Hello teachers. Could you help me?

I would like to know if the sentence below is grammatically correct.

"Where is the pressure of the atomosphere lower, on Mars or on Earth?"
If it is incorrect, could you tell me how to express it correctly?

Thank you.
Yukineko.

That's perfectly fine (except it's atmosphere, not atomosphere). You could also say:

"Where is the atmospheric pressure lower, on Mars or on Earth?"

(atmospheric pressure means the same as pressure of the atmosphere)

or you could say:

"Which has the lower atmospheric pressure, Mars or Earth?"
