No atmosphere poisonous or otherwise
Well to be honest mars isn't poisonous.
No, Mars is made mostly of rock.
no, but the air is too thin to breath.
Its red, dusty, and poisonous. MAYBE have life existing on there
Mars's atmosphere is poisonous. The atmosphere is mainly carbon dioxide which is not poisonous in small amounts, but is harmful in large amounts, like on Mars. Also you would die anyway because there's no oxygen.
It is not because the rust on the planet makes the frozen water poisonous.
There is no chance of life on Mars. There was once life on Mars. But as a result of the activities of its landscape, the atmosphere if filled with poisonous gases cannot sustain life, and there are also a lot of volcanoes and earthquakes everywhere in Mars.
Venus is very hot with poisonous gases in the atmosphere, Mars is very cold with a low atmospheric pressure.
Neither Venus nor Mars have appreciable amounts of water. Venus is shrouded in dense, poisonous clouds at very high temperatures; Mars has very little atmosphere.
Mars is called the red planet.mars is the forth planet for the sun.the dust on Mars is poisonous and it is red because of the iron
Mars' atmosphere is mostly carbon dioxide with trace amounts of other gases, but it does not contain any toxic gases that would pose a threat to visitors. However, the thin atmosphere and lack of oxygen make it inhospitable to human life without life support systems.
I think its extremely unlikely that there is life on Mars .One the main reasons is that mars' atmosphere is made up from carbon dioxide (95.32%) this means that if humans breathed it in it would kill us this is because carbon dioxide is poisonous . Also there is little water on mars (0.03)so it would be very hard for any bacteria, plants or humans to survive with so little waterHope this helps X
