Distance fog

Distance fog is when things far away look blurry or faded out. It happens because there's moisture in the air, like when you blow on a window and it gets foggy. The moisture makes it harder for you to see things that are far away. It's like looking through a foggy window, everything past a certain point becomes harder and harder to see. Sometimes, game developers use distance fog in video games to create a spooky or eerie feeling, or to help make less powerful computers run the game better. So, if you ever see something far away in a game and it looks blurry, that's distance fog!
