What's the Difference Between Fog and Haze? | FX Forum?

Fog and haze are both cloudy things that make it hard to see, but they act like different kinds of blankets over the world.

Fog is like a thick blanket made of tiny water droplets, imagine breathing in a steamy bathroom on a cold morning. It forms when warm air meets cool air near the ground, and it makes everything look fuzzy, almost like you’re seeing through a glass of milk. You can often see fog rolling in from the sea or coming up from the ground like a ghostly friend.

Haze is more like a dusty blanket made of tiny particles, think about how your room looks when there’s a lot of dust floating around after you open a window on a dry day. Haze comes from pollution, like cars and factories, and it makes things look faded, like everything is seen through a dirty window.

So fog is more like the steam from a pot, while haze is more like the dust in your room, both make seeing hard, but they feel different when you're walking through them.
