On both Venus and Mars, the most abundant gas in the atmosphere is carbon dioxide. On Earth nitrogen is the most abundant gas.
Mars has an atmosphere of about 95.72% carbon dioxide. Venus has an atmosphere of about 96.5% carbon dioxide
There are two such planets, Mars and Venus. Venus has a much thicker atmosphere than Mars, but both atmospheres are about 95% carbon dioxide.
It is similar to the composition of the atmosphere of Venus. They are both made almost entirely of carbon dioxide.
Mars & Venus
Venus is very hot with poisonous gases in the atmosphere, Mars is very cold with a low atmospheric pressure.
Both Mars and Venus have atmosphere made mostly of carbon dioxide. The atmosphere of Venus is much denser.
Venus and Mars haveatmospheres mostly consisting ofcarbon dioxide.
Venus has the most carbon dioxide atmosphere of any planet in the solar system, with about 96.5% of its atmosphere composed of carbon dioxide. This thick atmosphere contributes to the planet's extreme greenhouse effect and high surface temperatures.
Both Venus and Mars have atmospheres that are mostly carbon dioxide. However, Venus has a very thick atmosphere. The Martian atmosphere is very thin, so the answer is Mars.
Venus and Mars are both terrestrial planets like Earth, but they differ in their atmosphere compositions and surface conditions. Venus has a thick toxic atmosphere mostly composed of carbon dioxide, strong greenhouse effect, and extreme heat, making it the hottest planet in our solar system. Mars, on the other hand, has a thin atmosphere, cold temperatures, and evidence of liquid water in the past.
