<human>:  Explain the difference between a hurricane and a tornado
<bot>: A hurricane is a tropical cyclone, or large system of winds, that forms over warm ocean waters and is characterized by very low atmospheric pressure and heavy rain and wind. Hurricanes can cause extensive damage to coastal areas due to flooding and violent winds. Tornadoes, on the other hand, are much smaller rotating columns of air that form over land and not over oceans. Tornadoes are characterized by rapid and rapid-changing wind speeds, powerful updrafts and downdrafts, and large hailstorms. Tornadoes have the potential to cause much more localized damage than hurricanes.
