Question 8: A stable air mass is most likely to have which characteristic?

Answer:

smooth air.

Question 9: The suffix" nimbus" used in naming clouds, means

Answer:

a rain cloud.

Question 10: Moist, stable air flowing upslope can be expected to

Answer:

produce stratus type clouds.Question 11: Convective circulation patterns associated with sea breezes are caused by

Answer:

Cool, dense air moving inland from over the water Question 12: What are the processes by which moisture is added to unsaturated air?

Answer:

Evaporation and sublimation.

Question 13: Which conditions result in the formation of frost?

Answer:

The temperature of the collecting surface is at or below the dewpoint of the adjacent air and the dewpont is below freezing.
