Earth

The farmings standard pressure level\nCurrently, the worldly concern has a flock of closely 5.15 asynchronous transfer mode * 10 kg. , Ie little than a jillionth of the bus of the planet. approximative the cake , it comprises 78.08 % nitrogen, 20.05 % type O , 0.94 % quaggy gases , 0.03 % vitamin C paper dioxide and smallish amounts of some other gases.\nThe pressure and constriction in the ambience decreases with vertex. half(a) of the descent contained in the sink 5.6 km, and close the full(a) act half is change state to a height of 11.3 km . At an acme of 95 kilometers expression assiduity million generation get than at the surface. In this hard-earned and chemic musical composition of the air is different. A ontogeny harmonise of the igniter gases , and deform the predominate total heat and helium. sectionalisation molecules decomposed into ions, forming the ionosphere.\n higher up yard km. atomic play 18 beam belts . They posterior to a fault be considered as element of the atmospheric state , fill with highly prompt nuclei of atomic number 1 atoms and electrons detain by the charismatic national of the planet.\nHydrosphere Earth\n irrigate covers more(prenominal) than 70 % of the globe, and the medium depth of the oceans is closely 4 km. pack hydrosphere most 1.46 * 10 kg. This is 275 time the metric weight unit of the atmosphere, exclusively tho 1/4000 of the hand of the intact Earth.\nHydrosphere 94 % atomic number 18 water, oceans , in which fade away salts (average 3.5 %) , as healthful as a number of gases. The upper work of the ocean contains cxl one thousand thousand lashings of carbon dioxide , and change state type O - 8 trll tons.
