The Questions:
A. In looking at your graphs for Water and Overlake Air Temperature, what do you see? Are the graphs consistent with each other? Are there any unusual years? Which lake has the highest temperatures, which lake has the lowest? What are some factors that might affect water temperature?
B. In looking at your graph of the differences between the Water and Overlake Air Temperature, what do you see? Are the differences consistent lake to lake? Which lake has the highest difference? Which appears to have the least difference? Why do you think this might occur? Is there an anomaly in the data? Which lake has this anomaly if there is one? Is there something in the previous graphs that might have alerted you to this if there is one?
C. In looking at your graph for Evaporation, what do you see? Which lake had the highest amount of Evaporation? Which had the least? Would you expect this given the temperature data that you graphed? What might be some other factors, other than temperature that might cause this difference?
