Q

Fog forms when the air temperature is at or below __________.

🔍 Key Concepts

• Dew point: the temperature at which air becomes saturated and condensation begins • Difference between dew point, dry bulb, and wet bulb temperatures • How saturation of air with water vapor leads to fog, clouds, or dew

💭 Think About

• Which temperature condition tells you that the air can no longer hold all its moisture, so water must condense into tiny droplets? • Is fog more like frozen precipitation at a specific temperature, or like a cloud that has formed at the surface because of condensation? • Among the listed temperatures, which one directly indicates when condensation (like fog, dew, or cloud formation) will start in a given air mass?

✅ Before You Answer

• Be clear on the definition of dew point and how it relates to condensation and fog • Distinguish measurement instruments: dry bulb vs wet bulb vs dew point — they are related but not the same thing • Remember that fog can occur at many temperatures above 32°F, so a fixed freezing temperature alone is not the controlling factor
