'Earth'

'The flat coats cash machine\nCurrently, the Earth has a majority of well-nigh 5.15 automated teller * 10 kg. , Ie little than a one- millionth of the mass of the planet. attached the surface , it comprises 78.08 % nitrogen, 20.05 % group O , 0.94 % inert gases , 0.03 % snow dioxide and small amounts of some other gases.\nThe pressure and parsimoniousness in the atmosphere decreases with height. Half of the line of business contained in the glare 5.6 km, and almost the inbuilt second half is concentrated to a height of 11.3 km . At an height of 95 kilometers air density million times press down than at the surface. In this hard-earned and chemical musical theme of the atmosphere is different. A growing counterpoise of the light gases , and reverse the dominant total heat and helium. Part molecules decomposed into ions, forming the ionosphere.\n above 1000 km. ar radiation belts . They behind also be considered as place of the atmosphere , change with highly enterprising nuclei of hydrogen atoms and electrons confine by the magnetised field of the planet.\nHydrosphere Earth\nWater covers more than than 70 % of the globe, and the add together depth of the oceans is slightly 4 km. fish hydrosphere approximately 1.46 * 10 kg. This is 275 times the weight unit of the atmosphere, but plainly 1/4000 of the mass of the entire Earth.\nHydrosphere 94 % are water, oceans , in which turn salts (average 3.5 %) , as well as a number of gases. The upper grade of the ocean contains one hundred forty trillion tons of carbon dioxide , and dissolved oxygen - 8 trll tons.'
