Choose the correct answer to each of the questions from 1 to 5.          Tornadoes are giant rotating columns of air. They form in thunderstorms when there is a great difference in the temperature and humidity of the lower and upper atmosphere. They can be very dangerous and very destructive.         There are different varieties of tornadoes. They can be very big or small. Some tornadoes are only a few feet across and others can travel across an entire state. Tornadoes stretch from the ground high into the sky. Usually, people rate them from F0 to F5, F5 being the most dangerous with wind speeds of around 261- 318 miles per hour. They are a very violent force of nature and can lay whole towns completely flat.        Tornadoes can happen all over the world but a lot of them happen in the central United States in a region called Tornado Alley.
