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.
 
A good question is, what's behind this invisible force that can tickle a cheek one second, and topple a building the next?
 
Wind is just air moving around, and air is just a bunch of dancing molecules. Gravity pulls down on the molecules and 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, so 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.

    According to the article "What Is Wind?" wind can both uproot a tree and someone's life. Based on the text wind can be very dangerous or very calm and relaxing. Finally I know that wind can do those things, because it can uproot the tree and slam it into a house which causes a person and force them to move.
