7. Today, students, you are going to use the computers to go
through a PowerPoint about tornadoes. After you complete the
PowerPoint, you will then take a 10 question quiz over the
material presented in the PowerPoint.
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.
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.

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.
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.”
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.
