Q

An instrument useful in predicting fog is the __________.

🔍 Key Concepts

• Relative humidity and how it relates to fog formation • Which instruments measure moisture in the air versus wind or pressure • How fog forms when air is cooled to its dew point

💭 Think About

• Ask which of these instruments tells you about how close the air is to being saturated with water vapor • Consider which instrument is most directly used to measure humidity rather than just temperature, wind, or pressure • Think about what you would need to measure if you wanted to know whether the air is likely to reach its dew point soon

✅ Before You Answer

• Identify which option measures humidity/relative humidity, not just temperature • Eliminate any instruments that are used mainly for wind speed or recording pressure changes • Confirm which instrument specifically uses wet-bulb and dry-bulb readings to assess moisture in the air
