Answer 1:
The Martian atmosphere has the following gases:
96% carbon dioxide
2% argon
2% nitrogen
For comparison, the Earth's atmosphere is:
78% nitrogen
21% oxygen
1% argon
You might notice there's not a lot of oxygen on
Mars, which would make life difficult for humans.
However, there are many things that can live
without oxygen, and you might imagine that Mars
would be really good for plants! In fact, people
have imagined transforming the atmosphere of Mars
into something that is much more like the Earth.

Oxygen, 0.07% Carbon Monoxide, 0.03% Water vapor,
