1. A large temperature lapse rate would occur in a layer with:

### A) 97 percent

2. About what percent of Earth's water can be found in the oceans?

### D) It expands.

3. Why does a rising air parcel cool off?

### C) condensation

4. Which of the following processes requires the highest release of energy from the water molecules?

### C) 100 percent

6. The amount of water vapor in the air (by volume) usually does not exceed:

### at what elevation will condensation begin? ,B) 1300 meters

7. If air at sea level with a temperature of 27 degrees C is forced up a mountain slope and the air's dew point at the condensation level is 14 degrees C

### B) latent heat is released inside a parcel of rising saturated air.

8. The moist adiabatic rate is different from the dry adiabatic rate because:

### then the atmosphere is said to be: ,C) conditionally stable.

9. If your environmental lapse rate is -7 C/km on a partly cloudy afternoon

### then the atmosphere is said to be: ,B) absolutely stable.

10. If your environmental lapse rate is 17 C/km on a partly cloudy afternoon

### B) colder, more

11. An inversion represents an extremely stable atmosphere because a parcel of air that rises into an inversion will eventually become _______ and ________ dense than the air surrounding it.

### working together, will make the atmosphere the most unstable. ,B) warm the surface and cool the air aloft

12. These two conditions

### B) drops rapidly

13. The atmosphere is most unstable when the temperature of the air _________ with height.

### E) which is rising or sinking.

14. Adiabatic processes are only important for air:

### the temperature decreases because the air has: ,B) lost heat to the colder air at higher altitudes.

15. During the process of adiabatic cooling

### A) The relative humidity at 2:00 p.m. is higher.

17. Assume that the actual vapor content of the air remains constant over the course of the day. How does the relative humidity at 2:00 p.m. probably compare to the relative humidity at 5:00 a.m.?

### C) evaporation of 1 gram of water

18. Which of the following requires the GREATEST RELEASE of latent heat energy into the atmosphere?

### A) Palm Springs will have a higher vapor content than Great Falls. 20. Water vapor constitutes about this much of the atmosphere by volume. A) 0-4 percent

19. The air in Great Falls Montana has a temperature of 5°C and a relative humidity of 50 percent. On the same afternoon the air in Palm Springs California has a temperature of 25°C and a relative humidity of 50 percent. What can be said about the amount of vapor in the air at these two cities?
