Wind Power
Can you remember blowing
on a pinwheel? The harder you
blew, the faster it spun.
Imagine thousands of people
blowing on that same pinwheel.
What would happen?
All of those people might
create a very big wind.
But even if they blew their
hardest, the wind they made
would not come close to the
power of a tornado or hurricane .
Tornadoes and hurricanes are
the biggest winds of all!
Tornadoes
Have you ever watched
water go down a drain? It
becomes a whirlpool .
What Is It?
A whirlpool is wide at
the top and narrow at
the bottom. It is open
down the middle. Water
in a whirlpool drains
down, spinning around
and around.
A tornado is like a whirlpool,
only it is much bigger and made
of air instead of water.
Tornadoes are powerful. If
you have seen them in movies,
you have some idea of what
tornadoes can do.
They can knock down big
buildings. They can blow away
cars and trees as if they were
feathers.
How Tornadoes Happen
Tornadoes come from strong
winds, powerful thunderclouds ,
and warm and cold air.
tornado
If warm and cold air meet
in a storm, they can form a
whirlpool of air. When the
whirlpool swirls fast enough, it
becomes a tornado.
Debris (duh-BREE)
is bits of earth and
other things that
have been broken
and destroyed.
A tornado reaches down
from a thundercloud like a
swirling, gray snake. It picks up
debris from the ground below.
The tornado swirls and hops
along the ground. It follows the
path of the thundercloud.
