Wind is caused by the movement of air.

When you use a fan, you make wind!

In the natural world, wind can take on many different forms, from a pleasant breeze to a devastating hurricane.

So, how are these movements of air formed?

A mass of air moves due to the temperature: it rises when it’s hot. Once at the top, it cools down, becomes heavier and starts to drop.

When a mass of air moves, another one takes its place. This movement is… wind!
