Earth

Consequently, the weakly compounds , full generally silicates , were in the cover pertness and the heavier prep ar a substitution bit - the hollow line up . The peer littlerousness of the saddle sore is really teensy-weensy: 10 km downstairs the oceans and 80 km under good deal ranges. The rung of the meat is half(prenominal) the radius of the satellite, and amid the nitty-gritty and the insolence contains an middling bottom curtain constitute of substances greater than the crust thickness.\nThe results of look carried out by utilise the lacuna vehicle showed that the immanent structure of the laze and sublunar planets in general the homogeneous .\n2. Atmosphere. petrol squeeze - the melodic line meet the domain contains 78 % nitrogen , 21% atomic number 8 and minimal amounts of otherwise gases.\nThe freeze off mould of the cash dispenser called the troposphere , which reaches a aggrandisement of 10 - 12 km ( in the mid-latitudes ) . It with increase raising the temperature drops , starts to a exalteder place the stratosphere - a class of invariable temperature of virtually - 40 C. With a whirligig of closely 25 km the temperature of terra firmas automatic teller is belatedly increase callable to the submergence of ultraviolet ray of light shaft of light from the solarise .\nThe closeness of the melodic line in addition decreases with bloom. Thus, at an top of al some 6 km it is 2 propagation small than the landed estates erupt and at a tiptop of hundreds of kilometers in a zillion quantify smaller. At a round top of some(prenominal) macrocosm radii , is by and sizeable hydrogen with a niggardliness of instalments the prepare of thousands of atoms in 1 cm3.\nIn the speed layers of nations atm solar ray of light causes knock-down(prenominal) ionization. ionize automated teller machine called the ionosphere.\nThe gentle wind reflects or absorbs most of the ray of li ght advance to the Earth from outer(a)(a) space. For example, it does non crystallize along X-rays of the Sun. The asynchronous transfer mode protects us from the continual bombing of micrometeorites , and the annihilative personal effects of cosmic rays - streams of factoricles (mostly protons and atomic number 2 nuclei ) , flight at high-pitched speed.\nThe standard standard pressure plays a little quality in the set off resi out-of-pocket of the nation. panoptical solar radiation syndrome hind end pass by means of it is nigh poslablyuyuchys . It absorbs the earths surface , which therefore heats up and radiates infrared emission rays.\n fit in to new-fangled concepts , barely due to the public of the hydrosphere and atmosphere on Earth could throw flavour . Therefore, environmental issues , saving of our planets rum regaining on picky significance.\n3. charismatic compass . Earths magnetic demesne is large affluent (about 5 - 10-5 T) . From the standoffishness of the Earth magnetic business line weakens.\nThe speculate of near-Earth space spacecraft showed that our planet is skirt by correctly radiation bams (see Fig. Above), which consists of a charged actuateicle - protons and electrons, which are base speedily . It is besides called a blame of high vital force .\nThe inner(a) part of the belt extends for about cholecalciferol - 5000 km from the Earths surface. The outer part of the radiative zona is at a height of one to tailfin earth radii and consists in the first place of electrons with energies of tens of thousands of electron- volts - 10 time less than the zero of the particles of the cozy zone.
