Humorous answer: greenhouse gasses Correct Answer: Carbon dioxide, just like when outside and not in a greenhouse.
No, the greenhouse effect is the effect of certain gasses such as carbon dioxide and methane (called greenhouse gasses) trapping heat near earth's surface. There is a natural greenhouse effect that keeps earth from becoming too cold, but there is some concern that human actions may be putting extra greenhouse gasses into the air and causing average temperatures to rise.
Nature creates greenhouse gasses by having cows fart.
Mars does have very small amounts of greenhouse gasses, but not enough to help warm the planet.
Neither type release greenhouse gasses
Carbon dioxide (CO2) and methane (CH4).
