Exam 2 ch6

Which of the following statements about growth rate and population size is true? a.When the growth rate decreases, population size will increase by greater increments with each successive generation. b.If the growth rate remains steady, population size will continue to increase by greater increments with each generation. c.When the growth rate increases steadily, population size decreases steadily. d.Growth rate and population size are not related.

In 1798, Thomas Malthus argued _______.

The maximum population size that a given environment can sustain is called the _______ and is represented with the letter K.

Look at the age-structure pyramids. The numbers between the bars (in the middle of the graphs) serve as the y-axis. What do these numbers represent?

What do the bars on the graphs represent?

In 2010, how many 25- to 29-year-old women lived in Niger?

The colors of the bars on the graphs indicate the life stage of the people in that age class. What does it mean if a bar is colored blue?

The 2010 age-structure pyramid for Niger indicates that the population of Niger ________.

In Canada in 2010, which age classes contained the largest number of people?

In Canada in 2010, people between the ages of 45 and 54 made up the largest percentage of the population. What factor is most likely to have caused this bulge in the age pyramid?

Assuming that current trends continue, predict how the age structure of Canada in 2030 will likely differ from that in 2010.

Based on a comparison of the age-structure pyramids, which of the following would likely be a higher priority in Canada than in Niger?

What does the left y-axis of the graph represent?

What does the green graph line represent?

Which stage in the graph shows the greatest overall decline in death rate?

What factor would contribute to a sharp decline in death rate, such as the one shown in Stage 2?

Which stage represents the fertility transition--a period of declining fertility rates related to economic and social change?

In which stage or stages is the size of the population relatively stable?

Is the following statement supported or not supported by the data shown in the graph? The population grows most rapidly when the birth rate is significantly greater than the death rate.

Is the following statement supported or not supported by the data shown in the graph? In the future the birth rate and death rate will be balanced, so the total population will remain relatively constant.

look at item 6-7

What is the effect on fertility rates as women are empowered?

Studies have shown that family planning programs _______.

Read the following scenario and answer the question(s) below. Population growth is at the root of many serious environmental problems. From the ancient Babylonians thousands of years ago, to Thomas Malthus two centuries ago, to present day neo-Malthusians, humans seem to possess an awareness of Earth's limitations in the face of growing populations. Today, our ability to accurately quantify, monitor, and control population growth is very sophisticated. We can measure growth and make predictions about world growth with mathematical and computer models. Can we prevent disaster? Mesopotamia, Mayan, Easter Island, and 1930s U.S. midwest prairie societies all experienced "crashes" because they ________.
