Fog forms when air is cooled to the dew point, causing what?

Explanation:
Fog forms when air is cooled to the dew point, reaching saturation so that water vapor condenses into tiny droplets. When the air can't hold any more moisture, the vapor turns into liquid droplets, and those droplets suspended in the air scatter light to create fog near the ground. Humidity isn’t decreasing here; it’s at 100% relative humidity. A rise in temperature would move the air away from saturation, making condensation less likely, and changes in pressure aren’t the primary factor in this process.
