Dew in the morning?

Question

where does dew come from?

Answer 1

Dew forms when the air temperature falls low enough to cause water vapor in the air to condense.

Answer 2

The air beneath a temperature inversion has some moisture.   At the temps fall to near the dewpoint,  the air becomes moist and settles on the ground.

Answer 3

Dew is water in the form of droplets that appear on thin,exposed objects in the morning or evening.Water droplets result due to the condensation of moisture at a rate greater than that of which it can evaporate.Dew does not require condensation nuclei (for condensation) as in the case of fog or cloud.

Answer 4

Dew is water condensed from the atmosphere onto objects on the Earth's surface. Dew forms when the air temperature falls low enough to cause water vapor in the air to condense. The temperature at which this occurs is called the "dewpoint". A little more technically, the dewpoint is the temperature at which the air becomes saturated (i.e. the temperature at which the relative humidity would be 100%)
