Tornadoes
This is an example of how much devastation a tornado can cause. This is what was left of Tuscaloosa, Alabama after a tornado disaster in 2011.
A tornado is a moving funnel of rotating air that is formed from supercell thunderstorms. Often, tornadoes have wind speeds lower than 100 miles per hour. A tornado can move approximately 10 to 20 miles per hour. The U.S usually can have about 12 hundred tornadoes each year. In the southern hemisphere tornadoes usually rotate in a clockwise direction. However, tornadoes rotate in a counterclockwise direction in the northern hemisphere. Also, tornadoes are able to cause about 100 deaths each year in the U.S. The most affected part of the U.S is the tornado alley. Also, tornado warnings usually take about 13 minutes to come and 70% of the time, it is a false alarm. The most violent tornado in the U.S was an invisible tornado, it was known as the Tri-State tornado. It created about a thousand injuries and over 700 deaths. It went through Illinois, Missouri and Indiana at 60 to 70 miles per hour. Based on this information, we could tell that tornadoes are really dangerous and they are as dangerous as they sound. Next, you'll see the steps of tornado formation.
