Which of the following causes tornadoes?
A)
dry climates
B)
condensation
C)
stationary fronts
D)
wind shear

Correct Answer : Option (A) - dry climates

Tornadoes form when warm, humid air collides with cold, dry air.
 
The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing an updraft. The updraft will begin to rotate if winds vary sharply in speed or direction.
 
As the rotating updraft, called a mesocycle, draws in more warm air from the moving thunderstorm, its rotation speed increases. Cool air fed by the jet stream, a strong band of wind in the atmosphere, provides even more energy.
