Final answer:
The state with the largest number of violent tornadoes is Oklahoma.
Step-by-step explanation:
The state where the largest number of violent tornadoes occur is Oklahoma. Tornadoes are more frequent in certain regions due to their unique geographic characteristics. Oklahoma is located in an area known as Tornado Alley, which stretches from central Texas to northern Iowa, and experiences a high frequency of tornadoes due to the collision of warm, moist air from the Gulf of Mexico with cool, dry air from the Rocky Mountains. This collision creates the ideal conditions for tornado formation.
