Explanation:

Hurricanes cover large areas typically hundreds of miles across. Tornadoes are small in meteorological terms, often affecting less than a square mile of an area. A hurricane is a large rotating storm with high speed winds that form over warm waters in tropical areas. Hurricanes have sustained winds of at least 74 miles per hour and an area of low air pressure in the center called the eye. The eye of a hurricane usually only lasts for a day or two before a new eye forms and takes its place. For tornadoes, however, the three sizes are: weak, strong, and violent. Their size is based on how large the tornado is as well as the time that the tornado lasts and how it compares to the Enhanced Fujita Scale.
