A tornado is a violently spinning column of air in contact with both a cumiliform cloud base and the surface.
A tornado is typically shaped like a funnel with the narrow end on the ground.
Tornadoes are known for being extremely destructive and are usually visible due to water vapor from clouds and debris from the ground..
