What causes wind?
• Wind is caused by the weight of
the air. Since cold air is heavier
than warm air, it has a greater
pressure and sinks. When this air
is heated up by the sun, it rises
and is replaced by new cool air
that rushes in. Usually, wind
blows from areas of high
pressure to areas of low
pressure.
