PHYSICAL GEOGRAPHY PRACTICE QUIZ:
ATMOSPHERIC MOISTURE

- A
- 100%
- B
- 40%
- C
- 25%
- D
- 80%
- E
- Not enough information given to determine the answer
2. High-altitude, wispy clouds composed of ice crystals may precede a cold front. What type of clouds are these?
3. Puffy white clouds in lines or groups at middle altitudes in the sky are what type of clouds?
4. Low rainclouds that form layers or sheets covering the whole sky are what type of clouds?
5. Thunderheads, rising to great heights and accompanied by thunder and lightning, are what type of clouds?
6. If a parcel of air rises, and the amount of water vapor in the air does not change, what will most likely happen to the relative humidity?
- A
- Increase
- B
- Decrease
- C
- Remain the same
- D
- Not enough information given to determine the answer
7. Rainfall caused by air rising up the slopes of mountains is what type of rainfall?
8. Worldwide, where would you expect the least amount of precipitation?
- A
- Along the equator in the Intertropical Convergence Zone
- B
- On the west coasts of continents at about 50 degrees north and south
