Why is there so much fog in rural areas and so little fog in cities?

Because the humidity in the country is high. When the humidity in the air reaches 100%, the temperature drops, and the water vapor in the air cools and condenses into small water droplets, which is fog. When fog appears, the visibility near the ground is relatively low. Knowing the formation process of fog, we can know that fog is actually a physical phenomenon.

Physical phenomena cover a wide range of contents, among which physical phenomena such as evaporation, sublimation, liquefaction, solidification and sublimation often appear in the weather.

The extended data is different from the formation process of fog, and the dissipation of fog is a vaporization phenomenon, which is also a phenomenon. Contrary to the concept of liquefaction, this is a process from liquid to gas. When the temperature rises, the water droplets in the fog will become gaseous and evaporate and disappear into the air. Therefore, the formation and disappearance of fog is a physical phenomenon.

In fact, fog can be divided into many types of phenomena. That is, fog itself is a weather phenomenon; According to the formation process, it can be defined as a physical phenomenon; Bigger is a natural phenomenon. But no matter what kind of phenomenon, it will always have a certain impact on our lives.
