ANSWER from Mary Urquhart on April 3, 1997: You couldn't light a fire on Mars because there isn't oxygen in the atmosphere to react with the material you want to burn. Fire is a chemical reaction where oxygen combines with other substances and produces heat and waste products (like carbon dioxide and soot when you burn wood).
Atmosphere
Nitrogen is more in the atmosphere. Around 78% of the atmosphere is nitrogen gas and 21% is oxygen gas.
Earth's atmosphere is about 21% oxygen by volume (for dry air).
Nitgrogen forms 80% of the Earth's atmosphere and oxygen 21%
Mars' atmosphere contains 0.13% oxygen. Over 95% of the atmosphere on Mars is carbon dioxide.
mars atmosphere is thinner and lacks oxygen or water
Earth has oxygen they don't.
There is a very small amount of oxygen on Mars. The oxygen level in Marsâ?? atmosphere said to be around .145%.
Yes. There is one planet with oxygen in its atmosphere: our home planet Earth.
Planning on going to a trip? Take your own oxygen with you, since you can't breath on Mars. 95.32 percent of Mars' atmosphere contains carbon dioxide. Oxygen level is 0.13% on Mars.
Yes humans will suffocat on Mars. Human depend on Oxygen to breathe and without oxygen, we will die. Oxygen is present in th Earth's atmosphere and it is not on Mars. To survive on Mars, we need to use an astronaut's suit with oxygen support.

No. Earth's atmosphere is made mostly of nitrogen and oxygen. The atmosphere of Mars is much thinner ans is made mostly of carbon dioxide.
A tiny fraction of a percent. Mars has an extremely thin atmosphere, and what it does have is mostly Carbon Dioxide.
Mars has too LITTLE OXYGEN for humans to live on. Earth's atmosphere has about 21% Oxygen at 1 atmosphere of pressure, but you can live on higher percentages of oxygen at lower pressures such as in NASA spacesuits. While Carbon Dioxide is toxic to humans at high concentrations, you would likely suffocate to death from lack of oxygen first on Mars. Search Wiki: Atmosphere of Mars "The atmosphere on Mars consists of 95% carbon dioxide, 3% nitrogen, and 1.6% argon, and contains traces of oxygen, water, and methane..."
Earth's atmosphere is almost 200 times thicker than the atmosphere of Mars. The atmosphere of Earth is primarily nitrogen and oxygen, while the Martian atmosphere is primarily carbon dioxide.
