1 .		The ratio of the actual amount of water in the atmosphere to the maximum possible at that temperature is the    absolute humidity.   dew point temperature.   specific humidity.   relative humidity.   sensible temperature.
2 .		When water changes phase, what always happens?    It rains.   It snows.   A cloud is formed.   Latent heat heat is consumed or released.   Some form of precipitation occurs.
3 .		Which of the following statements is true?    Condensation absorbs heat and thus warms the atmosphere.   Evaporation absorbs heat and thus warms the atmosphere.   Condensation releases heat and thus cools the atmosphere.   Evaporation releases heat and thus cools the atmosphere.   Evaporation absorbs heat and thus cools the atmosphere.
4 .		The saturated adiabatic lapse rate is less than the adiabatic lapse rate because    they are the same.   evaporation warms the dry adiabatic lapse rate.   moist air is always warmer than dry air.   condensation releases latent heat.   condensation absorbs latent heat.
5 .		Identify this cloud type. [Hint]   cumulonimbus   cirrus   cumulus   stratus   altocumulus
6 .		Unstable air is best associated with    convective lifting.   orographic lifting.   a temperature inversion.   very low surface temperatures.   descending air.
7 .		Which of the following is true of the collision-coalscence process?    Water droplets evaporate.   Ice crystals grow at the expense of water droplets.   Water droplets merge and grow in size.   It is the same as the Bergeron process.   It causes most precipitation in middle and high latitudes.
8 .		An air parcel experiences a buoyant force when its    density is greater than the surrounding air.   temperature is greater than the surrounding air.   water content is greater than the surrounding air.   pressure is greater than the surrounding air.   dew point temperature is higher than the surrounding air.
9 .		Low precipitation amounts are typical of    equatorial latitudes.   the ITCZ.   the summer monsoon in India.   polar latitudes.   mid-latitude west coast locations.
10 .		Why might condensation occur below 100% relative humidity?    droplet curvature effects   hygroscopic nuclei present   ice absent, even in cold clouds   latent heat effects   none of the above
11 .		If water droplets and ice crystals are both present in the same cloud, [Hint]   the ice crystals will shrink while the drops grow.   the ice crystals will grow while the drops shrink.   both will grow if the temperature is at the dew point.   the ice crystals will behave independently of one another.   neither the droplets nor the crystals will grow.
12 .		When raindrops fall through a shallow layer of sub-freezing air near the surface, what type of precipitation occurs?    snow   hail   drizzle   rain   glaze
