Warmer air can hold more water than colder air. The air cools during the night due to lack of sunshine, and when it gets so cool that it can't hold any more water (called the dew point), dew forms (or frost if the temperature is below freezing). After sunrise, the air starts warming up. That makes it able to hold more water, so the dew evaporates.

What happens to dew when the sun rises?
When the sun rises, the warmth and light cause the dew to evaporate. As the temperature rises, the water droplets in the dew transform into water vapor and are released into the air.
What happens to dew as the day gets warmer?
As the day gets warmer, dew evaporates into the air. The sun's heat causes water droplets to turn from a liquid state into water vapor, which then rises into the atmosphere.
What happens to dew during the day?
rain comes
Describe what happens when water vapor rises and cools to the dew point?
As water vapor cools to the dew point it converts from a gas back to a liquid.
What forms when arie rises cools to a dew point and then becomes saturated?
what forms when air rises cools a dew point and then becomes saturated
When was Dew-Dew-Dewey Day created?
Dew-Dew-Dewey Day was created in 1927.
Where is dew found?
Typically on any cooling surface in a humid environment. For example, leaves warmed by the sunlight during the day, will collect condensed moisture (dew) as they cool during the evening. When the sun rises and re-heats the leaves, the dew will eventually evaporate.
What happens when water vapor rises and cools the dew point?
When water vapor rises and cools to the dew point, it reaches a temperature at which it can no longer hold all the moisture. This excess moisture then condenses into liquid water droplets, forming clouds or fog.
When the ground has enough moisture and the temperature reaches the dew point what happens?
When the temperature comes down to the dew point, the air can support no more water vapour and the dew begins to to form. Air can absorb more water vapour as the temperature rises, so the difference between the dew point and the actual temperature gives a measure of the humidity.
Why is it foggy in the morning on a sunny day?
Fog can occur in the morning on a sunny day when the ground cools overnight and the air above it becomes saturated with moisture. As the sun rises and heats the ground, the moisture in the air condenses into fog. The presence of fog does not necessarily mean it will be a cloudy day since the fog usually dissipates as the temperature rises.
Why does dew point change day to day?
Because the temperature changes and the dew point is dependent on the temperature.
Why does the dew disappear after sun rises?
Dew appears on grass in the early morning hours. It goes away after the sun is up because the heat of the sun causes the water to evaporate.
