Fog is a cloud that is in contact with the ground. Much like clouds in the sky, it forms when the air becomes supersaturated, meaning that it can no longer hold moisture in the form of vapor. As a result, water precipitates out of the air, forming a fine mist of water droplets.
Radiation fog is fog that is due to the cooling of the earth's surface at night. In the evening, the earth radiates off heat absorbed from the Sun's light during the day. As the warm air rises, the air near the earth's surface becomes cooler. Cold air can hold less water vapor than warm air, and the water vapor in the air near the surface condenses, forming radiation fog. Below is an image of radiation fog occurring over a field.
