Which phenomenon is the movement of air from high-pressure to low-pressure areas?

Which phenomenon is the movement of air from high-pressure to low-pressure areas?

• A. Barometer
• B. Humidity
• C. Wind
• D. Precipitation

Answer: (C)

Air moves from regions of higher atmospheric pressure to regions of lower pressure because of the pressure gradient. This movement creates what we call wind. The bigger the difference in pressure, the faster the air will flow from the high-pressure area toward the low-pressure area. Devices like a barometer measure pressure but don’t describe motion; humidity relates to how much water vapor is in the air, and precipitation is the falling of water from clouds. So the phenomenon described by air moving from high to low pressure is wind.
