Which   of   the   following   characteristics   is associated with maritime climates? 1. Minimal cloudiness 2. Little precipitation 3. Small diurnal temperature range 4. Large annual temperature range 6-24. The amount of radiant energy absorbed by the sea   when   the   Sun   is   directly   overhead   is approximately what percent? 1. 3 2. 6 3. 25 4. 91 6-25. Which,  if  any,  of  the  following  statements  is characteristic  of  the  interchange  of  radiation between Earth’s oceans and the atmosphere? 1. The  interchange  is  a  short-wave  radiation exchange 2. The interchange is primarily dependent on the sea-surface temperature and the amount of water vapor in the atmosphere 3. The interchange is solely dependent on the time of day and season of the year 4. None of the above apply 6-26. Convective   activity   is   most   likely   to   occur when 1. warm air moves over cold ocean waters 2. cold air moves over warm ocean waters 3. warm air moves over warm ocean waters 4. cold air moves over cold ocean waters 6-27. When is evaporation of Earth’s surface waters most intense? 1. When the vapor pressure of the atmosphere is greater than that of the surface water 2. When the vapor pressure of the atmosphere and the surface water coincide 3. When  the  vapor  pressure  of  the  surface water  exceeds  the  vapor  pressure  of  the atmosphere 4. When   the   air   temperature   exceeds   the water temperature 6-28. Oceans are an abundant source of moisture, but precipitation   occurs   much   more   frequently over land than over the oceans for which of the following reasons? 1. Orographic influences 2. Stronger temperature contrasts 3. Greater vertical mixing 4. All of the above 6-29. Atmospheric  soundings  show  that  a  layer  of moist air exists in the tropics. During favorable weather, what is the mean depth of this layer? 1. 2,000 to 3,000 feet 2. 3,000 to 5,000 feet 3. 5,000 to 8,000 feet 4. 5,000 to 12,000 feet 6-30.
