Title: Tornadoes


1
Tornadoes
  • By Danny, Marcus and Josh

2
How do tornadoes form?
  • During the spring time, cool air rushes down from
    Canada.
  • This cool air meets the hot, dry air coming up
    from Mexico.
  • The two winds meet in an area known as Tornado
    Alley.
  • The warm air pushes below the cool air. Then
    tornadoes can occur.

3
How long can a tornado last?
  • Tornadoes can last from several seconds to more
    than an hour.
  • Most tornadoes last less than 10 minutes.

4
Where can tornadoes occur?
  • Tornadoes mostly occur in Texas, Oklahoma,
    Arkansas, Illinois, Kansas, Indiana, Missouri,
    Nebraska, and Iowa, but tornadoes can occur
    anywhere as long as the conditions for one have
    been met.

5
How far can a tornado travel?
  • A tornado can travel miles before tearing itself
    apart.

6
Safety Precautions
  • If on a road, never hide under an overpass if a
    tornado approaches.
  • Sometimes tornadoes will develop in areas in
    which no tornado watch or warning is in effect,
    so stay alert for changing weather conditions.

7
Interesting Facts
  • In 1992, a single tornado was on the ground in
    North Carolina for a record-setting 160 miles.
