Q

When compared to air temperature, which factor is most useful in predicting fog?

🔍 Key Concepts

• Fog formation and the role of cooling air to its saturation point • The relationship between air temperature, dew point, and condensation • How relative humidity is affected as air temperature approaches a certain key value

💭 Think About

• Think about which option directly tells you how close the air is to becoming saturated and forming tiny water droplets. • Ask yourself: if I know the air temperature, which additional measurement lets me judge how soon condensation (and fog) will occur? • Consider which choice is commonly paired with temperature in weather forecasts to indicate damp, misty, or foggy conditions.

✅ Before You Answer

• Identify which factor, when compared with air temperature, indicates how close the air is to saturation. • Eliminate any choices that do not directly tell you when condensation will begin. • Focus on the variable that, when nearly equal to the air temperature, signals a very high chance of fog.
