Which statement is true about the occurrence of tornadoes?

The correct statement emphasizes that tornadoes can occur in various regions of the world. While the United States, particularly an area known as "Tornado Alley," experiences a high frequency of tornadoes, these weather phenomena can also be found in other countries and regions. Places such as Canada, parts of Europe, and even Australia and Bangladesh have reported tornado occurrences. This global perspective on tornadoes is key, as it highlights that they are not limited to one specific area, supporting the understanding that severe weather patterns can manifest in diverse geographic locations.

Other options inaccurately generalize the occurrences and limitations concerning tornado formation. The claim that they mostly happen in Europe overlooks the significant prevalence in the United States and suggests a singular focus that is misleading. Asserting they rarely occur anywhere but the United States ignores documented cases in other parts of the world. Lastly, stating they only occur during summer months is incorrect since tornadoes can form in multiple seasons, although peak times may vary based on regional climatic conditions.
