Why is vertical stability of air important in fog?

Answer and explanation

Correct answer: Stable air prevents droplets from dispersing away from the surface

Correct answer: A. Vertically stable air resists strong upward and downward movement, so there is little vertical mixing. When moist air near the ground cools and forms tiny droplets, weak mixing allows those droplets to remain concentrated near the surface. The fog can therefore persist and continue to reduce visibility. In unstable air, stronger vertical motions mix near-surface air with air above it, which can dilute, lift, or disperse the fog and make it less persistent. A is correct because it expresses the role of poor vertical mixing, although stability does not literally stop every droplet from moving. B is wrong because stable air does not turn rain into sunshine. C is wrong because water vapour can certainly exist in stable air. D is wrong because atmospheric stability does not cause earthquakes. Memory cue: stable air means little mixing, so fog stays near the ground; unstable air mixes it away more easily.
