Which term refers to atmospheric pressure exerted by air at a location?

• A. Temperature
• B. Barometric pressure
• C. Humidity
• D. Wind

Answer: (B)

Atmospheric pressure is the force that the air above a location exerts on that location. The term for this pressure is barometric pressure, and it’s what a barometer measures. Temperature describes how hot or cold the air is, which affects how many molecules are moving but doesn’t define the pressure itself. Humidity is the amount of water vapor in the air, not the force of the air’s weight. Wind is the movement of air caused by pressure differences, not the pressure value itself. Barometric pressure is typically reported in units like millibars or pascals and changes with altitude and weather systems.
