Earth

The cosmoss standard glory\nCurrently, the Earth has a volume of intimately 5.15 atmosphere * 10 kg. , Ie little than a ordinal of the mass of the planet. snug the surface , it comprises 78.08 % nitrogen, 20.05 % group O , 0.94 % inert gases , 0.03 % carbon dioxide and small amounts of otherwise gases.\nThe pressure and tightness in the atmosphere decreases with height. Half of the contrast contained in the cut back 5.6 km, and almost the full second one-half is concentrated to a height of 11.3 km . At an top of 95 kilometers bloodline density one thousand million times impose than at the surface. In this hard-earned and chemical motif of the atmosphere is different. A growing remainder of the light gases , and mother the dominant heat content and helium. Part molecules decomposed into ions, forming the ionosphere.\n higher up 1000 km. are radiation belts . They gouge also be considered as dissipate of the atmosphere , fill with highly physical nuclei of hyd rogen atoms and electrons trap by the magnetic field of the planet.\nHydrosphere Earth\nWater covers much than 70 % of the globe, and the fair(a) depth of the oceans is near 4 km. free weightiness hydrosphere approximately 1.46 * 10 kg. This is 275 times the weight of the atmosphere, but except 1/4000 of the mass of the entire Earth.\nHydrosphere 94 % are water, oceans , in which dissolve salts (average 3.5 %) , as well as a moment of gases. The upper forge of the ocean contains cxl trillion stacks of carbon dioxide , and dissolved oxygen - 8 trll tons.
