Tornado!

One of nature’s strongest winds, tornados can reach winds in excess of 300 mph. In an average year in the United States, up to 800 tornadoes will be recorded (That’s a lot!). Each of these tornadoes are placed on the Fujita scale by how much damage they cause. An F0 tornado causes little damage but mainly to trees. However an F5 tornado, the strongest and most powerful of tornadoes, causes the most damage. An F5 will destroy everything in its path, flattening homes and buildings and moving them off their ground foundation.




So, how does a tornado form and work?

Tornadoes are produced when warm and cold air collide with one another. Thunderstorms form in warm, moist air and when it meets the colder air as the storm is moving, the two mix together making perfect, yet possibly devastating conditions, for tornadoes to form.
