Both, the tornado and the hurricane are meteorological phenomena originated by physical changes in the environment. It is not really easy to understand their difference, although it is there.

A tornado is a violent windstorm characterized by a twisting, funnel-shaped cloud. The word "tornado" comes from the Spanish or Portuguese verb tornar, meaning "to turn." Tornadoes form in storms all around the world, most famously in a broad area of the American Midwest and South known as Tornado Alley. Meteorologists don't know exactly why we have tornadoes, but they do know that they usually start when there is a bad thunderstorm with hail and lightning.

A hurricane (or tropical storm, typhoon, or tropical cyclone, depending on strength and location) is a type of low-pressure system which generally forms in the tropics. While they can be highly destructive, tropical cyclones are an important part of the atmospheric circulation system, which moves heat from the equatorial region toward the higher latitudes.

Hurricanes form when a group of thunderstorms come together to form one big storm. Closer to the equator, sea water is very warm and the air has a lot of moisture in it. These two factors help storms grow into hurricanes. The moisture in the air becomes rain, and the warmth of the sea water provides energy that eventually becomes wind.

Tornadoes start during the warmest or most humid part of the day which would be between 4:00 pm and 6:00 pm . The cold air that gets trapped in the warm air will form a dark big black cloud that has air spinning inside, a characteristic that makes tornadoes to be twisting windstorms.
