Question #1
Imagine that something kills off all of the white daisies and there are only black daisies left growing on Daisyworld. What will happen to the global temperature and daisy count on Daisyworld?
A.   The global temperature will decrease, and the black daisy count will stay exactly the same.
B.   The global temperature will rise, and the black daisies eventually die off.
C.   The global temperature will rise, and the black daisy count will rise indefinitely.
D.   The global temperature will decreases, and the black daisies will eventually die off.
Question #2
Now imagine that there are only white daisies growing on Daisyworld. What will happen to the global temperature and daisy count on Daisyworld?
A.   The global temperature and daisy population will stay exactly the same throughout time.
B.   The global temperature will decrease, and then the white daisies will die off. Once they are gone, temperature rises.
C.   The global temperature will increase, and the daisies will continue to grow in population.
Question #3
What is the albedo of a perfect mirror?
A.   100%
B.   0%
C.   1/3
D.   50%
Question #4
What is the albedo of a perfectly black surface?
A.   50%
B.   1/7
C.   100%
D.   0%
Question #5
On Daisyworld, an equal combination of black and white daisies creates what type of feedback loop?
A.   Positive feedback loop
B.   Neutral feedback loop
C.   It doesn't create a feedback loop
D.   Negative feedback loop
Question #6
When solar radiation warms the earth and causes water to evaporate, which in turn creates clouds, which in turn cool down the earth, this is an example of:
A.   a positive feedback loop
B.   the carbon cycle
C.   an environment
D.   a negative feedback loop
Question #7
When solar radiation melts glaciers on the earth's surface, this causes greenhouse gases to be released, which then trap more solar radiation and leads to more glacial melt, which releases more greenhouse gases (and on and on...). This is an example of:
A.   a positive feedback loop
B.   glaciation
C.   a negative feedback loop
