Q

Fog generally clears when the __________.

🔍 Key Concepts

• fog formation and dissipation in relation to temperature, wind, and humidity • how mixing of air by wind affects fog density • the difference between what will usually clear fog versus what might only move or thicken it

💭 Think About

• Think about what happens to relative humidity when the air temperature rises while the amount of moisture in the air stays the same. • Consider whether a mere change in wind direction necessarily changes temperature or moisture, or if it might just push the fog somewhere else. • Ask yourself how increased wind speed affects the mixing of moist and dry air, and whether light, moderate, or strong winds are best for actually clearing fog.

✅ Before You Answer

• For each option, ask: does this change reduce relative humidity enough to drop below 100%? • Decide whether a factor just moves the fog versus actually dissipating it. • Before choosing "All of the above," confirm that every single listed condition would, by itself, normally help fog to clear rather than sometimes make it worse.
