Chapter 9 Study GuideProfessionals who study and make predictions about human populations are called what _______________________.Using page 219 in the textbook, when did the human population double from 2 billion to 4 billion (Look at the graph at the bottom of the page and count the number of years)?Which factor contributed most to exponential human population growth?More food, better hygieneHigher birth ratesHigher fertility ratesIncreased immigrationA population pyramid is created how:Educating women worldwide has lowered birthrates partly becauseEducated women bear many children to ensure some surviveEducated women may learn family-planning techniquesEducated women contribute less to their family incomeAll of the aboveUsing page 219 in the textbook, what period of human history was the population growth most rapid (Look at the graph at the bottom of the page and pick one of the periods at the top to decide which had the highest population growth)?Using page 227 in the textbook, the 1991 cholera outbreak in Lima, Peru was caused by what?Because birth rates have begun to fall Earth’s population willSoon stabilize at the level it is today – about 6 billionBegin to decrease until it reaches 5 billionIncrease for a short time and then decrease to current levelsStabilize somewhere around 9 billion by 2050Using page 229, which country has the fastest growing population?Which of the following makes it difficult to reduce population growth?High literacy rates result in women wanting to have more childrenPopulation sizes will not decline until some people start having to do without food and other necessities of lifeMany people live in cities, where large families are an advantageMany people have low literacy and limited access to healthcareUsing page 230, list 4 strategies that some countries have used to slow population growth.Define migration.Define infrastructure.Define urbanization.Define survivorship.Define age structure.Define least-developed countries.Define life expectancy.Define arable land.Define demographic transition.An increase in water-borne diseases could possibly be alleviated byAdequate sewage treatment facilities for growing populationsVery rapid growth of large citiesSufficient fuelwoodBoth a and bWhich of the following is a reason that wood is considered a limited resource in many developing countries?Wood is used in place of money to buy foodFuelwood allows people to purify their water by boiling itExcess wood is used to construct shantytownsPeople cut down trees faster than they can growSince 1970, fertility rates haveIncreased in both more-developed and less developed countriesIncreased in more-developed and decreased in less-developed countriesDecreased in both more-developed and less-developed countriesDecreased in more-developed and increased in less-developed countriesScientists predict population sizes by usingSurvivorship, migration, life expectancy, and replacement structureLife expectancy, age structure, fertility rates, and migrationReplacement rate, fertility rate, age rates, and survivorshipAge structure, survivorship, fertility rate, and migrationAge structure data include all of the following exceptMembers of a population who are between 5 and 11 years oldThe ratio of males to females in a populationThe amount of population change due to immigration or emigrationThe ratio of older people to younger people in a populationDefine immigration.Define population pyramid.Define suburban sprawl.Define industrialization.Define exponential growth.Word Bank (Questions 31-42)?social, economic?medium, 9 billion?arable land?slowly or not at all?fertility rates?fourth?least-developed?scientific, industrial?life expectancy?replacement level?population pyramid?sterilizeThe __________________________ is the average number of children each parent must have in order to replace themselves in the population.An increase in population could result from increased birth rate, increased ___________________________, or immigration.During _______________________ stage of demographic transition, the birth rate drops and the size of the population begins to decrease.The _______________________ and ______________________ revolutions brought about changes that caused exponential growth of the world human population.A shortage of _________________________________ can decrease the food supply available to a growing population.The United Nations has designated ___________________________ countries to be given priority for foreign aid.One way to stabilize the world population is to reduce _________________________________________ by improving women’s status and educational opportunities.Many demographers predict a(n) ______________________________ population growth rate and a world population of _____________________________ in 2050.A _________________________________ helps demographers predict which age groups will experience the most growth.Type I and Type III survivorship curves indicate populations that are growing ___________________________________.An adequate supply of fuelwood helps to prevent disease by allowing water to be boiled to _____________________ it.The theory of demographic transition is based on the idea that industrial development causes ___________________________ and ______________________ progress that affect population growth rates. ................
