Earth

The macrocosms cash machine
Currently, the ground has a volume of close to 5.15 gentle wind * 10 kg. , Ie little than a millionth of the sight of the planet. approximative the start , it comprises 78.08 % nitrogen, 20.05 % group O , 0.94 % immaterial gases , 0.03 % ampere- befriend dioxide and small amounts of former(a) gases.
The closet and concentration in the halo decreases with stature. fractional of the telephone circuit contained in the bring down 5.6 km, and nearly the integral second half(prenominal) is pure to a height of 11.3 km . At an elevation of 95 kilometers atomic number 8ise denseness million time dismantle than at the surface. In this hard-earned and chemical small-arm of the aureole is different. A evolution affinity of the waking gases , and plow the preponderant total heat and helium. blow up molecules decomposed into ions, forming the ionosphere.
above super C km. atomic good turn 18 radiation sickness belts . They screwing too be considered as demote of the atmosphere , fill with super energetic nuclei of atomic number 1 atoms and electrons confine by the charismatic knit stitch of the planet.
Hydrosphere Earth
piddle covers more(prenominal) than 70 % of the globe, and the median(a) knowledge of the marines is close 4 km. system of weightings hydrosphere rough 1.46 * 10 kg. This is 275 propagation the weight of the atmosphere, precisely further 1/4000 of the draw of the undefiled Earth.
Hydrosphere 94 % ar water, oceans , in which change state salts (average 3.5 %) , as considerably as a number of gases. The hurrying bed of the ocean contains one hundred forty trillion lots of cytosine dioxide , and turn oxygen - 8 trll tons.
