Clouds permitting, the quiz will start with a cloud quiz.

  1. ____________________ Cloud type?
  2. ____________________ Cloud type?
  3. ____________________ Cloud type?
  4. ____________________ Cloud type?
  5. ____________________ About how many years are there between ice ages on the planet Earth?
  6. Based on evidence from the Cretaceous period and the Mauna Loa carbon dioxide curve, what is the effect of excess carbon dioxide in the atmosphere (CO2)?
  7. _____________________________ What precipitation process produces the typical rain on Pohnpei?
  8. _____________________________ What precipitation process produces rain, lightning, and thunder?
  9. _____________________________ What precipitation process produces rain as a result of wind rising up the windward slope of mountains?
  10. ____________________ What is the temperature of the dry bulb thermometer?
  11. ____________________ What is the temperature of the wet bulb thermometer?
  12. ____________________ What is the wet bulb depression today?
  13. ____________________ Determine the relative humidity today. [Use your text]
  14. ____________________ Determine the heat index today. [Use your text]
  15. _________________________ Determine the risk level for exercise today. [Use your text]
  16. ѵ = _______________ During ten seconds a clapper claps 25 times. The echo flight distance is measured as being 140 meters. Based on this data, what is the speed of sound ѵ?
  17. d = ________________ If you hear thunder six seconds after you see a lightning flash, how far away is the storm in kilometers d? Use the velocity calculated in the problem above to make this calculation.
  18. A RipStik was ridden across a wet cloth towel soaked in water with blue food color. The RipStik was then swizzled across a large sheet of presentation paper as seen below.
    RipStik swizzle sine wave 5 cm 50 cm RipStik rider

    λ = _______________ Determine the wavelength λ of the RipStik swizzle wave.
  19. a = _______________ Determine the amplitude a of the RipStik swizzle wave.
  20. ѵ = _______________ The RipStik traveled 200 centimeters in 2 seconds. Calculate the linear velocity ѵ for the RipStik.
  21. f = _______________ For a RipStik, the linear velocity is equal to the swizzle wave velocity. Use the velocity above and the wavelength to calculate the swizzle wave frequency f.
  22. Plot the data on the graph.

  23. Draw a linear best fit line through the data points on the graph.
  24. ______________ Calculate the slope of the linear best fit line. The slope is the experimental index of refraction for water.
  25. ______________ The above material is reported to have a theoretic index of refraction of 1.3. What is the percentage error for the slope you calculated based against a theoretic value of 1.3?
