HOW TORNADOES ARE FORMED
A tornado is formed when warm rising air collides with cold air rushing to the ground, then the rotating begins. The air spins at an incredible speed, so fast that it makes a very loud noise. The hollow center has very low air pressure.
Types of tornado
There are many types of tornado and they all look very different. The supercell (long lasting) tornado is the most violent tornado. Born in a thunder storm and spinning at a massive 200 mph (miles per hour)! A land spout is weaker than a supercell and a land version of a water spout. It forms on the edge of
rain cooled land. A water spout is pretty but harmless. It usually forms over warm ocean water. Gustnadoes are weak and short, often forming in the front of a thunder storm. It will not cause much damage. A dust devil is harmless and os the only tornado that does not form in a cloud. It is the weakest tornado we know of. The rarest tornado of them all is the fire whirl. Short lasting, but very pretty. They form by tornadoes getting to close to bush fires, and the tornado catches fire! The reason they are so short lasting is the fire goes out soon after it forms.

Effects on the people and the land
Tornadoes demolish towns and cities making it look like they have exploded. In Missouri (USA) on the 18th of March in 1925 a tornado tore through 10 towns destroying 2 thousand and ten homes and injuring many people. But some tornadoes don't always have such catastrophic effects. One tornado picked up a crate of eggs and carried it 500 feet away and put it down and not a single egg was broken. Another tornado picked up a carriage with a sleeping baby in it, carried it 800 feet and put it down with out even waking the baby.
