The atmosphere on Mars is incredibly thin - equal to about 1% of the density of the atmosphere here on Earth ( Mars equals 0.020 kg/m^3, while Earth comes in at 1.217 kg/m^3). The atmosphere is also mainly composed of carbon dioxide.

More specifically, the atmosphere is made up of five main gases:

  1. Carbon dioxide - 95.32%
  2. Nitrogen - 2.7%
  3. Argon - 1.6%
  4. Oxygen - 0.13%
  5. Carbon Monoxide - 0.08%

Which planet is thin and is mostly made up of carbon dioxide?

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.


What is the smallest part of carbon dioxide?

The smallest particle of carbon dioxide is a carbon dioxide molecule with the formula CO2, which means there are one carbon atom and two oxygen atoms in a molecule of carbon dioxide.


Why is there no air on Mars?

There is air, composed of Carbon Dioxide and Oxygen. The surface pressures aren't enough to allow you to breath it though. That's because of the low surface gravity, pressure, and in part due to it's tenuous at best magnetic field.

What gases do candles give off when burning?

Air is mostly Nitrogen, but that is not the "burning" part; Oxygen is probably what you are looking for, as that is the part that helps the candle burn, without there would be no fire. Or maybe you are looking for Carbon dioxide, that is what burning candles (which are mostly carbon) produces. What gas causes a candle to burn? Oxygen. It is the oxygen in the atmosphere that chemically combines with the wax of the candle to give Carbon dioxide gas and water vapor. What does candle need from air to burn? A candle requires oxygen (O2) to continue its combustion reaction and produce CO2 and H2O.
