Answer 2

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

Answer :- only earth is the planet having suitable atmosphere for inhancement of life , We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Water vapor and dust are also part of Earth’s atmosphere. Other planets and moons have very different atmospheres, and some have no atmospheres at all.

If we talk about venus it have only Carbon dioxide (CO2) and Sulphuric acid (H2SO4) in it's atmosphere.

and apart from earth & venus , the atmosphere of Mars is much thinner than Earth’s. The Red Planet's atmosphere contains more than 95% carbon dioxide and much less than 1% oxygen. People would not be able to breathe the air on Mars.

So, we can say that atmosphere of Venus and Mars is different from Earth's atmosphere.
