Why Do Tornadoes Hate America?
 
03:49
On the 4th of July, Americans like to celebrate the things that make the United States unique, and a lot of those things have to do with our geography. That remarkable geography is also responsible for some pretty unique weather, and unfortunately for the millions of people living in the Midwest, that weather includes tornadoes. In this episode of SciShow, Hank explains why scientists think the U.S. is prone to so many tornadoes. Like SciShow?
