Assignment Task: Go to the following website: Koshland Science Museum
You will work your way through this presentation and as you do so look for the information to answer each of the following questions. Some questions may require some additional research in robust information sites like Wikipedia (very reliable for science) to answer. Be a critical consumer of internet information resources.
Question 1: Is the greenhouse effect necessary for life on earth? Why?
Question 2: List 3 gases which contribute to this effect.
Question 3: For the earth to avoid overheating what must happen to most of the radiant energy we receive from the sun?
Question 4: How do greenhouse gases alter this process?
Question 5: What is our current human concern about the greenhouse effect?
Question 6: What was the relationship between release of carbon compounds into the atmosphere and processes removing them from the atmosphere prior to the industrial revolution?
Question 7: Give an example of a naturally occurring process
a. releasing CO2 into the atmosphere.
b. removing CO2 from the atmosphere.
Question 8: Where did the coal, oil and natural gas we are currently use come from?
a. For your answer above state where the carbon in those fossil fuels came from? This is a separate source the answer to question 8 above!
Question 9: For the graph in 'Carbon Cycle' slide 4; provide the change in atmospheric CO2 concentrations for any 20 year interval.
Question 10: Why is it proposed that natural processes cannot account for the change in the atmosphere's energy balance over the past 200 years (roughly the period of widespread fossil fuel use associated with industrialization)?
Question 11: Do some research to identify a natural source of aerosols in the atmosphere and give an example.
Question 12: Considering feedback effects; identify one additional potential ___________ not mentioned in the presentation.
a. negative feedback effect of global atmospheric warming due to rising greenhouse gas concentrations
b. positive feedback effect of global atmospheric warming due to rising greenhouse gas concentrations
