1-12. The     temperate     zone     in     the     Southern Hemisphere  receives  sunshine  all  year,  but receives more sunshine when winter is being experienced in the Northern Hemisphere. 1. True 2. False 1-13. If  the  Sun’s  radiation  (Earth’s  incoming  solar radiation) was not dispersed or filtered, Earth would  eventually  become  too  hot  for  life  to exist   as   we   now   know   it. Which   of   the following   factors   plays   the   major   role   in dispersing Earth’s insolation? 1. Scattering 2. Earth’s inclination 3. Earth’s rotation 4. Reflection 1-14.

Scattering capability 3. Absorption capability 4. Reflective capability 1-15. What   percentage   of   Earth’s   insolation   is absorbed by land and water? 1. 13 % 2. 36 % 3. 43 % 4. 51 % 1-16. Through its atmosphere’s ability to absorb and lose heat, Earth enjoys an average temperature of 15°C/59°F. If it failed to absorb short-wave radiation   and   radiate   long-wave   radiation, Earth’s average temperature would be 1. -04°F 2. -04°C 3. -35°F 4. -35°C 1-17. The  poles  receive  far  less  incident  radiation than the equator. What is the effect on a polar air column in relation to a column of air over the equator? 1. It is more shallow and lighter 2. It is more shallow and heavier 3. It is thicker and heavier 4. It is thicker and lighter 1-18. Which  of  the  following  sea  level  pressure(s) is/are  the  standard  used  by  the  International Civil Aeronautical Organization? 1. 1013.25 millibars 2. 29.92 inches of mercury 3. 14.7 lbs. per square inch 4.
