A cloud at ground level is commonly referred to as fog. Fog forms when water vapor in the air condenses into tiny water droplets that are suspended in the air, creating a thick mist that reduces visibility.
Fog occurs when warm, moist air cools down, especially overnight or in the morning when temperatures drop. The temperature drops to the dew point, where the air can no longer hold all of the moisture in the form of vapor, leading to condensation. This phenomenon can be influenced by various factors including geography, temperature, and humidity levels.
In essence, while clouds typically form high in the sky, fog represents the same process of condensation occurring at ground level, affecting how we perceive our surroundings and potentially impacting travel and outdoor activities.
