Question

In mars oxygen will happens and we can not live in mars why

Answer 1

bcz there is no water in mars

Answer 2

see the reason behind this is that

mars (red planet) has oxygen in its atmosphere

but it is limited as there are no thing which can give oxygen (I am talking about trees)

the soil of mars is enriched with iron

due to this the oxygen gets reacted and iron oxide is formed (rust) due to which we call it as red planet

and about water

scientists has discovered that there is ice present on the planet on the poles so we have water on mars but very limited

and the reason behind no life on Mars is the climate are movement of plates

it is closer to sun therefore it receives more hear and mars observe frequent mars quake every month
