Trade between the NAFTA countries tripled from $297 billion in 1993 to $1 trillion in 2007 Disadvantages of NAFTA Critics blame NAFTA for destroying American jobs and lowering U.S. wages. Others accuse NAFTA of exploiting Mexico's workers, destroying its farms and polluting its environment. In addition, NAFTA increases the U.S. trade deficit CAFTA (Central American Free Trade Agreement) Eliminates 80% of tariffs This means things like computers and books, which are usually more expensive in Central American countries than in the US despite lower labor and other costs, will come down in price.
