Explanation:

    Tornado Alley is a common term for the central United States that covers the states or parts of states where tornadoes occur frequently. It includes the lowlands surrounding the Mississippi River, the Ohio River, and the Missouri River valleys, as well as the southeastern United States. Although no US region is totally free of tornado phenomena, they are much more frequent in Tornado Alley.

    This abundance of tornadoes in the region is made possible by the encounter of cold air from Canada and hot air from the Gulf of Mexico.
