What is the difference between a tornado and a hurricane?
assistant
The main difference between a tornado and a hurricane is that a tornado is typically a rapidly rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud, while a hurricane is a large tropical storm system characterized by strong winds, heavy rains, and high seas. Tornadoes are usually much smaller and shorter-lived than hurricanes, and they generally form over land rather than at sea. Hurricanes tend to be more destructive due to their size and intensity.
