Question

what is difference between fog and dew?

Answer 1

Fog is formed when warm and moist air moves along the surface of colder region. It's temperature goes down to dew point.

Dew occurs when cold air holding moisture comes in contact with objects like flowers,leaves etc. Condensation takes place resulting in formation of tiny droplets of water called dew.

⭐️Key differences between fog and dew:-

⏺️Definitions of Fog and Dew

Fog is a thick cloud that appears very close or at the earth’s surface. However, its thickness may not be consistent throughout the surface. There could be some patches.

Dew, on the other side, is the condensation that forms on the earth’s surface, often visible on twigs, leaves, grass and metal surfaces.

⏺️Formation of of Fog and Dew

Calm winds lead to the formation of dew. The surface of air at ground level is colder than the air above the surface. Radiation cooling lead to the temperature drops to the condensation level and then dew forms. When the air above the ground cools under light wind speeds, fog also forms. All these atmospheric conditions normally form at night and are therefore visible in the mornings.

⏺️Occurrence of of Fog and Dew

Fog and dew normally occurs at night. Cold climates also lead to their formation. Fog is rare in sloppy areas due to unstable cool winds. Instead, wind flows down the hills thus preventing cooling.

✨Summary of of Fog Vs. Dew

➡️Fog forms at night and appears in the morning as a thick cloud close to or at the ground

➡️Dew forms at night and appears in the morning as condensation on leaves, grass, twigs or metal surfaces

➡️Fog can last the whole day in cold climates

➡️Dew is common in calm winds and it can freeze to form frost that appears as ice crystals on earthily objects

➡️Fog is common in light wind speeds and is closely related to mist which appears thinner and common in mountains and forest.
