Ionosphere: evolution of the atmosphere, degassing atmosphere. Figure 3. 3; table 3. 1 (atmospheric criteria: composition of atmosphere, heterosphere (layered, outer atmosphere, 80 km (50 mi) outward, to thermopause, gases layered by weight/gravity- not evenly mixed, < . 001% of atmosphere mass, homosphere (mixed) --normal lapse rate- average cooling at rate of 6. 4 c/km (3. 5 f/1000 ft) --travel up a mountain or airplane/balloon- temperature decrease. --figure 3. 6: tropopause, 57 c (-70 f, altitude varies with spatially and with the season, atmospheric function. Inert- does not react with other elements e. g. , noble gases and n2 gas: noble gases- (he, ar, kr, xe, rn) inert gases, sources are radioactive decay and formation of the solar system or supernova, protective atmosphere, ozone (o3)
