Description
↓↓
Fog is a thick cloud of tiny water droplets suspended close to the ground, reducing visibility. It forms when warm, moist air cools and condenses near the Earth's surface. Fog can make travel dangerous by limiting how far you can see, and it often occurs in the early morning or late evening, especially in areas near bodies of water or valleys.
History
↓↓
Fog is a natural weather phenomenon that has existed since the Earth first developed an atmosphere. Ancient civilizations often viewed fog with mystery or as a sign from the gods. In human history, fog has had practical impacts—affecting navigation at sea, travel, and even battles. With the development of meteorology in the 19th century, fog began to be scientifically studied, especially in cities like London where industrial pollution created the famous “smog.”
