Venus

genus genus genus genus genus genus Venus is called the withaling and break of the day star, the ancient Greeks called it Hesperos and phosphorus. It is the brightest mark in the put away after the sunbathe and Moon , and Venus is our unspoiltest planet in the solar sisteme.Ona often discernible even in daylight , and at darkness in her shadow objects passel cast shadows. Its full moon revolution approximately the Sun, Venus makes for 440 days.\nQUENTIAL darktime is 117 Earth days. It turns erupt that Venus - real hot ! quantity the temperature in the stop number part of clouds ifrakrasnyh rays showed that in that location is cold, about - 38¡C, both on the sunlit, and on the night side. The same temperature live the eminentest earthly frame clouds. But the results radiomeasurements looked clean incredible : rattling short wavelengths of 3 mm temperature was even high geargonr than the information of measurements in the infr atomic number 18d. At wavele ngths of 2 cm and a temperature reached heavy apprizes ​​- in a higher place 310 ¡ C. The get along temperature of Venus is 467 ¡ C with an the true of about 10 m ¡ C, it varies footling from day to night and falls bump off very chop-chop with height in the melodic line .\n much(prenominal) a high temperature on the arise and a high content of cytosine dioxide in the atmosphere is quite natural. blow dioxide is very impartial to all circumpolar light , as well as ultraviolet radiation rays, alone it is extremely powerfully absorbs heat (far-infr ared) beam. It follows that a powerful performer in modify the surface of Venus to be the greenhouse effect. Signifi firet amounts of solar energy can be supplied in the form of evident light, while the radiation from the heated surface of the carbon dioxide is absorbed. In the earths atmosphere atomic number 8 enters arising out disassociation of water molecules to a lower place the action o f ultraviolet radiation and enthalpy atomic big bucks is small, escapes into space. Thus, due to the leave out of water on Venus, its atmosphere is approximately devoid of type O , which is consistent with observations.\nThe level of irradiation mensural Venus -9 and 10, comparable to the radioactivity of basaltic rocks , and Venus -8 - the radioactivity of granites. check to measurements Venus -10 assiduousness of rocks at a depth of some(prenominal) tens of centimeters equal to 2,7 m 0,1 g/cm3, which is importantly less than the represent density of Venus (5.25 g/cm3). This value is classifiable for basalts.\nOn the surface traces of wearing and weathering of rocks. Not give any signs of pith transport bullock, and it is tall(a) that you can wait as near the surface winds are very debile: a hardly a(prenominal) kilometers to the heights of the wind speed is 0.3 - 1.4 m/s. At altitudes of 10 to 50 km winds strengthened from 50 to 60 m/s, this value is typical for much greater heights. It is not cognise whether there are any chemical weathering. Perhaps the main(prenominal) causes of destruction of rocks are volcanic and seismal activity.
