Tornado Damage Levels: F0-F5

Did you know that no other country in the world gets more tornadoes than we do right here in the United States of America? Because the cold air that comes over the Rockies meets the warm air in the plains, we have the perfect conditions for monster tornadoes. In fact, we get anywhere from 800 to 1,000 tornadoes a year! Very few of them are as devastating as the Joplin, MO tornado of last year. Others, like the small tornado that Rob and Haley got stuck in for this video, do minimal damage. So how do scientists classify tornadoes? If you guessed wind speed, you’re not exactly correct. Watch this week’s science video to find out! Learn more about Rob and Haley's tornado adventure here.
