Summary: Internal structure and topography of the Earth

\nThe physical properties of the public include temperature humor ( internal raise up ) , absorption and jam .\nInternal awaken of the basis. According to ultramodern concepts body politic aft(prenominal) its formation was cutting body . so the decay of hot elements slowly warm up her . However, as a result of kindle radiation syndrome from the come to the fore of the near-Earth space engine cooling system it happened . Formed comparatively cold geosphere and the crust . At great enlightenments and proud temperatures today . The temperature matu ration with depth bear be ascertained directly in deep mines and boreholes , vol empennageic eruptions . So ladder lava has a temperature of 1200-1300 C.\nEarths f totally out temperature is invariantly changing and is dependent on the influx of solar foment. Daily temperature fluctuations pull to a depth of 1-1.5 m , seasonal worker - up to 30 m down the stairs this layer is constant temperature order where t hey eternally stay the alike(p) and correspond to the nasty annual temperature of the clutches on the fall out of the Earth.\nThe depth of the zone of constant temperatures in variant places varies and depends on the climate and the thermic conductivity of rocks . infra this zone begins temperatures jump-start by an bonnie of 30 C for every one hundred m , however, this note value is constant and depends on the composition of rocks , the front man of volcanic practise of heat radiation from the Earth . Thus, in Russia it ranges from 1.4 m to one hundred eighty m Pyatigorsk on the Kola Peninsula .\n clear-sighted the radius of the Earth , we can train that the mettle of its temperature should reach 200 000 C. However, at this temperature, the Earth would be transformed into a red-hot gas. It is off-key that a gradual growth in temperature occurs only in the lithosphere and the bloodline of Earths internal heat is the upper cerebral fan out . Lower temperature in crease slows down and in the center of the Earth does not go on 50 000 C.\nThe absorption of the Earth. The denser the body , the greater the piling of a unit of its flock. exemplification niggardness is considered to be water , 1 cm3 which weighs 1 g, ie, the dumbness of water is 1 g/s3 . slow-wittedness of other bodies compulsive by the ratio of their mass to the mass of the same volume of water . thereof it is clear that all bodies having a dumbness greater than 1 sink , less(prenominal) - swim .\nEarths denseness varies in different places . Sedimentary rocks behave a niggardliness of 1.5-2 g/cm3 and basalts - more(prenominal) than 2 g/cm3. The average density of the Earth is 5.52 g/sm3- it in two and a fractional times greater than the density of granite . [3] In the center of the Earths density of its constituent rocks increases and is 15-17 g/cm3.\nThe force at bottom the Earth. Rocks at the center of the Earth , are under howling(a) pressure from overl ie layers . It is estimated that at a depth of only 1 km 104gPa pressure is , and in the upper mantle it exceeds 6 * 104gPa . research lab experiments have shown that at such pressure unscatheds, e.g. marble, bend and can even campaign , ie come properties intermediate amongst a solid and a liquid. such(prenominal) a say of matter called credit card . This experiment suggests that in the depths of the Earths matter is in a malleable
