  1. GEOG 101: Day 9 Midterm Review

  2. Housekeeping Items • I will return your outlines. I’m sorry I spilled coffee on many of them. Please note: I would like you to return them with your final project so I can see if you took my comments into account. • There are some very interesting projects and I am looking forward to seeing the final products. • I saw some thing in the paper yesterday that crystallizes one of the key issues in developing countries and, to a lesser degree, in developed countries. In Haiti the government banned the sale of plastic bags and styrofoam food containers, but the sellers of these ignored the ban, claiming that they had no other livelihood. • I came across a recent book that claims that women are the key to successful Third World development: Half The Sky: Turning Women’s Oppression into Opportunity Worldwide (Vintage 2010). There’s also a web site: http://www.halftheskymovement.org/.

  3. Review for the mid-term (next Wednesday) • For the mid-term we will be covering Chapters 1, 3, 4, 6-8, but not 2 and only a little bit of 5. Review these chapters and the lecture notes.

  5. QUESTION: Interpreting Graphs and Data What happens if test results reject a hypothesis? The scientist formulates a new hypothesis It shows the test failed The hypothesis was supported The predictions may not have been correct 1-5

  6.

  7. QUESTION: Weighing the Issues • ∙Do you think the rest of the world can have an ecological footprint as large as the footprint of the Canada? • Yes, because we will find new technologies and resources • Yes, because the footprint of Canada is not really that large • Definitely not; the world does not have that many resources • It does not matter; it’s not that important 1-7

  10. QUESTION: Review • Which of the following is a correct statement? • Energy and matter flow in one direction only • Energy and matter both cycle repeatedly • Energy flows in one direction, while matter recycles • Matter flows in one direction, while energy recycles • What is the definition of “net primary production”? • Assimilation of energy by heterotrophs • Elements and compounds that are required for survival • Energy remaining after respiration that is used to generate biomass • Assimilation of energy by autotrophs 5-10

  11. QUESTION: Review • What are ecosystem services and what are some examples? • Regulation of balance of gases in the atmosphere • Filtration/ purification of water, air, and soil • Regulation of water cycle • Prevent soil erosion and protect against storms, floods and droughts • All of the above • What are key carbon sinks (in a positive sense) that are being disrupted by human activity? • The atmosphere • The oceans • Forests, especially boreal and tropical • B and C 5-11

  12. QUESTION: Review • Which biogeochemical cycle is contained in proteins, DNA and RNA? • Carbon • Nitrogen • Water • Phosphorus • Which biogeochemical cycle is being affected by damming rivers, and altering the surface and vegetation? • Carbon • Nitrogen • Water • Phosphorus 5-12

  13. QUESTION: Interpreting Graphs and Data According to this graph, which ecosystem has the warmest temperature and most rainfall? a) Temperate grassland b) Boreal forest c) Savannah d) Tropical rain forest FIGURE 5.9 5-13

  14. QUESTION: Review What has accounted for the majority of the world’s population growth in recent years? a) Women are having more babies b) Death rates have dropped due to technology, medicine, and food c) More women are using contraceptives d) Nothing, the population has dropped in recent years According to the I = P x A x T formula, what would happen if China’s 1 billion people had a lifestyle like Canadians? a) Their population would automatically drop b) Their population would automatically increase c) Their affluence and technology would increase d) Their impact on the environment would even out

  15. QUESTION: Review How have humans been able to raise the environment’s carrying capacity for our species? a) Through technology b) By eliminating limiting factors c) Through increased consumption d) Spending more money on non-essential resources Areas that lack significant numbers of people, and have a low population density are… a) No longer available b) Best able to support higher densities of people c) Sensitive areas least able to support high densities of people d) Located around tropical and grassland areas

  16. QUESTION: Review Describe the relationship between growth rates and population size. a) Falling growth rates automatically mean a smaller population b) Falling growth rates automatically mean a larger population c) Falling growth rates means we no longer have a population problem d) Falling growth rates does not mean a smaller population, but that rates of increase are slowing

  17. QUESTION: Interpreting Graphs and Data What happens during the “pre-industrial” stage of the demographic transition? • High birth and death rates rise cause population increases • High birth and death rates, but population is stable • High birth rates with low death rates cause population to increase • Low birth and death rates cause the population to decrease

  21. QUESTION: Review Erosion increases through all of the following, except: Excessive tilling Overgrazing Clearing forests All of the above increase erosion Which sustainable farming method involves planting rows of trees along field edges to slow the wind?

  25. QUESTION: Review How does GM food production differ from traditional, selective breeding? • It does not differ • It uses genes from different species • It involves more fieldwork • It works better in developing countries What is a “seed bank”? • An institution that preserves seed types for their genetic diversity • A form of banking in developing countries, where people can put their excess seeds up as collateral for a loan • A form of genetically modified organism • An area where livestock are fed high-quality grains

  26. QUESTION: Review Which of the following is the fastest growing type of agriculture? • Concentrated animal feeding operations • Sustainable agriculture • Aquaculture • Monocultures Given that the green revolution has increased crop yields, but only by using increased fertilizers, pesticides, irrigation, and hybrid seed, do you consider it a success? • Yes, because more people were fed, regardless of the price • Yes, because industrialized countries can help through education and technology • No, we will have to eventually pay the environmental costs of producing food in this way • It does not matter; I can buy food whenever I want
