Answer 1

When condensation occurs closer to the Earth's surface we can see fog, dew or Frost.

1. Fog:- As the temperature of the layers off the air the surface of the earth reduces water vapour condenses it turns into very small water particles and float in the air when the density of the droplets in the air increases fog occurs
2. Dew:- When moisture Laden air near the earth surface comes in contact with very cold objects condensation of vapour takes place and it turns into very small water droplets these water droplets. These water droplets stick to the surface of the cold objects and form dew.
3. Frost:- If the temperature of the air riches below 0 degree Celsius the Dew freezes. this frozen water droplet is called Frost
