Fog And Mist Quiz – Clouds at Ground Level

Fog is a cloud that forms at ground level when air cools to its dew point and water vapor condenses into tiny droplets. Mist is a thinner version with better visibility.

Different conditions create different fogs. Radiation fog forms on clear nights as the ground loses heat, advection fog forms when moist air moves over cold surfaces and sea smoke rises when cold air passes over warm water.

Fog affects travel, safety and even water supplies. Coastal deserts use fog nets to collect drinking water, while pollution mixed with fog once created deadly smogs. Today, forecasts warn drivers and pilots about dense fog.
