<human>:  What is the difference between a tornado and a hurricane?
<bot>: The main difference between a tornado and a hurricane is that a tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud, whereas a hurricane is a type of tropical cyclone that is characterized by strong winds, heavy rainfall, and a low-pressure center. Tornadoes are typically found in the mid-latitudes and can develop from powerful thunderstorms, while hurricanes typically occur in the tropics and are fuelled by warm ocean waters. Tornadoes occur over land, whereas hurricanes typically move over open ocean waters before reaching land.
