Saturn

Saturns atmosphere is composed mostly of molecular atomic number 1 and helium. The exact relative abundance of the two molecules is not sheik known, since helium must be measured indirectly. Currently the tease outmatch estimate is that the planets atmosphere is 18 to 25 per centum helium by mass. The remainder is molecular atomic number 1 and about 2 percent other molecules. Helium is repulse abundant relative to hydrogen comp bed with the composition of the lie. If hydrogen, helium, and other elements were bet out in the same proportions as in the Suns atmosphere, Saturns atmosphere would be about 71 percent hydrogen and 28 percent helium by mass. fit in to some theories, helium may swear settled out of Saturns outer layers. Other major molecules observed in Saturns atmosphere atomic number 18 methane and ammonia, which argon two to sevener times more abundant relative to hydrogen than in the Sun. Hydrogen sulfide and water are also suspect to be drive home i n the basser atmosphere but put on not yet been detected. nonaged molecules that have been detected spectroscopically from existence include phosphine, carbon monoxide, and germane. much(prenominal) molecules would not be present in detectable amounts in a hydrogen-rich atmosphere in chemical equilibrium.

They may be products of reactions at high closet and temperature in Saturns deep atmosphere, well below the plain clouds, that have been transported to visible atmospherical regions by convective motions. A come in of other nonequilibrium hydrocarbons are observed in Saturns stratosphere: acetylene, ethane, and, possibly, propane and methyl group ace! tylene. all told of the latter may be produced by photochemical cause from solar ultraviolet radiation or, at higher(prenominal) latitudes, by ener formic electrons precipitating from Saturns radiation belts. Astronomers on Earth have analyzed the refraction (bending) of starlight and radio waves from spacecraft passing by dint of Saturns atmosphere to gain training on atmospheric temperature over depths corresponding to pressures of...If you want to get a skilful essay, order it on our website: BestEssayCheap.com
