Nitrogen (approx 79%) & Oxygen (approx 20%). The remaining 1% is made up of argon, neon and other inert gasses.
Venus' atmosphere is primarily composed of carbon dioxide (96.5%) with traces of nitrogen and sulfur dioxide.
a very thin amount of vaporized metal
The composition of the atmosphere is essentially consistent. No one gas determines or affects the weather.
No, quite the opposite really. Volcanoes add to the atmospheric greenhouse gasses.
The three major gasses dissloved in ocean water are nitrogen, oxygen and carbon dioxide.
It never was - Nitrogen is the "major gas".
Jupiter has very strong gravity, extremely high atmospheric pressure, poisonous gasses and probably no surface.
Temperature will decrease as the altitude increases at all levels due to the thinning of atmospheric gasses.
Temperature will decrease as the altitude increases at all levels due to the thinning of atmospheric gasses.
Animal climatology treats the same atmospheric processes as meteorology, but it also seeks to identify slower-acting influences and longer-term changes, including the circulation of the oceans, the concentrations of atmospheric gasses.
Ceres major gases is a big mass. This is what makes up the asteroid belt.
Some of it is atmospheric gasses, some of it (often a quite large part) is methane, and a small percentage is other organic compounds. The "other organic compounds" is the part that's responsible for the smell; methane itself is odorless.
