Wind

Wind

is

created

when

air

moves

from

an

area

of

high

pressure

to

an

area

of

low

pressure.

If

people

know

which

direction

the

wind

is

blowing,

they

can

often

figure

out

what

type

of

weather

is

coming.

Wind

vanes

and

wind

socks

indicate

wind

direction.

A

wind

vane

twirls

on

a

post,

and

an

arrow

on

it

points

in

the

direction

the

wind

is

blowing

from.

A

wind

sock

shows

the

direction

the

wind

is

heading.

One

end

is

tied

to

a

post,

and

the

loose

end

is

carried

outward

by

the

wind.
