21. 4 - $400 Would you expect the air pressure in the stratosphere to be greater or less than the air pressure in the troposphere? How do you know? Would you expect the air pressure in the stratosphere to be greater or less than the air pressure in the troposphere? How do you know? It would be less because air pressure decreases as altitude increases. It would be less because air pressure decreases as altitude increases.
