What are the two most common gases found throughout the atmospheric layers?

• carbon dioxide and oxygen

• ozone and water vapor

• nitrogen and oxygen

• carbon dioxide and nitrogen

Solar energy is absorbed by land and bodies of water on Earth before it radiates back into the atmosphere in the form of heat. What happens to some of the heat that radiates back into the atmosphere?

• It is absorbed by the clouds, causing precipitation.

• It is absorbed by water vapor in the atmosphere, causing condensation.

• It is trapped by the ozone layer, causing an increase in the temperature.

• • It is trapped by the gases in the atmosphere, causing the greenhouse effect.

    It is trapped by the gases in the atmosphere, causing the greenhouse effect.

A teacher displays two charts on the board, as shown. Chart 1 shows the major greenhouse gases that are added to the atmosphere due to human activities, and Chart 2 shows the composition of air.

Which component of the atmosphere will likely increase due to additional greenhouse gas production?

• Argon gas

• Nitrogen gas

• Oxygen gas

• Trace gases

Examine the pie chart showing the composition of the atmosphere labeled W, X, Y, and Z.

Which portion of the pie chart represents nitrogen gas?

• W

• X

• Y

• Z

Some scientists have hypothesized that global temperature changes are part of a larger, natural cycle that the Earth has gone through regularly over its history. The graph shows data for both global temperature and carbon dioxide concentration from 1880 to 2010.

What other hypothesis might be supported by this data?

• Sulfur dioxide levels have also increased from 1880 to 2010 adding to Earth’s average temperature increase.

• Increasing levels of carbon dioxide have caused Earth’s temperature to rise steadily from 1880 to 2010.

• The Earth has cooled steadily from 1880 to 2010 even as carbon dioxide concentrations have risen.

• There is no pattern in either temperature or carbon dioxide concentration from 1880 to 2010.
