So one of my lifelong curiosities was about how the wind came to be. Was it something that never died and just went around and around the earth? Or did it have to do with the earth's rotation?

Well my friends, I have finally learned about how wind happens.
It's a lot simpler than I thought. Basically, it has to do with air pressure. When air moves from a high pressure area to a low pressure area, that movement is what wind is.
Here's an example that really helps you understand it. Think of a plane. If you open the door while flying, there will be a giant gush of wind that sort of sucks the air out of the plane. The plane is the high pressure zone and the air outside the plane is the low pressure zone. When these two meet by opening the plane door, wind is created, and since there is such a large difference between the pressures, that is why the rush of air out of the plane - the wind! - would feel so strong.

I hope this satisfies you as much as it did me, yet another little fact to enhance your appreciation of our planet.
