9. 9. Definition: A tornado is aviolent, dangerous, rotating column of air that is incontact with both the surface of the earth and acumulonimbus cloud or, in rare cases, the base of acumulus cloud.
10. 10. How do tornadoes form?
11. 11. 1. Air starts to rotate when the wind is at 2 different altitudes,blowing at different speeds.2. Faster spins (rotates) make a funnel cloud.3. The funnel cloud rotates and touches down. Rain and hail fromthe storm makes the funnel touch the ground.1 2 3
12. 12. How do we know how strong a tornado is?
13. 13. A tornado is rated on a Fujita Scale, rating a tornado between F-0 to F-5 (F-0 meaning not bad, F-5 meaning very bad)They rate based on the tornadoes wind speed as well as damage done.
14. 14. F-0 to F-1 tornadoes
15. 15. “F-0 to F-1 tornadoes can collapse chimneys, tossmobile homes off their foundation, and have thestrength to push cars off the road.”
16. 16. F-2 to F-3 tornadoes
17. 17. “Tornadoes can tear away roofs and liftand toss heavy cars.”
18. 18. F-4 to F-5 tornadoes
19. 19. “F-4 to F-5 tornadoes have the strength to pick up and carryentire buildings an entire distance, toss steal beams, andcrunch cars. These tornadoes are very rare but are responsiblefor 2/3 of tornado deaths in the United States every year.”
21. 21. NEAT FACTS!!!!1. They can go 300mph!2. Their damage paths can be one mile wide, and up to 50 miles long.3. Each year on average 1000 tornadoes occur!4. We are safer in a room with no windows when a tornado occurs.5. The sound of a tornado siren (click on the siren icon) Siren
22. 22. Now that you have learned all about tornadoes and whythey occur, you now can go home and tell your familieswhat you should do if a tornado occurs. You can tell themwhy they occur and how dangerous they can be.
23. 23. QUIZ TIME!!!It’s time to check what you have learned 
