Which of the following statements about tornados is incorrect?

The statement that tornados only occur in the middle plains and southeastern states is incorrect because while areas such as "Tornado Alley" in the central United States are known for frequent tornado occurrences, tornados can and do form in many other regions as well. Tornados have been documented in all 50 states, including northern states, coastal areas, and even some urban settings. This wide geographical distribution makes it clear that the phenomenon is not restricted to specific locations.

In contrast, the other statements are accurate descriptions of tornadic characteristics. Tornados can indeed reach extreme wind speeds, with some recorded at speeds exceeding 300 mph. They typically exhibit a rotating, funnel-shaped appearance, which is a key identifier during severe weather events. Additionally, the width of a tornado's path can vary significantly, often spanning from approximately 200 yards to over a mile, indicating that they can cause extensive damage over a broad area. This variability further emphasizes their unpredictable nature and the importance of preparedness in diverse regions.
