Meteorology Chapter 4 Test Review
1. What causes ice to be less dense than water?
2. At which temperature is water most dense?
3. What is it called when a molecule of water
vapor slows down into a liquid state?
4. What is it called when a molecule of water vapor flash
freezes directly into a solid without becoming a liquid?
5. What is it called when a solid vaporizes directly
into a gas without becoming a liquid first?
6. What percentage is the range of water vapor in the atmosphere?
7. For every 10oC (18oF) increase in temperature, almost _____ times the amount of water vapor is added?
8. Identify the three ways that air temperatures change quickly, causing changes in relative humidity?
9. The uneven heating of the land that will cause pockets of air to be warmed more than the surrounding air
is called.
10. Identify the different ways to saturate a parcel of air.
11. Using Table 4-1, identify how much water vapor must be present in a 1 kilogram parcel of air that is
35oC to be considered saturated.
12. If that same parcel of air (described in question 11) looses 15 grams of water, what temperature must it
be in order to be saturated again?
13. If at 10oC, the parcel of air had 3.5 grams of water vapor present, what would the relative humidity be?
14. What is the Dry Adiabatic Rate?
15. What is the Wet Adiabatic Rate?
16. What numerical representation would represent the idea of Absolute Stability?
17. What numerical representation would represent the idea of Absolute Instability?
18. What is it called when the number of molecules evaporating and condensing are equal?
19. What is the actual amount of water vapor in the air, compared to the amount of water vapor needed for
saturation at that temperature and pressure called?
20. What is the part of the total atmosphere that is made up of water vapor called?
21. What is the temperature to which air must be cooled to reach saturation called?
22. What is the temperature change that occurs even though heat was neither added or subtracted to a
parcel of air called?
23. What is it called when cold, dense air acts as a barrier over which warm, less dense air must rise?
24. What is it called when two warm surface level air masses collide, with neither mass sinking below the
other, but instead both lift high into the atmosphere?
25. What is the height at which a parcel of air becomes saturated and cloud formation begins called?
