The annual fluctuation in carbon dioxide concentration can best be explained by:

• Seasonal use of fossil fuels

• Regularity of volcanic activity

• Deforestation in the tropics

• Seasonal photosynthetic activity of green plants

• El Niño events

Which of the following best explains the impact of climate change on polar regions?

• Polar regions are warming more slowly than other regions because the ice and snow keep the air cool.

• Polar regions are warming more slowly than other regions because atmospheric circulation wind patterns trap cold air at the poles.

• Polar regions are warming more quickly than other regions because more carbon dioxide can dissolve in colder water.

• Polar regions are warming more quickly than other regions because warming decreases the coverage of high-albedo ground cover like ice and snow.

The table shows the balanced chemical equations that represent three processes that are part of the nitrogen cycle. Which of the following is exemplified by the equations above?

• Approximately 10% of energy is transferred from one trophic level to the next.

• In a food web, energy flows and matter is cycled.

• Each biogeochemical cycle demonstrates the conservation of matter.

• The major reserve for nitrogen is in the atmosphere.

Based on the diagram, which of the following best describes the most likely direct effect of a decline of the small fish population on the marine food web?

• he jellyfish population will experience local extinction because of a lack of food resources.

• The jellyfish population will increase because of decreased predation.

• The jellyfish population will migrate to an area with more available habitat for eggs.

• The jellyfish population will decrease from the increase in the sea turtle and tuna populations.

Based on the data in the graphs, which of the following best describes the relationship between concentration and Antarctic temperature?

• A decrease in concentration preceded an increase in Antarctic temperature.

• An increase in Antarctic temperature preceded a decrease in concentration.

• There is a direct relationship between concentration and Antarctic temperature, but causality cannot be determined.

• There is an inverse relationship between concentration and Antarctic temperature, but causality cannot be determined.

Based on the diagram, which of the following best illustrates how the biosphere can affect global climate change?

• Glaciers and snow reflect back the Sun’s energy, decreasing the amount of sunlight absorbed and decreasing the surface temperature.

• Greater amounts of incoming radiation reach Earth when the ozone is depleted, increasing the rates of skin cancer and cataracts in humans.

• 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.

• Warmer atmospheric temperatures decrease cloud cover, reducing the volume of global precipitation

The diagrams above show an area that was once a pasture that has since undergone changes to the vegetation over time. Which of the following changes in the hydrologic cycle is most likely to occur as a result of the change in vegetation in the area?

• Increased infiltration

• Increased runoff

• Decreased transpiration

• Decreased precipitation

How does the burning of fossil fuels contribute to the net increase in atmospheric carbon?

• Photosynthesis is reduced by virtue of increased smoke and haze.

• Carbon released by the burning is not in a form that can be readily absorbed by plants, leaving residual carbon in the atmosphere

• Carbon that has been sequestered underground is added to the carbon cycling between the atmosphere and the biosphere

• Carbon released by the burning is more easily absorbed in the atmosphere than that produced by natural means

• Carbon released by the burning increases plant growth, producing more carbon for the atmosphere.
