| Question | Answer |
| Define Insolation: | Incoming Solar Radiation. |
| State the two general ways that insolation can vary. | 1) Intensity (strength) and 2) duration. |
| Why are the Tropics always hot? | High angle of insolation, high intensity, hot. |
| Name the maximum angle of insolation. | Zenith, 90 degrees, directly over head. Minimal refraction or reflection of insolation as light passes through less atmosphere. |
| Why are the Poles always cold? | Low angle of insolation, low intensity, cold. Increased refraction and reflection of insolation as light must pass through more atmosphere. |
| Name the minimum angle of insolation. | Zero degrees, no light. |
| High angle the light is concentrated, strong. Low angle is what? | Diffuse , weak, spread out over an area. |
| If angle of insolation is 90 degrees at 10 degrees North, what is the angle of insolation at the Equator or 20 degrees North? | 80 Degrees is the angle of insolation as angle decreases one degree for every one degree north or south that one travels away from the solar zenith. |
| How does change in Latitude effect intensity of insolation? | Latitude where Sun is at zenith, angle of insolation = 90 degrees has max energy. Polar region with 24 hours of night has minimal energy receipt. |
| Explain how seasonal variation effects energy receipt. | Summer entails high angle of insolation, hot. Winter calls for low angle, low intensity, cold. |
| How does time of day effect energy receipt? | Sunrise & sunset = low angle, low intensity, cold. Solar noon = high angle, high intensity, hot. |
| Describe duration of insolation. | How long the Sun is out. |
| Name the dates where duration of insolation is maximum, and minimum, here in NYS. | June 21 max., December 21 min. 15 hrs day/9 hrs night, vs 9/15 |
| Latitude and Season together impact which two insolation variables? | Angle and Duration of Insolation. |
| When will you be enjoying greater intensity of insolation, when you have a long shadow or a short shadow? | Short shadow. High angle of insolation, high intensity, hot. |
| What time will the air temperature be hottest each day if there are no overriding factors? | Solar noon plus two (2) hours. |
| What month of the year is it hottest or coldest? | The Solstice plus six (6) weeks. Or, August 1st for hottest, February 1st for coldest. |
| Why the six week time temperature lag? | Earth the rock takes time to absorb and then re-radiate EM radiation. |
| Is average air temp increasing or decreasing during a solar energy surplus? | Increasing. More energy in, less out. |
| Is average air temp increasing or decreasing during a solar energy deficit? | Decreasing. More energy out, less in. |
| Can you complete pages 110 and 111, all multiple choice questions, 11-31? | Complete and remit correct answers to the instructor!! |
