how does fog form in simple terms

Answer 1

Fog forms when warm, moist air cools and condenses into tiny water droplets suspended in the air. This usually happens when the temperature drops at night or when moist air moves over cooler surfaces. When the water vapor in the air cools to its dew point, it turns into tiny droplets, creating the fog that we see. Essentially, fog is just a cloud that is close to the ground!
