The dew will likely mostly burn off when the sun gains strength and thus is not doing very much.

Can you drink dew?

Why does morning dew happen?

Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. … If the object gets cold enough, and there is enough moisture in the air, condensation is much greater than evaporation and the film grows into dew drops.

Why does morning dew disappear after the sunrise?

Answer: When the air temperature is the same as the dew point temperature, condensation occurs on tiny particles floating in the air. … When the sun rises, the air and ground warm up. This leads to the air temperature being warmer than the dew point temperature, which causes the fog droplets to evaporate.

What are three examples of condensation?

Morning condensation (dew) is very common in some regions and can easily be forecasted. The favorable weather elements for dew include clear skies, light wind, decent soil moisture, and low night-time dewpoint depressions. Dew forms when the temperature becomes equal to the dewpoint.

Does morning dew help grass grow?

Dew may also play an important role in seed germination. High levels of dew in grasslands could provide the moisture needed for different types of seeds to germinate, perhaps even creating conditions that support the transition from grasslands to forests.
