Kansas is the correct answer because it is located in an area known as Tornado Alley, which experiences a high frequency of tornadoes. Tornado Alley stretches across the central United States, including parts of Kansas, Oklahoma, and Texas. These states are prone to severe weather conditions that are conducive to tornado formation, such as warm, moist air from the Gulf of Mexico colliding with cool, dry air from the Rocky Mountains. This collision creates the perfect conditions for tornadoes to form, making Kansas the state with the most tornado activity.
