A Tornado is a very tall, funnel-shaped whirlwind that can be as high as 2,000 feet. The strong upward current of the tornado sucks up or destroys everything in its path. It has, in its centre a current of descending air vastly different to the destructive upward current that surrounds it. The centre of a tornado can be quite carm, totally different to what is going on around it.
Tornados can be extremely devastatng, as the picture below shows.
