Fog happens when warm moist air cools down and turns into tiny water droplets that float around like a soft cloud on the ground.

Imagine you're drinking a hot chocolate on a chilly morning. The steam from your cup rises up, that’s warm moist air doing its thing! Now, if that warm air meets cooler air outside, like when you step out of a warm room into the cold, the warm air starts to cool down.

As it cools, the moisture in the air, like tiny droplets of water, can no longer stay invisible. Instead, they condense, or turn from vapor back into little visible drops. These drops hang around in the air, making it hard to see through, just like a soft, fluffy cloud that’s touching your feet.

Think about taking a breath after running outside on a cold day. Your breath turns into a white puff because your warm moist air meets the cool air outside and condenses into tiny water droplets, just like fog!
