Eh, when we talk about this thing called relative humidity, it’s just how much water is in the air compared to how much the air could hold. If it’s all full up, we say it’s 100%. Now, if it’s 50%, that means the air’s got half of what it can hold. So, let’s say you’re sittin’ outside, sweatin’ under the sun, if the air’s got more water already in it, it ain’t gonna take your sweat away much, now is it? That’s what happens when the relative humidity is high. You sweat, but it don’t go nowhere.
Ya see, when the air gets warmer, it can hold more water. So, in the summer, ya might notice that it feels more sticky-like. That’s ’cause the air can hold all that water from the lakes, rivers, and even your sweat. In the Earth Science Reference Tables they show all kinds of measurements, but when it comes to relative humidity, that’s one that helps ya understand just how wet or dry the air is.
If you ever looked at them tables, they got charts and maps for all sorts of things like how much water’s in the air at different temperatures. There’s this one chart in there, tells ya how to figure the relative humidity. You gotta know the temperature and how much water is in the air, then you can look it up, and the table will tell ya the percentage. It’s real handy, especially if you’re tryin’ to know if it’s gonna rain or if it’s good weather for dryin’ clothes outside.
- Relative Humidity: This is how full of water the air is, based on its temperature. When the air is 100% full, it can’t take no more water.
- Temperature: Warmer air can hold more water than cold air. That’s why in winter it feels drier and in summer it feels sticky.
- Saturation: This happens when the air can’t hold no more water. Like when you got a sponge and it can’t soak up another drop.
In them Earth Science Reference Tables, they also tell ya that relative humidity ain’t just about how much water is in the air, but it’s about how much compared to the temperature. You could have a lot of water in the air on a cold day, but if the air ain’t warm enough, it might not hold it all, and you could end up with fog or rain. That’s why sometimes it feels chilly and wet when it ain’t even rainin’.
Now, if you’re ever usin’ these tables, especially for the Earth Science Regents Exam, you’ll want to be familiar with this. They got all sorts of helpful stuff, not just about relative humidity, but about the Earth’s layers, minerals, and even maps that help ya figure out where you are based on the stars or the sun. It’s like a big ol’ treasure map for
