Which one of the following is NOT a greenhouse gas?

• methane

• carbon dioxide

• water vapor

• nitrogen

How can the planting of new trees help reduce climate change?

The amount of carbon dioxide emissions for which an individual or group is responsible is known as a

• carbon sequestration.
• carbonic acid.
• carbon offset.
• carbon footprint.

What is the biggest danger posed by global warming to people living in coastal areas?

• increased precipitation
• increased acidity of sea water
• lack of carbon dioxide in the atmosphere
• rising sea level

Which human activity contributes the most carbon dioxide to the atmosphere?

• fishing
• breathing
• burning fossil fuels
• farming

How do fossil fuels affect the greenhouse effect?

• Burning fossil fuels decreases incoming solar radiation
• Burning fossil fuels decreases the amount of heat trapped
• Burning fossil fuels releases carbon dioxide into the atmosphere trapping more heat
• Burning fossil fuels causes less heat to be trapped

A carbon "sink" is best described as:

• a reservoir that readily releases carbon to another reservoir
• a carbon reservoir that stores more carbon that it is releasing
• something that causes carbon to leak out to the atmosphere
• a carbon reservoir that is releasing more carbon than it is taking in
