What is wind?

[FrozdY]

I was wondering what wind really is? it's not a solid and it's not a liquid, in yet it can effect us, interact with us, we know how to harness it and create it, but have we really asked our selves what it really is?

 

I know that this might seem insignifigant but if this is insignifigant then everything is and if everything is then there'll be no progress.

and also what is it that makes it move, why does it move, why isn't it affected by gravity? this is something that is like gravity, we can't see it in yet it effects us, keeps us on the ground and it's also invisible to the human eye

Have you heard of gas?

Wind is the movement of Earth's atmosphere due to the Earths rotation and solar heating, the atmosphere is mostly nitrogen with a lesser amount of oxygen and some trace gases...

As an add on to Moontanman's point..

The heating leads to pressure differences, which cause fluid flow (in this case, air).

Sorry, didn't mean for you to hear that.

I've always relied on the definition of wind as the change in air pressure and density. For example: If you have hot solar heat in one area, that hot air will rise, causing cooler air to rush into its place, i.e change in pressure

wow, i really joined a nice forum, i've always wondered what it was, how it's moving and such, thanks all
