  3. Answer #1 • D. Relative Humidity

  4. Question #2 • Name the 3 main processes below.

  5. Answer #2 • Evaporation, condensation, precipitation.

  6. Question #3 • What is the process by which trees and plants lose moisture through evaporation?

  8. Question #4 • What is all over this guy’s head (not starting with the letter “s”), and how does this help regulate his body temperature?

  9. Answer #4 • This is perspiration and it helps to keep his body cool by evaporation.

  10. Question #5 • If a cubic meter of air in San Diego can hold 400 grams of water vapor at 70º F, then what is the relative humidity at this temperature if the air is holding 80 grams of water vapor?

  11. Answer #5 • 20%. Since the air is holding 80/400 or 1/5 of the water vapor it can hold, it’s relative humidity is 1/5 or 20%.

  12. Question #6 • The difference in temperature between the wet bulb and the dry bulb on a psychrometer are very close in temperature. What does this tell us about the weather?

  13. Answer #6 • It tells us that the relative humidity is high since there was little evaporation in the wet bulb, and the temperature didn’t change much as a result.

  14. Question #7 • If there is a very large difference in the temperature readings between the wet bulb and the dry bulb thermometers on a psychrometer, what does this tell you about the relative humidity?

  15. Answer #7 • It tells you that the relative humidity is very low.

  16. Question #8 • Spell the name of the instrument that is used to measure relative humidity.

  17. Answer #8 • P-S-Y-C-H-R-O-M-E-T-E-R

  29. Answer #13

  30. Question #14 • When the steamship Home sank during a hurricane off Ocracoke, North Carolina in 1837, what law did the U.S. Congress pass that related to this?

  31. Answer #14 They passed a law requiring every sea-going ship to carry a life preserver for every passenger.

  33. Answer #15 • Let it SNOW!

  34. Question #16 • Which of the following states are not in tornado alley? Texas, Oklahoma, Mississippi, Kansas, Nebraska, California.

  35. Answer #16 Mississippi California

  36. Question #17 • The reason why clouds form high in the air is: • The higher you go, the wetter it will always be. • Clouds can’t form near the ground. • Most air condenses higher in the troposphere. • Moist air evaporates with altitude.

  37. Answer #17 • Warm moist air rises, cools and condenses.

  38. Question #18 • Cirrus means which of the following? • Of or pertaining to a circus. • Frizzy hair. • Puffy hair • Serious. • A curl of hair.

  39. Answer #18

  40. Question #19 • What type of cloud is this?

  41. Answer #19 • Cumulonimbus

  42. 20-30 are True and False. • For True, just say “True”. For False, say “False”, then explain why the statement is false.

  43. Question #20 • Since alto means “high”, altostratus and altocumulus clouds are the highest of all clouds.

  44. Answer #20 • False. Although “alto” does mean high, altostratus and altocumulus clouds are only mid-level clouds. Cumulonimbus and any of the cirrus clouds are higher.

  45. Question #21 • Clouds are categorized by their shape and their altitude.

  46. Answer #21 • True

  47. Question #22 • You see lightning and you immediately start counting seconds. You count to 15 seconds. The lightning must have been 5 miles away since thunder travels a mile for every 3 seconds.

  48. Answer #22 • False. The speed of sound travels about 5 seconds for every mile so the lightning must have been 3 miles away.

  49. Question #23 • Fog occurs when clouds start sinking from higher in the atmosphere to settle on the ground.
