95.32% carbon dioxide
2.7% nitrogen
1.6% argon
0.13% oxygen
0.08% carbon monoxide
210 ppm water vapor
100 ppm nitric oxide
2.5 ppm Neon
850 ppb HDO
300 ppb Krypton
130 ppb formaldehyde
80 ppb xenon
30 ppb ozone
10 ppb methane
Note: ppm stands for parts per million while ppb stands for parts per billion. 210 ppm of water vapour means water vapour makes up 210/1,000,000 of the atmosphere.
It is similar to the composition of the atmosphere of Venus. They are both made almost entirely of carbon dioxide.
A very thin atmosphere that is similar to Earth's with carbon dioxide, nitrogen, argon, oxygen, carbon monoxide, water vapor, and other gases. also very high in iron and rock (various minerals). The primary composition of Mars is sulfur and iron. It also contains iron oxide on its surface, which gives Mars its red appearance.
mars doesnt have an atmosphere ...
Mars is rocky.
Mars' moons have no atmosphere
Mars has a very thin atmosphere. Based on astronomical measurements and information from Mars probes sent by NASA, carbon dioxide dominates the atmosphere of Mars.
Distribution of methane is in the atmosphere of mars.
The atmosphere on Mars is mostly carbon dioxide.
earth has people in it's atmosphere
the composition of Europa's atmosphere is mostly your idiocracy, and stupidity.
Mars has no rings.
