Tornadoes
Tornadoes are whirling tubes of air. They are violent and destructive.
They start in huge thunderclouds and stretch all the way down to the
earth. A tornado can have wind speeds of more than sixty kilometres
per hour. Extreme, or very strong, tornadoes can have wind speeds up
to 480 kilometres per hour.
Narrow, wide, fast, and furious …
A tornado can be two metres to four kilometres wide. A tornado that struck the town
of Hallam in Nebraska, in May 2004, was four kilometres long on the ground.
Tornadoes move over the surface of the earth. Smaller tornadoes can move over
an area of four to five kilometres, while bigger ones can race over a hundred
kilometres.
Tri-State tornado …
In 1925, a very powerful tornado swept across the US. It was called the
Tri-State tornado because it moved over three states. As it moved, it
completely destroyed four towns and left six badly damaged. After
the tornado had passed, there was more damage because of
fierce winds and fires. People say that they saw houses
being lifted up into the air and crashing.
The Tri-State tornado is considered the most destructive
tornado in the history of the US because it killed 695 people
and destroyed fifteen thousand homes completely.
The Tri-State
tornado ripped
through the states
of Missouri,
Illinois, and
Indiana.
TICKER The US gets the largest number of tornadoes, while no tornadoes have been recorded in Antarctica.
