Outline for an informative speechYour nameTornadoPurpose: to inform the public about tornadoes.Thesis: To better understand tornadoes, it is important to explore the causes that cause them to develop, how researchers classify the types of tornadoes, and strange events that may be associated with tornadoes. Organizational model: Current affairsI. IntroductionA. Warning: What can push cars through the air, tear apart ordinary homes, pluck chickens, and travel at speeds over 60 mph? B. Significance: Illinois sits on the edge of what tornado researchers call tornado alley. This is the area of ​​the country that receives the most tornadoes each year. According to a 1995 brochure distributed by the National Oceanic and Atmospheric Administration (NOAA), an average of 27 tornadoes occur in Illinois each year. Additionally, nearly 5 people die each year in Illinois due to tornadoes [AID]. In fact, according to Tornado Project Online!, a website hosted by a company that compiles tornado information for researchers, the deadliest tornado in U.S. history occurred in Murphysboro, Illinois. In 1925 a violent tornado killed 234 people in this southern Illinois city.C. Credibility: I grew up in the heart of Tornado Alley and have been interested in this weather phenomenon for a long time. Additionally, I am a trained weather observer for the Bloomington/Normal.D Civil Defense Agency. Thesis: To better understand tornadoes, it is important to explore what causes them to develop, how researchers classify tornado types, and strange events that may be associated with tornadoes.E. Preview: So, let's examine the causes of tornadoes, analyze the types of tornadoes, and explore some of the oddities associated with tornadoes. Transition: Initially we will look at the causes of tornadoes.II. BodyA. What causes tornadoes?1. According to the USA Today Tornado Information website, a tornado is a "violently rotating column of air in contact with the ground and hanging from a thunderstorm." Therefore, thunderstorms are the first step in creating a tornado.2. The USA Today Tornado Information site also indicates that there are three key conditions for thunderstorms to form.a. First, humidity in the lower to mid levels of the atmosphere.
