What is the range in which a tornado occurs?

Tornadoes can occur in various geographical locations, but they are most commonly found in the United States, particularly in an area known as "Tornado Alley," which includes parts of Texas, Oklahoma, Kansas, Nebraska, and South Dakota. They can form in any state, typically when warm, moist air collides with cooler, dry air. Tornadoes can develop in severe thunderstorms and are generally most prevalent during spring and early summer. Their occurrence is also noted in other countries, including Canada, Australia, and parts of Europe.
