Question:

How is our atmosphere different from the atmospheres on Venus and Mars?

Answer:

Earth’s atmosphere is different from those of Venus and Mars. The atmosphere of Earth contains a mixture of nitrogen (78.08%), oxygen (20.95%), and a small fraction of carbon dioxide (0.03%), water vapours and other gases. This makes the existence of life possible on Earth. On the other hand, the atmosphere on Venus and Mars mainly contains carbon dioxide, i.e, about 95-97%. It may be the reason that due to this, no life is known to exist in both Venus and Mars.
