An increase in carbon dioxide in the atmosphere is associated with an increase in global temperature. Which property of carbon dioxide is responsible for this temperature increase?

• Carbon dioxide transmits more sunlight than other atmospheric gases.

• Carbon dioxide efficiently turns sunlight into heat.

• Carbon dioxide keeps heat in the atmosphere from escaping into space.

• Carbon dioxide stores solar energy in chemical bonds.

The table shows the concentrations of two greenhouse gases in the atmosphere recorded in 1850 and 1986 and the estimated values for the year 2100. Based on the data, what can be predicted about the likely effect of greenhouse gases on Earth’s future climate?

• The temperature of Earth will not change, and the climate will remain the same.

• The temperature of Earth will vary, and the climate will remain the same.

• The temperature of Earth will likely increase, and the climate will be warmer than the present.

• The temperature of Earth will likely decrease, and the climate will be cooler than the present.

Ice molecules take up more volume than liquid water molecules. Which of these conditions occurs when water in a pond freezes?

• Water molecules solidify at the bottom and push the liquid water upward.

• Water molecules solidify near the surface and float on the liquid water.

• Water molecules break apart into solid oxygen and solid hydrogen.

• Water molecules form solids when they combine with dissolved minerals.

How does the Gulf Stream affect weather in Florida?

• The Gulf Stream helps weather to be cooler in the fall.

• The Gulf Stream helps weather to be cold during the winter.

• The Gulf Stream causes weather to be rainy during the spring.

• Global temperature will increase by 0.2°F.

• There will be no change in global temperature.

• Global temperature will decrease by 1.0°F.

El Niño is a term that refers to the oceanic phenomenon in which the surface water temperatures increase. The increase in water temperature usually occurs in the tropical Pacific Ocean. Which will most likely occur as a result of this phenomenon to cause environmental changes?

• melting of the polar ice caps

• varied atmospheric conditions

• an increase in volcanic eruptions

• an increase in the length of summers

Which difference between water and ice results in ice floating on cold water?

• heat

• shape

• density

• volume

What can be inferred based on an analysis of the model?

• More carbon is released by the ocean than is being absorbed.

• Excessive vegetation growth is increasing the amount of carbon in the atmosphere.

• Excessive use of fossil fuels is disturbing the balance of carbon in the atmosphere.

• Changing land use has the greatest impact on atmospheric carbon.
