- 9. Definition: A tornado is a violent, dangerous, rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
- 10. How do tornadoes form?
- 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 from the storm makes the funnel touch the ground. 1 2 3
- 12. How do we know how strong a tornado is?
- 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. F-0 to F-1 tornadoes
- 15. “F-0 to F-1 tornadoes can collapse chimneys, toss mobile homes off their foundation, and have the strength to push cars off the road.”
- 16. F-2 to F-3 tornadoes
- 17. “Tornadoes can tear away roofs and lift and toss heavy cars.”
- 18. F-4 to F-5 tornadoes
- 19. “F-4 to F-5 tornadoes have the strength to pick up and carry entire buildings an entire distance, toss steal beams, and crunch cars. These tornadoes are very rare but are responsible for 2/3 of tornado deaths in the United States every year.”
- 20. Now let’s learn… FUN FACTS About Tornadoes!!
- 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. Now that you have learned all about tornadoes and why they occur, you now can go home and tell your families what you should do if a tornado occurs. You can tell them why they occur and how dangerous they can be.
