Document Summary
***think of it as peach fuzz on a peach*** Climate: climate 30 years of information averaged out long term, weather stuff going on right now short term. We weren"t here: but we know plants and photosynthesis [plants take in carbon dioxide and give off oxygen] had something to do with it. Atmospheric profile: we differentiate the layer of the atmosphere by boundaries. Air pressure: earth"s atmosphere (atm) exerts its weight, pressing downward due to gravity, air molecules create air pressure through motion, size, and number. Pressure is exerted on all surfaces in contact with air: the weight (or force) of the atm, or air pressure, pushes in on all of us. Atmospheric density: density = mass/volume, decreases with height due to the effect of gravity, at sea level, the average pressure is 1013. 25 millibar(mb) or. Atmospheric conditions: 2 broad regions, homosphere lots of nitrogen, heterosphere.
