We tell the world is being lapped by aerosphere, below the action of earthly gravitation, a large number of gas gather in the earth all round, about 2000 kilometre come 3000 kilometre are thick, formed the aerosphere with thousands of thick kilometre, undertake protective to the earth. According to scientists estimation, air mass makes an appointment with 6E15 tons, 1/1000000 be earthly total mass almost. Nitrogen of atmosphere component content 78% , oxygen 21% , argon 0.93% , carbon dioxide 0.03% , neon 0.0008% , still have hydrosphere in addition, dust, enrage sol and grain of large size in suspension. Because be below the protective action of earthly magnetic field, make aerosphere reachs the universe in sun wind the action blowing corrode of high-energy ray is able to save, on the other hand aerosphere can protect our earth live thing again, avoid suffer ab extra aerolite, shooting star, sun ray the descent that wait.
Although aerosphere is right,tellurian biology and mankind are crucial partially, if the earth does not have aerosphere, all biology on the earth can disappear. But earthly gravitation and aerosphere do not have any relations, if the earth does not have gravitation aerosphere also not Fu exists. The existence of gravitation is the quality with the earth about, quality large gravitational force is large, force of quality introductory note is small, so gravitation is decided by the quality place of the object, with have aerosphere not to have any relations, already quality has gravitational force, have gravitational force all the same without aerosphere earth.
