Mars has a thin atmosphere, mainly of Carbon Dioxide. Its surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.
Venus' atmosphere is mostly composed of carbon dioxide (96.5%) with small amounts of nitrogen and traces of other gases. It also contains clouds of sulfuric acid that contribute to the planet's extreme heat and pressure on its surface.
I believe the planet with low air pressure and that is mostly made of CO2 is Mars.
Mars has an atmosphere with low air pressure which is mostly carbon dioxide.
it is mars. its surface pressure is 600Pa and has 95% co2
That's MARS.
Mars is known as the red planet. The planet itself is mostly rock. It is the thin atmosphere that is mostly carbon dioxide.
Venus
Mars.
Mars is the only planet that is thin and is made up of only carbon dioxide. :) (Question to asker): Define "thin" at what part of it is made of CO2? But you probably mean the atmosphere so in that case then the answer above is correct... mostly.
Venus has a dense atmosphere that consists primarily of carbon dioxide. The pressure of the atmosphere on Venus's surface is 90 times that of Earth's atmosphere.MarsMars.Venus and mars have low air pressure and are mostly made up of carbon dioxide
No. Mars is a "terrestrial" or "earth-like" planet. Mars is mostly rocky, although there is a very thin atmosphere of 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).
