Explanation:

The Tornado is a meteorological phenomenon that consists of a whirlwind of wind produced as a result of an air rotation of great intensity and of little horizontal extension, which extends from the base of a mother cloud. The Fujita-Pearson scale and the so-called Enhanced Fujita Scale classify tornadoes according to the damage caused. The Enhanced Scale (EF) was a refinement of the old Fujita scale, using wind estimates and better damage descriptions; however, it was designed so that a tornado rated on the Fujita scale would receive the same numerical rank, and was implemented beginning in the United States in 2007. An EF0 tornado, the weakest on the scale, possibly damages trees but not structures, as long as that an EF5 tornado, the strongest, it can cause incredible devastation; it can rip buildings off their foundations, exposing them and even deform skyscrapers. The wind speed in a tornado can reach 500 km / h.
