Define the word "dew."

Dew is the moisture that forms on surfaces during the night when the temperature drops and the air becomes saturated with water vapor, causing condensation.

Dew is water vapor that condenses on cool surfaces near the ground when the air temperature falls below the dew point. It is most common in the early morning or evening when the air is cool and the ground is still warm. Dew is not usually visible until the sun rises and warms the ground, causing the water vapor to evaporate.
