TORNADOES!!!!

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.

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

FUN FACTS AboutTornadoes!!
