CBSE Class 9 Answered
Firstly there is no water on the moon which is the first and foremost requirement for the life.
Air is also required to breathe and no air is on the moon. Also oxygen required by human beings to breathe is not enough on the moon for our survival.
Moreover the temperature on the moon is not suitable for the life to exist.
Other than these basic needs, there are several more reasons because of which life is not possible on the moon such as the angle at which the moon is tilted, its speed of revolution around the sun, speed of its rotation around its own axis and distance from the sun etc.
Hope this answers your query.
