Which of the following is the primary cause of stratospheric ozone depletion?
Chlorine atoms in CFCs
Sulfur dioxide in photochemical smog
Mercury released from the combustion of coal
PANS
PANS from automobile exhaust
The stratospheric ozone layer benefits life on Earth by
absorbing 99% of incoming UV-B and UV-C radiation
contributing to the formation of ground-level ozone
holding large amounts of stratospheric moisture
binding to chlorofluorocarbons (CFCs
CFCs) and breaking down the pollutants
Which of the following best describes why there has been a reduction in ozone depletion over the last half of the twentieth century?
The United States began decreasing CFC
CFC emissions under regulations in the Clean Air Act.
Less developed countries developed a global plan to decrease CFC emissions by signing Comprehensive Environmental Response, Compensation Liability Act ( CERCLA ).
Several more developed countries signed the Kyoto Protocol as an agreement to reduce greenhouse gas emissions.
A global plan to decrease CFC
CFC emissions was enacted by signing the Montreal Protocol.
Which of the following best describes why carbon dioxide has a significant effect on global climate change?
Carbon dioxide is a highly reactive molecule.
Carbon dioxide is the largest contributor to anthropogenic greenhouse gas emissions.
Carbon dioxide has the highest global warming potential of all gases in the atmosphere.
Carbon dioxide reflects infrared radiation, which gradually heats the Earth’s surface.
Which of the following best describes the cause of the greenhouse effect on Earth?
Ocean currents redistribute heat from the equator to higher latitudes.
Ozone thinning over polar regions allows more ultraviolet (UV)
(UV) light to reach Earth’s surface.
Gases in the atmosphere absorb infrared radiation and radiate the energy back toward Earth’s surface.
Surface water temperatures in the Pacific Ocean increase off the coast of South America during El Niño years.
Which of the following gases has the greatest impact on global climate change as a result of having the highest global warming potential (GWP) ?
Carbon dioxide
Methane
Nitrous oxide
CFC's
The graph above showsCO2 measurements taken from Mauna Loa, Hawaii, and the Vostok ice core, which was drilled from ice sheets in Antarctica.
Which of the following hypotheses is best supported by the graph?
Temperatures were much colder 125,000 years ago than the average temperature over the past 400,000 years.
Temperatures were the same 125,000 years ago as they are today.
Temperatures were warmer 125,000 years ago than the average temperature over the past 400,000 years.
Temperatures were cooling at a rate 125,000 years ago that was unprecedented compared to the rate over the past 400,000 years.
Sea surface temperatures in the Caribbean Sea have increased over the past 30 years.
El Niño events
Elevated levels of atmospheric CO2
The introduction of an invasive species of coral
An increase in ocean salinity
Since 1901, the sea level across the globe has risen over 20cm. The change in sea level can be affected by land movement. Land movement itself can be caused by subsiding coastal lands, oil and water extraction, and plate tectonics. The diagram shows the relative sea level rise at various coastal locations in the United States from 1960 to 2014.
Based on the information in the map, which of the following is a likely consequence for the human population if the sea level continues to change in the same pattern?
The number of inland wetlands will increase in response to sea level rise, which will increase the ability of inland ecosystems to naturally buffer the impacts of flooding.
Coastal areas will experience a decrease in the rates of erosion and water pollution in response to sea level rise because of an increase in the absorption of nutrients from agricultural areas.
There will be a decrease in the number of respiratory and cardiovascular illnesses along the coasts because there will be an increase of water vapor in the atmosphere from the rising sea level.
There will be in an increase in the number of individuals who live in flood prone regions, and there will be an increase in the number of properties at risk of flooding.
Based on the information in the diagram, which of the following best supports the claim that a change in the duration of warm seasons would result in a higher prevalence of vector-borne diseases?
Ice sheets are melting because of increased temperatures, which is eliminating vector food sources.
A shorter warm season leads to increased competition for mates, resulting in heightened vector aggression.
Increased temperatures provide an expanded breeding range and duration, which will likely increase the size of vector populations.
Climate change has led to a decrease in vector predators, which will lead to an increase in size of vector populations.
