You asked us, what exactly is wind and how does it get blown around?
Wind is a major player here on Earth. It sculpts landscapes, brings rain and uproots trees along with lives.
So what's behind this invisible force that can tickle a cheek one second, and topple a building the next?
Good question. Wind is just air moving around. And air is just a bunch of dancing molecules. Gravity pulls down on the molecules. The closer they get to the Earth's surface, the more tightly packed they become.
Air that's under high pressure like that naturally flows to areas of low pressure. The bigger the difference in pressure, the faster the air flows. And that, my fellow geeks, is wind.
But what causes one area to be higher pressure than another? The sun. It heats the Earth's surface unevenly, creating areas with warmer air, which rises, and cooler air that then rushes in.
All of these air movements happen at both local and global scales. And of course, it's all a lot more complicated than all of this, making wind and weather a little bit unpredictable.
Which is why I never leave home without my trusty cape.
