Does high humidity or high temperature cause fog?

High humidity is the main factor that causes fog to form. When warm, moist air cools rapidly, the water vapor in the air condenses into tiny water droplets, creating fog. Temperature plays a role in this process by influencing how quickly air can cool and reach its dew point.


If the relative humidity is high and the temperature drops water vapor may .?

condense


Why does the windshield of a car fog up?

The presence of high humidity, and a difference in temperature between the inside and outside.

Can your eyes fog up like glasses?

Yes, your eyes can fog up like glasses when there is a sudden change in temperature or humidity, causing condensation to form on the surface of the eye.


What is formed by water vapor in the air?

Water vapor in the air can form clouds, fog, or mist depending on conditions such as temperature and humidity.

When the humidity is high and the temperature is lowfog often formsWhy?

When humidity is high there is lot of moisture which means a high dew point. When the temeprature drops to the dew point at night or early morning then the air can no longer hold the moisture and it condenses and forms fog.


How is fog tracked?

Fog is usually tracked by taking readings of temperature and humidity. Fog can sometimes be spotty but usually can be predicted with great accuracy.


What must be present in order for a fog to happen?

high humidity


Can humidity be seen?

No, humidity itself is an invisible gas. However, you can see its effects in the form of mist, fog, or condensation when high humidity levels cause water vapor to condense into water droplets.


How can fog form when its really cold?

Fog forms when the air has a high relative humidity, the water vapour condenses to form very small droplets, which remain suspended in the thermal currents of the air. This occurs when the air temperature, is above the freezing temperature of the water. Below this temperature, the water freezes and fall to the ground to form Frost. At sub-zero temperatures, the air is very dry.
