1-25. For meteorological purposes, Earth’s atmosphere is classified into zones or layers by its thermal structure. Working upward through the atmosphere, which of the following lists of zones is correct in its vertical order? 1. Troposphere, tropopause, mesosphere, mesopause 2. Troposphere,    stratosphere,    mesosphere, exosphere 3. Mesosphere,   mesopause,   thermosphere, exosphere 4. Stratosphere, mesosphere, exosphere, thermosphere 1-26. On some atmospheric soundings, it is sometimes  possible  to  have  more  than  one tropopause recorded. 1. True 2. False 1-27. The rise in temperature in the upper portion of the stratosphere is attributed to 1. the absence of water vapor 2. excessive amounts of water vapor 3. the presence of ozone 4. its relative closeness to the Sun 1-28. Which of the following zones marks the outer limit of Earth’s atmosphere? 1. Mesosphere 2. Troposphere 3. Stratosphere 4. Exosphere 1-29. Which  of  the  following  zones  is  an  electrical classification? 1. Exosphere 2. Mesosphere 3. Troposphere 4. Thermosphere 1-30. At night, the Earth’s surface radiates some of the heat it gains during the day, and it cools. by what  process  does  the  layer  of  air  in  contact with the Earth’s surface cool? 1. Radiation 2. Conduction 3. Convection 4. Advection 1-31. The  specific  heat  of  water  is  1.  What  does  1 represent? 1. The temperature of the water 2. The    calorie    requirement    to    raise    the temperature of 1 gram of water 1° Celsius 3. The  weight  of  the  substance  used  in  the ratio 4. The time requirement (in minutes) to raise the  temperature  of  1  gram  of  water  1° Celsius 1-32. The horizontal transport of heat is known as 1. radiation 2. conduction 3. convection 4. advection 1-33. Earth’s atmosphere is capable of holding more water  vapor  (water  in  its  gaseous  state)  at which of the following latitudes? 1. 5°N 2. 30°N 3. 60°N 4. 80°N 1-34. Which of the following statements concerning saturation is correct? 1. Water vapor does not exist in a volume of the atmosphere that is saturated 2. To   saturate   air   at   the   Earth’s   surface requires  less  water  vapor  per  unit  mass than at 500 mb. 3. The  degree  of  saturation  is  dependent  on pressure 4. If   equal   amounts   of   water   vapor   are injected into the atmosphere, saturation is more likely to occur in polar regions before it occurs in equatorial regions 1-35. Which of the following occurrences will result in the condensation of water vapor? 1. Air moved over a colder surface 2. Air lifted mechanically 3. Air-cooled    by    the    radiational    cooling process 4. Each of the above 3
