Which process describes wind flow influenced by temperature differences?

• A. Air circulation
• B. Cloud formation
• C. Precipitation
• D. Humidity

Answer: (A)

Temperature differences in the atmosphere create areas of higher and lower air pressure. Warmer air rises and cooler air moves in to take its place, setting air in motion—this movement is wind. When this flow continues and circulates around regions, we call it air circulation. On a larger scale, differential heating drives global wind patterns through convection cells, producing systematic wind flow across the planet. So the process described—wind flow influenced by temperature differences—is air circulation. While cloud formation, precipitation, and humidity involve moisture in the air, they are not the process that explains how temperature differences drive wind.
