Question

What is the difference between Fog and dew?

Answer 1

Hint: Fog and dew are closely related meteorological conditions that might be difficult to distinguish when describing or observing. Fog and dew are very different in their creation, content, and appearance. Mist and frost are concepts that are closely linked to fog and dew. Fog is abundant in light winds and is similar to mist, which is thinner and more common in mountains and forests.

Complete answer:
Fog is a type of atmospheric phenomenon in which a cloud appears close to or at the earth's surface. It's a dense cloud that can drastically restrict visibility. Motorists have a difficult time seeing in the fog, even when vehicle lights are turned on. Strong gusts and the sun might eventually make the frog vanish and clear the path. When the air cools to the degree that condensation develops, fog is formed.

Condensation, on the other hand, occurs when the temperature falls below the dew point. It appears as fine water droplets on grass, twigs, leaves, and metal surfaces. Dew can be measured with a dew gauge despite being made up of small water droplets.

Dew, unlike fog, has no effect on visibility. It arises at night, just like fog, when moisture condenses on the earth's surface. The air temperature above ground level is cooler than the air temperature below ground level.
Fog is a dense fog that appears close to or on the surface of the earth. Its thickness, on the other hand, may not be constant across the entire surface. There may be some blemishes. On the other hand, dew is the condensation that collects on the earth's surface and can be seen on twigs, leaves, grass, and metal surfaces.

Formation of Dew and Fog: The production of dew is aided by calm winds. The air at ground level has a cooler surface than the air above it. The temperature lowers to the condensation level as a result of radiation cooling, and dew develops. Fog arises as the air above the ground cools due to low wind velocity. All of these atmospheric conditions are more common at night, therefore they are visible in the mornings.

Fog and dew are more common at night. They are also formed in cold climates. Due to the instabilities of the chilly breezes, fog is uncommon in sloppy places. Instead, wind blows down the hills, keeping the area cool.

Note:-
In a word, mist is a lighter variant of fog that forms under particular conditions, while frost forms after dew when temperatures fall below freezing. Fog forms at night and appears as a dense fog close to or at the ground in the morning. Dew occurs at night and shows as condensation on leaves, grass, twigs, and metal surfaces in the morning. In chilly climates, fog might stay all day.
