A tornado is a dangerous weather event that can happen quickly and cause a lot of damage. It is a rotating column of air that can be very strong and can uproot trees, damage buildings, and even lift cars into the air. Tornadoes usually happen in certain parts of the world called "Tornado Alley," which is in the United States Midwest. If you are ever in an area where a tornado is possible, you should seek shelter immediately.
