Fog

Fog is a weather phenomenon characterized by the presence of tiny water droplets suspended in the air near the ground, resulting in reduced visibility. It forms when the air cools and water vapor condenses. Fog can occur under various conditions, often during calm, humid weather, and is typically classified into different types based on its formation mechanisms, such as radiation fog, advection fog, and evaporation fog. The visibility in fog can range from a few meters to less than 1 kilometer, significantly impacting travel and outdoor activities.
