Climate Change and Greenhouse Effect Review

Question 1: Requires viewing the video to provide a specific answer.

Question 2: 3

Question 3: Harmful

Question 4: Requires reviewing the graphs to provide a specific answer.

Question 5: By their chemical structures; HCFCs contain hydrogen atoms, while CFCs do not.

Question 6: They deplete the ozone layer and contribute to global warming.

Question 7: Increased respiratory problems, smog, and other health issues.

Question 8: Reflection back into space, absorption by the Earth's surface and atmosphere, and trapping of infrared radiation by greenhouse gases.

Question 9: Earth's temperature and climate patterns

Question 10: 30

Question 11: Requires using the interactive to provide a specific answer.

Question 12: Requires viewing the video to provide a specific answer, but generally includes the steps of solar radiation entering the atmosphere, absorption by the Earth, emission of infrared radiation, and trapping of heat by greenhouse gases.

Question 13: Industrial Revolution

Question 14: 7,000

Question 15: True

Question 16: Global warming is essentially an enhanced greenhouse effect caused by increased greenhouse gas emissions from human activities.

Question 17: 1 degree Celsius

Question 18: 16

Question 19: As temperatures rise, more methane is released from sources like melting permafrost, which further increases warming.

Question 20: The process where thawing permafrost releases previously frozen organic matter, which decomposes and releases carbon dioxide and methane, further contributing to global warming.

Question 21: Ice core samples provide a historical record of past climate conditions, including temperature, greenhouse gas concentrations, and other environmental factors.

Question 22: Reducing livestock emissions, capturing methane from landfills and wastewater treatment plants, and reducing leaks from natural gas infrastructure.
