because hot air rises and cold air sinks.
it creates pressure changes, which make air particles move rapidly, hence we have wind.

Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface. It occurs at all scales, from local breezes generated by heating of land surfaces and lasting tens of minutes to global winds resulting from solar heating of the Earth. The two major influences on the atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect).
Given a difference in barometric pressure between two air masses, a wind will arise between the two which tends to flow from the area of high pressure to the area of low pressure until the two air masses are at the same pressure, although these flows will be modified by the Coriolis effect in the extratropics.

It is a complex combination of several factors. The air mass on earth is moved along because of the earth's rotation. This coupled with different air masses having different temperatures and therefore different pressures (ever hear the weather person refer to high or low pressure systems?) it causes these air masses to flow and move over the surface of the planet. Air flows like a fluid and can form currents like the jet stream--whose path is affected by those same temperature zones and pressure regions.

Cause Ted Kennedy talks too much
No serious, because of air pressure. Turn on a fan and do a simple wind experiment

Thermodynamics!
Differences of temperatures and pressures between different locations on the planet, come back to equilibrium by the way of air currents, the so called wind!

Because of pressure differentials in the atmosphere due to temperature variations of the different land and sea masses.

From the difference in air pressure. Usually from high pressure to low pressure.

Hot air rises, then turns cold, goes down, and pushes the air that gets in its way.

you can go to www.cosmeo.com and look at a video. I don't think you have to sign in to check it out.
