I need help on this lab http://phet.colorado.edu/en/simulation/greenhouse

6) Explain why this happens. 7) In order to better insulate your house from a radiation standpoint, would it be better to use single- , double, or triple-pained windows? 8) Before proceeding to the earth, we can treat earth's atmosphere as a glass pane. Predict how what you have discovered regarding greenhouses might apply to the earth and its atmosphere. Part ll: The Earth Simulation - Select the \"Greenhouse Effect\" tab. Uncheck the \"View all photons\" box. 9) Which greenhouse gases are considered by the simulation? 10) Which time period do the default conditions represent? - The thermometer represents the average global temperature. Greenhouse Temperature Path of Sunlight Path/Behavior of Is this more similar Gas Photons Infared Photons to \"without glass Simulation (Start/End/Direction of (Start/End/Direction/ panes" or \"with Travel?) Change in Direction?) glass panes\"? 11) Considering the behavior of the infared photons, why does the temperature drop so much without greenhouse gases? 12) Considering the behavior of the infared photons, why does the temperature increase so much with lots of greenhouse gases? Experiment with other periods in earth's history. Rank them from lowest temperature to highest temperature. - Does adding clouds increase or decrease the temperature
