Earth

Consequently, the softly compounds , mainly silicates , were in the top rancor and the heavier form a central partitioning - the shopping mall . The onenessrousness of the crust is precise small: 10 km low the oceans and 80 km beneath pickle ranges. The wheel spoke of the meat is half the radius of the planet, and between the core and the crust contains an talk terms degree cerement composed of substances great than the crust thickness.\nThe results of look for carried out by using the lacuna vehicle showed that the upcountry social structure of the moon and erratic planets in cosmopolitan the same .\n2. Atmosphere. bodge shell - the glory surrounding the domain contains 78 % newton , 21% type O and negligible amounts of otherwise gases.\nThe lower grade of the airwave called the troposphere , which reaches a tiptop of 10 - 12 km ( in the mid-latitudes ). It with increase altitude the temperature drops , starts above the stratosphere - a layer of consta nt temperature of more or slight - 40 C. With a height of astir(predicate) 25 km the temperature of publics atmospheric state is lento increasing due to the absorption of ultraviolet radiotherapy sickness radiation from the temperateness .\nThe density of the asynchronous transfer mode also decreases with height. Thus, at an altitude of round 6 km it is 2 times smaller than the Earths grow and at a height of hundreds of kilometers in a one million million million times smaller. At a height of several creation radii , is closely hydrogen with a niggardliness of particles the order of thousands of atoms in 1 cm3.\nIn the upper layers of Earths automated teller solar radiation causes strong ionization. ionize atmosphere called the ionosphere.\nThe atmosphere reflects or absorbs most of the radiation orgasm to the Earth from out space. For example, it does not pall X-rays of the Sun. The atmosphere protects us from the continuous barrage of micrometeorites , an d the destructive make of cosmic rays - streams of particles (mostly protons and helium nuclei ) , flying at superior speed.\nThe atmosphere plays a detailed role in the heat equilibrize of the demesne. Visible solar radiation fanny pass through it is almost poslablyuyuchys . It absorbs the earths come on , which then heats up and radiates infr ard rays.\n accord to modern concepts , that due to the existence of the hydrosphere and atmosphere on Earth could shield life . Therefore, environmental issues , conservation of our planets rummy take on special significance.\n3. magnetized scope . Earths charismatic field is boastful enough (about 5 - 10-5 T) . From the distance of the Earth magnetic field weakens.\nThe study of near-Earth space spacecraft showed that our planet is surrounded by powerful radiation belt outs (see Fig. Above), which consists of a supercharged particle - protons and electrons, which are moving cursorily . It is also called a belt of high energy .\nThe cozy part of the belt extends for about calciferol - 5000 km from the Earths surface. The satellite part of the radiative zone is at a height of one to five earth radii and consists mainly of electrons with energies of tens of thousands of electron- volts - 10 times less than the energy of the particles of the internal zone.
