Wind

Wind, the movement of air, is a meteorological phenomenon that plays an integral part in activities ranging from the production of electricity to the creation of myth. It is one of the natural elemental forces of the world. Wind can be felt, and its effects can be observed and measured, but wind itself cannot be seen. It is an invisible force that assists in weather change, and provides power to machines that take advantage of it.

There are many myths and stories behind the power of wind; it seemingly comes from nowhere and is recognized. Polytheistic religions often attributed the power of wind to a deity, or a servant.

Causes

Wind is actually the motion of air, produced by change in heat on the earths surface. As different parts of the Earth heat up, the air in those parts rises as the cooler parts cause air to sink. This change in temperature generates the motion of air.
