Tornado Facts and Safety

The video explores tornadoes, starting with folklore and moving to scientific explanations. It covers Tornado Alley, the formation and characteristics of tornadoes, their impact, and how they are classified using the Enhanced Fujita Scale. The video concludes with a reminder of the power of tornadoes and offers additional resources for learning.
