Unformatted text preview: CA, one on December 16, 1998 and one on May 22, 1999. Question (1)(c). Describe the pattern of insolation over the full day recorded on December 16, 1998. Repeat for May 22, 1999. (Don’t compare the two plots—just describe each.) 4 As evidence to support your response to the next question, use the observations of insolation and temperature at Hanford, CA that you described in Questions (1)(b) and (1)(c). Question (1)(d). Evaluate the following statement: “In the sense that temperature increases when insolation increases, reaches a high (maximum) when insolation does, decreases when insolation decreases, and reaches a low (minimum) when insolation does, insolation ‘explains’ the daily temperature cycle very well.” 5 Refer again to the two graphs that each show a single plot of insolation recorded on a horizontal surface at the earth's surface at Hanford, CA, on December 16, 1998 and May 22, 1999, respectively. One difference that we can see between these plots is that for every hour that the sun was up on December 16, 1998, the sun was less intense than it was on May 22, 1999 at the same hours. Suppose that someone proposes a possible explanation for this difference, and two other people each propose an alternative explanation. (In fact there are many potential explanations, though most aren’t very likely or even plausible.) Suppose that the three proposed explanations are: The difference in observed solar intensity 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 (1)(e). 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...
