Unit 5 Test Review En SC

The human population has grown rapidly over the past two centuries and has not leveled off.  When the population is graphed, the data forms a J-curve, which indicates a steady increase followed by exponential growth.  Which of the following graphs most likely shows human population growth over the past two centuries?

Top Left is A and Bottom Left is B

According to the overpopulation article that we read, which of the following statements are FALSE?

• The global population is declining because the quality of healthcare is declining.

• A reason populations are growing at such a fast rate is because people are living longer.

• Population levels are much more of a problem than the amount of resources humans use.

• Richer (more developed) countries tend to use more resources.

The human population has been growing exponentially and has not leveled off.  We are continually increasing our carrying capacity (the number of humans that the earth can support).  Which TWO of the following are ways in which humans have increased our carrying capacity?

• improvements in medicine

• global warming

• improvement in agriculture

• increasing greenhouse gas emissions

A population pyramid shows the distribution of a population in a region by age and gender.  Which statement about the population pyramid below is TRUE?

• The population is young and growing with high fertility rates and lower than average life expectancies.

• The population is not growing with low birth rates and high quality of life (good health care, access to healthy food, etc.)

• The population has a much higher number of males than females.

• The population has the exact same number of people in each age group.

Since the 1900's, global carbon dioxide emissions have been increasing at about the same rate as the human population.  Increased carbon dioxide emissions is largely responsible for increased global temperatures (global warming).  Which effect could global warming have on our planet?  (NOTE: more than one response may be true, so be sure your response answers the question that is being asked.)

• melting of polar ice caps and therefore rising of sea levels

• a decrease in the severity of major storms such as hurricanes

• an increase in the earth's carrying capacity

• The planet is not affected by global warming.
