Barometric pressure is synonymous with atmospheric pressure: True or False?

Barometric pressure is synonymous with atmospheric pressure: True or False?

• A. False
• B. Only at sea level
• C. True
• D. Depends on humidity

Answer: (C)

Barometric pressure is the force exerted by the weight of the air in the atmosphere, measured by a barometer. That measurement is the same as atmospheric pressure—the pressure of the surrounding air at a location. So they are two ways of referring to the same thing. It changes with altitude and weather systems, which is why you’ll see different values at different places and times. Humidity doesn’t change the basic idea that barometric pressure is atmospheric pressure, though the presence of water vapor can subtly affect air density. The statement is True.
