apes unit 9 - test answers
Which of the following best identifies the reason that chlorofluorocarbons (CFCs) were banned in 1996 by the Montreal Protocol?
CFCs led to the destruction of stratospheric ozone.
Which of the following environmental problems is most directly linked to ocean warming?
Coral bleaching
Which of the following best describes an advantage of constructing habitat corridors?
Corridors connect habitats separated by fragmentation and connect wildlife populations.
Which of the following best describes how an anthropogenic activity can increase ocean acidification?
Emissions from power plants that burn fossil fuels increase atmospheric carbon dioxide, which is absorbed by the ocean.
Which of the following best describes the greenhouse effect on Earth?
Greenhouse gasses trap heat near Earth's surface, keeping the average surface temperature constant.
Which of the following best describes the advantage of using hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs) to replace chlorofluorocarbons (CFCs) in industrial processes?
HFC and HCFC have lower ozone-depleting potentials than CFCs do.
Which of the following events would most likely lead to a decrease in the pH in the oceans?
Increased burning of fossil fuels in power plants
Which of the following best describes the primary cause of global ocean warming?
Increased global temperature from an increase in greenhouse gasses in the atmosphere
Which of the following types of releases of greenhouse gasses from an anthropogenic source is shown in the diagram?
Industrial and agricultural practices releasing CH4 into the atmosphere
The data in the graph reflect threats identified in species recovery plans. Based on the data in the graph, altering human activity in which of the following areas will most benefit plant species?
Introduction of invasive species
Based on the data above, which of the following is the most likely conclusion of a study addressing the following scientific question. What will happen to methane levels in the atmosphere at 60°N to 75°N latitude from 2018 to 2027 if the trend from 2011 to 2017 continues?
Methane levels in the atmosphere will increase because melting or thawing permafrost will lead to an increase in the amount of organic matter that will decompose.
Which of the following best describes the importance of ozone in the stratosphere to life on Earth?
Ozone absorbs most of the ultraviolet radiation from the Sun.
Based on the diagram, which of the following best illustrates how the biosphere can affect global climate change?
Producers use solar energy for photosynthesis, decreasing the amount of carbon dioxide in the atmosphere and increasing the amount of carbon sequestered in plant tissue.
Which of the following best describes a disadvantage of creating a series of protected habitats in an effort to maintain biodiversity in an area?
Protected habitats often separate species inside the habitat from other populations of the same species living outside the habitat.
The map reflects the difference in annual surface temperature from 2011 to 2017 in relation to 2000 to 2010. The scatter plot reflects the average change in surface temperature by latitude from 2011 to 2017 in relation to 2000 to 2010. Based on the data above, which of the following hypotheses about the future conditions in the Arctic is most plausible if the trend seen from 2011 to 2017 continues?
The albedo will decrease.
Based on the diagram, which of the following best predicts how an increase in greenhouse gasses would affect the ocean?
The oceans would be warmed because of increased solar radiation being absorbed by the water, causing expansion and sea level rise.
Which of the following best describes why water vapor, a greenhouse gas, is not considered a significant contributor to global climate change?
Water vapor has a relatively short residence time in the atmosphere.
Stratospheric ozone (O3) is essential for life to exist on Earth because it
absorbs incoming solar UV-C radiation, preventing exposure to dangerous radiation from the Sun
Coral bleaching can be hazardous to some fish species because
coral reefs provide unique habitats for fish
