Temperature Choose your answers to problems 2, 3, 5, 6, and 8 from the regions of the atmosphere listed below: Regions of the atmosphere: exosphere, mesosphere, stratosphere, thermosphere, troposphere 02. If you want to study weather, which region of the atmosphere would you study? 03. If you want to study the ozone layer, which region of the atmosphere would you study? 04. If a sample of air is predominately oxygen, did it most likely come from the homosphere or the heterosphere? 05. Which regions of the atmosphere are in the homosphere? 06. Which regions of the atmosphere are in the heterosphere? 07. A barometer develops a leak in the column which is supposed to be free of air. As air seeps into the column, what will happen to the height of the liquid in that column? 08. In what region(s) of the homosphere does temperature increase with increasing altitude? 09. Why is the "ozone hole" a seasonal phenomenon that exists only at the South Pole? 10. We all know that ice melts because of heat. Why is it correct to say that ice also freezes because of heat? 11. If you were able to measure the speed of the molecules in the air while you were traveling up through the troposphere, would the speed of the molecules increase, decrease, or stay the same as your altitude increased?
