What is the difference between FOG and MIST?
We have just learnt about water up in the air condensing high in the sky to form clouds. However, this moisture can also condense closer to the ground, to form what we know as mist and fog. Mist or fog?… But what is the difference between mist and fog? The answer lies in their thickness – and how far we can see through them (ie: the visibility). If we can see less than 1 km through the cloud of water droplets, it is known as fog. If we can see between 1 and 2 km, we call it mist. ————————————–… Key fact: although mist and fog look like smoke, they are actually tiny drops of water floating in the air. In fact, they are clouds that have formed at ground level. ————————————–… Condensation… Mist and fog usually form at night when the air is too cold to hold all its moisture. Clear skies mean that the ground gets cold and it then cools the air close to it. This cool air causes condensation and water droplets form in the air. Fogs are thi
