Question 1. How is our air different from air of Venus and Mars ?

$\huge{\boxed{\rm{\red{Answer}}}}$

Answer 1. Earth's atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide. The amount of carbon dioxide on these planets can range from 95% to 97%.

That's the reason of difference between Earth's and Other given planets atmosphere.

Answer 2

Explanation:

1 it is answer of mars

Its thin atmosphere means that even though there is a large concentration of carbon dioxide, the greenhouse effect is quite weak and needs to be boosted. ... Compared with Earth, there is also very little ozone on Mars, and the thin Martian atmosphere allows much more solar-UV to reach the surface.

2 Venus - Venus is sufficiently strongly heated by the Sun that water vapor can rise much higher in the atmosphere and be split into hydrogen and oxygen by ultraviolet light. The hydrogen can then escape from the atmosphere while the oxygen recombines or bonds to iron on the plants surface
