Why does It destroy everything in It's way? And how do tornadoes kill people?
-
Winds rotating at 100 to almost 300mph alone are enough to destroy many structures, but when you add in the debris from everything the tornado has destroyed you have winds plus airborne missiles. A simple 2x4 piece of wood can penetrate a brick house all the way through to interior walls. There's even a picture of a piece of wood sticking out of a refrigerator! Debris can hit people and kill them, walls can fall on them, or they can be lifted and dropped. That is why it is so important to have a plan, have a safe place to go, and have the proper precautions.
Every household should have a NOAA weather radio and know how to program and use it. If a severe thunderstorm warning is issued, be alert. Tornadoes can come even if no tornado warning is issued. If a tornado warning is issued, take shelter immediately. Do not waste time to verify that you are in danger, just take shelter. Put your shoes on, put babies in car seats, and put a helmet (bike, football, motorcycle, whatever you have) on every person. Preferably get underground or into an approved tornado shelter. If you can't, get to the lowest floor and into the center. Put as many walls between yourself and the tornado as possible. Get in, get down, cover up! Abandon mobile homes for a sturdy building or shelter. If you are caught in your vehicle, GET OUT and lie in a ditch. Cover your head. If you are far enough away to drive safely away, go at right angles away from the tornado.

The wind inside a tornado is so violent b/c of something called the 'conservation of angular momentum.'
Conservation of angular momentum works like this...
Air near the earth's surface is drawn into the storm by its strong updrafts.
The air is then stretched as it rises to the top of the storm.
This stretching causes the thunderstorm to rotate very fast and in some cases...a tornado is produced.
The conservation of angular momentum is the same kind effect you see when ice skaters pull their arms in toward their bodies and they spin faster and faster.
