🔍 Key Concepts

• Dew point: the temperature at which air becomes saturated with water vapor • Relationship between air temperature, moisture, and saturation • Difference between possibility and certainty in weather phenomena

💭 Think About

• When air cools to its dew point, what happens to the air’s ability to hold water vapor? • At dew point, is the air guaranteed to produce a specific kind of precipitation, or just reach a certain moisture condition? • Which option describes something that can happen when air is saturated, rather than something that must happen every time?

✅ Before You Answer

• Identify which choices describe precipitation versus reduced visibility/condensation near the surface • Ask: at the dew point, is water necessarily freezing, or can it still be above 0°C (32°F)? • Choose the option that reflects a possible result of saturation, not an automatic requirement.
