Identify whether the statement is true or false, and why? "Global sea levels have not changed in the past, the fact that they are rising now could be very dangerous." A. False, it should read "Global sea levels have risen very quickly in the past, so the change today could be very dangerous, but is not caused by humans." B. True C. False, it should read "Global sea levels have changed in the past, the reason they are dangerous now is because the change is occurring very fast." D. False, it should read "Global sea levels have changed in the past, but they are not changing today."
Which of the following is evidence of climate change? A. Rise in global sea level. B. Burning fossil fuels releases sulfates. C. Decrease in extinction rates. D. Increasing salt levels in the Arctic ocean.
The best definition of a proxy record is: A. Scientific measurements made using proximal distances between data points. B. Scientific measurements that are indirect and not recorded with instruments. C. Scientific measurements that contain data points that are average approximations of specific measurements. D. Scientific measurements that use one set of data to represent another set of data in a calculation.
Which of the following natural processes can remove carbon dioxide from the air? A. Nitrogen cycle B. Photosynthesis C. Water cycle D. Respiration
Which of the following could be a benefit of climate change? A. There will be decreased amounts of snowfall. B. Flooding would increase, bringing water to areas in drought. C. Some crops would be able to grow further north than normal. D. Bird migration will be altered, changing their nesting patterns.
How are atmospheric carbon dioxide levels and average global temperature related? A. There is a positive relationship. B. Temperature is the clear cause of carbon dioxide levels. C. They are not related. D. There is a negative correlation.
How does deforestation (cutting trees down), affect carbon dioxide levels in the atmosphere? A. When they are cut down they no longer absorb carbon dioxide, increasing the levelshin the atmosphere. B. Trees have no effect on carbon dioxide in the air. C. When each tree is cut down, they release a large burst of carbon dioxide, increasing the levels in the atmosphere. D. When they are out down they no longer produce carbon dioxide, decreasing the levels in the atmosphere.
Why is it important to have funding for alternative energy sources, such as solar, wind, or biofuel? A. All of these B. Alternative energy sources will run out soon, so we need to make use of them while we can. C. They create little or no carbon dioxide. D. They will make far greater profits than fossil fuels.
