Where Does the Dew Come from?

On summer mornings we some-times find small sparkling water drops on grass, leaves and flowers. This is called dews. Where does it come from?

In summer when it is very hot during the day, the grass and leaves become hot too. In the evening they cool down. When the moisture in the air meets the cool grass and leaves, it turns into little water drops. This is the dew we see in the morning.
