O-Oxygen N2- molecular nitrogen Argon (Ar)- 97%-inert gas (don't react at all, single atoms) Carbon- 94% Atmospheric composition: -molecular oxygen and nitrogen are major components-99% of the remaining 3%, 97%, is the inert gas argon of the remaining 7%, 93% is carbon dioxide all remaining gases- about 2 parts in 100,000 are known as trace species these gases control the chemistry of the troposphere ________ lec 3 -cold front severe weather radiation is parallel something holding up- pushing down on mercury weight of the air "pressure" barometer on mountain -weight of air less-pressure less with altitude pressure0wight of air above us air inside body -counteracts pressure above our head measure pressure by height of mercury BAR-unit kg/m -close to 1 atmosphere drop in temp with altitude put energy into atmosphere-heat source (ozone)-UV liter, absorbs energy temp goes up with altitude very stable, layered (strata) thermosphere goes up become of solar heating and less density -dont need much mass
