What is a Tornado?

• A localized and demolishing windstorm happening
  over land by a funnel-shaped cloud going toward
  the ground.

How are Tornadoes Produced

• Tornadoes form when two masses of different
  temperatures and humidity meet. If the lower
  layers of the atmosphere are unstable, a strong
  upward movement of warmer air is formed. This
  starts to spiral as it rises, and intensifies.

Where and when do tornadoes occur?

• They are located in these following states IL OK
  AR MO KA IN NB IO TX. You know where these places
  are, but do you know when the tornadoes occur?
  They occur during cloudy, stormy weather and
  descend from severe thunderstorms as
  rapidly-spinning white funnels of cloud.

5
How are tornadoes classified?

• They are classified by the winds. That means that
  on a scale to measure the classification the wind
  determines how high, on the scale, the condition
  of the tornado.

6
Why are tornadoes considered severe weather?

• Thats because they are the most dangerous
  weather condition. They can kill lots of people
  and ruin property. But thankfully they are
  restricted in their range.
• Also the tornadoes can take off roofs from
  houses. Thats because the roof has high air
  pressure and the tornado has low air pressure and
  high air pressure all ways wants to get to low
  air pressure. So the makes the roof come off of
  the house.

Marble Questions

• If you do not have air pressure will it effect
  the tornado and why?
• How is this related to Bernoulli's principle?
