tornado causes and effects
Tornadoes develop more often in certain places than others. Areas like Florida and the Great Plains of the U.S. are prime spots for tornadoes because their hot summer air rises quickly and causes large and frequent thunderstorms.
The air gets thick and still. The wind stops. The sky turns green. And then you hear the siren warning you to take cover. If you've ever lived in a place where tornadoes occur, this is a familiar sequence of events. Tornadoes are spinning funnel clouds produced by thunderstorm clouds.
