GEOG 2120 Lecture Notes - Lecture 6: Precious Metal, Atmospheric Circulation, Social Inequality
Document Summary
Climate: determined by global atmospheric circulation - equatorial low and subtropical. Itcz - rainforest, rapid growth - 1. 5 - 2m of rain annually high. Climatic variability creates hazardous geographic environments - the way that these are experienced depends on social inequality and access to resources. Orographic uplift - winds bring warm moist air off the motion, cools and condenses into rain. Rainshadows - winds lose moisture as they pass over mountain and on the other side they turn into hot dry winds creating arid conditions. Oil, coal, gas - northern mexico, colombia, brazil. Venezuela - around lake maracaibo which has 4% of oil reserves. Amazonian oil deposits - discovered in 1967, in remote forest areas in ecuador and peru. Disputes among government organizations, corporations, and indigenous groups. Major precious metal mining districts in the peruvian and bolivian andes. Has fueled much of the ecological destruction and economic growth.
