4. Where Do Tornadoes Form?

This area is known as “Tornado alley” Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Louisiana, Mississippi, Missouri, Nebraska, Oklahoma, South Dakota, and Texas. This area is known as “Tornado alley”

6. How Tornadoes Form

7. Step 1 First, two patches of air moving from opposite directions collide, the warm air on the bottom and the cool air on top First, two patches of air moving from opposite directions collide, the warm air on the bottom and the cool air on top

8. Step 2 Second, as the warm air rises the two patches begin spinning side to side and up and down Second, as the warm air rises the two patches begin spinning side to side and up and down

9. Step 3 Third, because tornadoes occur during storms, air is already moving around and if the air gets close to the ground and moves up it pulls the already spinning air upwards. This is called an “up-draft” Third, because tornadoes occur during storms, air is already moving around and if the air gets close to the ground and moves up it pulls the already spinning air upwards.
