What you know: 1. Green revolution: intro of scientifically bred or selected varieties of grain that can greatly increase crop yields. 2. Things that cause seasons on earth: earth tilted on axis, sun distribution 3. Large scale hydroelectric projects around the world: 3 gorges dam, dams going on in india 4. Age distribution diagrams: ZPG=looks like a building that doesn’t change, bottom same as top. Slow growth=base a bit longer than top but not quite a pyramid. Rapid growth=WIDE base, narrow top, like a pyramid 5. Waste water treatment process: get water, drain out sludge, have sludge area, water goes through process to get more sludge out, water gets aerated, water gets filtered with Cl to remove bacteria. …show more content…
Rule of 70: 70/percent=time it will take to double population 9. Replacement level fertility: reproducing enough babies to replace yourself(in developed countries, it’s 2.1, but in developing, it’s 2.5 because of infant mortality) 10. Waste created by nuclear power plants: radioactive waste in solid liquid or gas state 11. Biggest threats to biodiversity: HIPPO, habitat loss, invasive species, population growth, pollution, and overexploitation 12. Integrated pest management: people come in and solve your pest problem without using harmful chemicals or pesticides. Situations are situation specific and take a longer time to solve. 13. Aquaculture: trapping fish in a coast, or netted fenced area of water to use for produce and food or commercial use 14. Demographic transition model: preindustrial, transitional, industrial, postindustrial. Pre- high birth and death rates. Trans- high birth rates and low death rates. Ind- lower birth rates, and same death rates. Post- birth and death rates equal 15. Photosynthesis: CO2+H2OO2+C6H12O6. Needs solar energy 16. Half life: radioactive decay of how long it takes for half of material to …show more content…
Biomagnifications: increase in concentration of DDT, PCBs, and other slowly degradable far soluble chemicals in organisms at successively higher trophic levels of a food chain or web. 26. Efficiency of an incandescent lightbulb (5%), photosynthesis (1%), coal power (33%) 27. Fecal coliform bacteria: various strains of E. Coli to detect the presence of infectious agents in water 28. Consequences of SO2, lead, O3 in troposphere, and particulates: SO2- breathing problems, visibility reduction and aggravation of asthma, damages crops, trees, soils, and lake aquatic life, corrodes metals and damages paint, paper, and leather and stone on buildings. O3- coughing, breathing problems, reduces resistance to colds and pneumonia, irritates eyes, nose, and throat, aggravates asthma, bronchitis, emphysema and heart disease and damages plants, rubber in tires, fabrics and paints. Particulates- irritate the nose and throat, damage lungs, aggravate asthma and bronchitis, shortens life. Lead- mutations, reproductive problems, cancer, nervous system damage, mental retardation and digestive and other health problems, reduce visibility and corrode metals and discolor clothes and
