Mars explained

Atmosphere MarsMars surface characteristics have consequences for the Martian atmosphere
The absence of plate tectonics and the very little volcanic activity are important to understand why Mars has a far smaller greenhouse effect than Earth.

Due to a weak greenhouse effect the average temperature is about -63°C with huge differences between day and night.

Atmosphere MarsMars, atmosphere without ozone layer
The atmosphere of Mars does not have a protective ozone layer and contains 30 times less water vapour than Earth's atmosphere.
