<human>:  What is the difference between a hurricane and a tornado?
<bot>: The primary difference between a hurricane and a tornado is that a hurricane is a large, rotating storm system with strong winds, typically forming over warm ocean waters, while a tornado is a narrow, violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud. Tornadoes generally develop from powerful thunderstorms, whereas hurricanes develop from tropical disturbances. Hurricanes often cause significant damage over large areas and with sustained winds, whereas tornadoes generally last for a few minutes and can cause localized damage.
