The atmosphere of Earth strongly differs from the atmospheres of other planets of the Solar system. Having a nitrogen-oxygen basis, the terrestrial atmosphere creates conditions for life which, owing to certain circumstances, cannot be on other planets.
Instruction
1. Venus – the planet, next to the sun, which has the atmosphere, and such high density that else Mikhail Lomonosov in 1761 claimed about its existence. Presence of the atmosphere at Venus so obvious fact that up to the twentieth century the mankind was under the influence of illusion as if Earth and Venus are twin planets, and on Venus the life is possible too. Space researches showed that everything is far not so iridescent. The atmosphere of Venus for ninety five percent consists of carbon dioxide, and does not release outside heat from the Sun, creating greenhouse effect. Because of it temperature on the surface of Venus is 500 degrees Celsius, and the probability of existence of life on it is insignificant.
2. Mars has the atmosphere, similar in structure to Venus, which is also consisting generally of carbon dioxide, but with impurity of nitrogen, argon, oxygen and water vapor, however, in very small amounts. Despite accepted temperatures of a surface of Mars in a certain time of day, it is impossible to breathe such atmosphere. In protection of supporters of the ideas about life on other planets, It should be noted that planetologists, having investigated the chemical composition of breeds of Mars, in 2013 said that 4 billion years ago on the red planet there was the same amount of oxygen, as on Earth.
3. Giant planets have no firm surface, and their atmosphere on the structure is brought closer to solar. The atmosphere of Jupiter, for example, generally consists of hydrogen and helium with a small amount of methane, hydrogen sulfide, ammonia and water which as it is considered, is in inside layers of this huge planet.
4. The atmosphere of Saturn is very similar to yupiteriansky, and also, mostly, the truth in slightly other proportions consists of hydrogen and helium. Density of such atmosphere is extraordinary high, and we can speak with a big share of reliability only about its top layers in which clouds from the frozen ammonia float, and wind speed sometimes reaches one and a half thousand kilometers per hour.
5. Uranium, as well as other giant planets, has the atmosphere consisting of hydrogen and helium. During the researches which were conducted by means of the devices "Voyager" the interesting feature of this planet was open: the atmosphere of Uranium is not warmed up by any internal sources of the planet, and receives all energy only from the Sun. For this reason Uranium has the coldest atmosphere in all Solar system.
6. The Neptune has the gaseous atmosphere, but its blue color says that in its structure there is a substance unknown so far which gives to the atmosphere from hydrogen and helium such shade. Theories about absorption of red color of the atmosphere methane, did not receive the full confirmation yet.
