Dew

Dew is the term for small water droplets that appear on thin objects in the morning. It results from atmospheric moisture that condenses after a warm day and appears during the night on cool surfaces as small drops. The cool surfaces cool the nearby air, decreasing the amount of humidity (dissolved moisture) it can hold. The extra vapor condenses (precipitates out of solution in the air). When temperatures are lower, dew will take the form of ice; this is called frost.
