Final answer:
The pressure in the air is largest at sea level and decreases as we move up in the atmosphere.
Step-by-step explanation:
The pressure in the air is largest at sea level. As we move up in the atmosphere, the air becomes thinner and the pressure decreases. At the top of a mountain, the pressure is lower than at sea level. The pressure continues to decrease as we go higher up, for example at the top of clouds and at the top of the atmosphere.
