What is wind? Wind is moving air. We can’t see the wind but we can see and feel the effects of the wind ass it blows things around. Wind is created by differences in air temperature. ature. The sun heats up the land d and, as the land gets warmer, the air above the land warms up too. Warm air rises and colder air moves below it. This flow of moving air is wind. The bigger the difference in air temperature, the faster the air moves and the stronger the wind blows.

The higher up mountains you go, the windier it gets, because fewer things like buildings or trees get in the way to slow down the wind. In some places, it can get very windy out at sea because the ocean is flat and the wind d can flow freely across it and build up speed.
