For each of these three possible explanations, cite a piece of evidence that either supports or contradicts the explanation, and explain how so. (As evidence, use facts and/or ideas from Page 1 of this lab, the concept map about insolation at the earth’s surface that we constructed in class, the Hanford meteograms, or data from Lab #3, Part I, as appropriate.) 8 On the same two graphs (showing insolation at the top of the atmosphere on December 16, 1998 and on May 22, 1999), refer now to the plots of one- hour average insolation on a horizontal surface. One difference that we can see between these two plots is that for every daylight hour on December 16, 1998, the sun was less intense (on a horizontal surface) than it was at the same hours on May 22, 1999. Suppose that someone proposes a possible explanation for this difference, and two other people each propose an alternative explanation. Suppose that the three proposed explanations are: The difference in solar intensity between the two days (on a horizontal surface at the top of the atmosphere) was due to: 1. the difference in distance between the earth and the sun on the two days 2. the difference in sun angle between the two days, at each daylight hour 3. the difference in atmospheric conditions (composition) between the two days Question (2)(c). For each of these three possible explanations, cite at least one piece of evidence that either supports or contradicts the explanation, and explain how so. (As evidence, use facts and/or ideas from Page 1 of this lab, the concept map about insolation at the earth’s surface that we...
