Multiple Choice

What effect did the industrial revolution have on our environment?

• It resulted in the release of large amounts of oxygen into the atmosphere

• It resulted in large amounts of carbon dioxide into the atmosphere

Multiple Choice

• Burning coal

• Burning oil

• Burning forests

• all of the above

Multiple Choice

Why is the Keeling Curve not just a straight line?

• In the winter, people use more fossil fuels to keep warm.

• In the winter, trees go dormant and do not remove carbon dioxide from the atmosphere through photosynthesis

• Combination of both previous answers

• None of the above

Multiple Choice

What did the Keeling's Curve show?

• The level of carbon dioxide in the atmosphere was decreasing

• The level of carbon dioxide in the atmosphere was increasing

• The level of carbon dioxide in the atmosphere remained the same

Multiple Choice

What did data from ice cores show?

• The amount of atmospheric carbon dioxide has not changed over time

• The amount of atmospheric carbon dioxide began decreasing after the industrial revolution

• The amount of atmospheric carbon dioxide began increasing after the industrial revolution.

Multiple Choice

What did the ice core data show about the relationship between increased levels of atmospheric carbon dioxide and global temperature?

• The more atmospheric carbon dioxide there is, the higher the global temperature.

• The more atmospheric carbon dioxide there is, the lower the global temperature. .

• There is no relationship between atmospheric carbon dioxide and global temperatures.

Multiple Choice

Why is atmospheric methane not as much a problem as carbon dioxide?

• Because its residency time in the atmosphere is a lot longer than carbon dioxide

• Because its residency time in the atmosphere is a lot shorter than carbon dioxide

• Because it is not increasing in the atmosphere

Multiple Choice

• 10%

• 25%

• 50%

• 1 degrees Fahrenheit

• 10 degrees Fahrenheit

• 100 degrees Fahrenheit

• 1,000 degrees Fahrenheit

Multiple Choice

Why is this phenomenon no longer called global warming?

• Because the Earth's temperature is not really getting warmer.

• Because while the average global temperature is increasing, in some places it is getting colder.

Multiple Choice

How do we know that the increase in atmospheric carbon dioxide is due to human activities?

• Careful record keeping of the amount of coal and oil that has been extracted and sold

• Wall Street has an invested interested in keeping the fossil fuel industries strong

• Fossil fuels are some nation's main export

• Some politicians are paid to protect fossil fuels

• All of the previous
