Earth, Mars and venus all have nitrogen and Carbon dioxide in their atmosphere, though the levels vary from planet to planet.
EARTH
carbon dioxide and nitrogen
The planet Venus has nitrogen, carbon dioxide and smaller amounts of other gases. Most of the gas is carbon dioxide.
The gases that surround the planet Mars are carbon dioxide, oxygen, methane, nitrogen and argon. Carbon dioxide makes up the majority of the atmosphere of Mars.
the atmosphere of palnet venus is mainly contained by; carbon dioxide and a small amount of nitrogen.
Mostly carbon dioxide (96.5%). Most of the rest is nitrogen.
The scientific name for the gasses that surround a planet is atmosphere. The atmosphere of earth is made of nitrogen, oxygen, and carbon dioxide.
79% Nitrogen, 20% Oxygen and 1% argon, Carbon Dioxide and other trace gasses.
The scientific term for air is "atmosphere." It is a mixture of gases that surround a planet and is composed primarily of nitrogen and oxygen.
Mars is the terrestrial planet with a thin carbon dioxide atmosphere. Venus also has an atmosphere of carbon dioxide, but it is very thick.
Such an atmosphere on a planet would be the result of carbon dioxide emitted from volcanoes.
