The tornado is one of the most powerful winds on the earth. The speed of a tornado is more then three hundred miles per hour.
Many tornadoes are as tall as several hundred yards or meters.
Tornadoes have caused lots of death and destruction. Tornadoes are just rotating clouds shaped as a funnel. The way a tornado starts is first a dark cloud forms then the cloud forms a large spinning funnel. Then it stretches toward the ground. If the tornado touches the ground, it collects dirt and forms a huge dust cloud around it and destroys everything that gets in the way.
