Carbon Dioxide makes up roughly 96.5% of Venus' atmosphere. Nitrogen makes up another 3.5%, leaving trace amounts of other gases.
The dominant atmospheric gases for Earth are nitrogen (78%) and oxygen (21%). Together, these two gases make up about 99% of Earth's atmosphere. Other gases such as argon, carbon dioxide, and water vapor make up the remaining 1%.
The dominant atmospheric gases on Mercury are oxygen, sodium, hydrogen, helium, and potassium. However, the atmosphere on Mercury is very thin, with a pressure about 10^-15 times that of Earth's atmosphere.
there is some sulphuric acid and carbon dioxide with very little water vapor
Venus is very hot with poisonous gases in the atmosphere, Mars is very cold with a low atmospheric pressure.
Venus' atmosphere is primarily composed of carbon dioxide (96.5%) with traces of nitrogen and sulfur dioxide.
As far as we know, no people have died on Venus because humans have not visited the planet. Venus has an extremely hostile environment with high temperatures, crushing atmospheric pressure, and toxic gases, making it impossible for human survival without advanced technology.
The atmospheric gases carbon dioxide, methane and nitrous oxide are all greenhouse gases that help to heat the Earth.
The glass on the greenhouse stops temperature from leaving or entering like the gases do to the earth.The atmospheric gases are called 'greenhouse gases' based on the idea that the gases 'trap' heat like the walls of a greenhouse do
it is hydrogen
carbon dioxide
Presuming you mean which planet has carbon dioxide as the primary component of its atmosphere, and features clouds of sulfur dioxide (or sulfuric acid), which would be Venus, second planet from the Sun (the next innermost planet from the sun compared with earth).
No, Venus does not have a hydrosphere. The extreme temperatures and atmospheric conditions on Venus make it unable to support liquid water on its surface.
