A tornado is a fierce rotating air and debris funnel that starts as a cumulonimbus cloud. Most tornadoes last only about 10+++ minutes.

A lot of tornadoes are "Different from what Dorothy saw"-(www.chaseday.com/tornadoes.htm)

dust devils- these tiny tornadoes usually occur in very warm desert areas. Unlike how most other tornadoes form,(by a cloud) these guys form when the surface becomes cooler than the air, and rises dirt coming along with it. alike to any other tornado, the coreolis effect spins it around in a counter-clockwise direction, and an updraft forming the eye of the tornado.

water devils-evils are the "aquatic cousins of dust devils"-(Dangerous weather:Tornadoes, Michael Allaby) These close cousins to the dust devis, are often found in freshwater lakes. Like dust devils, these aquatic devils are not formed by a cumulonimbus coud, or any cloud for that matter. These tornadoes are formed by strong winds pushing against each other in a spinning motion. Soon, just as the dust devils were formed, the water devils were formed alike to them.

wedge tornadowedge tornadoes may be on the larger side of tornadoes, but they are one of the weaker ones. though they may not be very strong, they cover a much wider path than a classic tornado would. These tornadoes are formed-unlike the dust, and water devils-like a normal tornado that you see in movies.

rope stage-"everytornado has a life cycle" -(chaseday.com) The most violent belive it or not, the rope stage. The reason it is called the rope stage is because from far away, the tornado appears to look like a string being shaken frantically from a cloud.It is the strongest, most dangerous form of a tornado.
