planet mars
a life on mars?
if we found life on another planet,would that planet be mars? that's one of the questions on the minds of space exerts today.if you ask non-scientists,many will say they believe there could be life on mars.and if we look at the evidence,we'll see that this isn't such a crazy idea.
ิb could we breathe on mars?
scientists have learned that mars seems to be the planet with the best conditions for life,after earth.however,if people went to live on mars tomorrow,they wouldn't be able to breathe.if we compare the air on earth with that on mars,we'll see why not. the air on mars is mainly made up of carbon dioxide (95.32)with 2.7 nitrogen,1.6 argon and only 0.13 oxygen. but the air here and 21 oxygen with a small amount of hydrogen and other gases
c could we live on mars
as far as we know,for life to exist, we need two essentials: air to breathe and water to drink.we now know there isn't enough oxygen on mars for humans to breathe.but there are signs of water on mars.there aren't seas or lakes,but NASA scientists have found ice there and there is also some water in the atmosphere.maybe there could be a way to survive there.
