How does fog form over a lake?

Fog forms over a lake when warm, moist air comes into contact with the cooler surface of the water. As the warm air cools, its capacity to hold moisture decreases, leading to condensation and the formation of tiny water droplets suspended in the air. This process is often more pronounced during early morning or late evening when temperatures drop. Additionally, if the lake is warmer than the surrounding air, evaporation can further contribute to fog formation.
