The sun heats the earth unevenly, creating regions of high pressure and low pressure. Air from the high pressure regions tends to flow to the low pressure regions. Therefore, the wind blows.

We are heated by the sun....not all areas of the Earth receive the same amount of heat....the equator for instance, receives more than most and coversely the poles the least amount. As hot air rises at the equator, the space has to be filled by incoming air, usually travelling up or down from either the north or south poles, this is felt in the form of wind....also, large storms generate low pressure and so again, air is sucked in to fill the void. This coupled with the rotation of the Earth causes the wind to have a slant to it...it is known as the Coriolis effect....a good example are the famous SE Trade winds, used by ships many years ago because of their consistency....without wind we would be in deep trouble as many of our heated areas would then overheat and an imbalance would create extremely violent storms...possibly unsurvivable by man..you may not like it but you would definitely not survive without it ...learn to love your winds

well, there are many reasons, 1) the wind blows becoz of temperature differences like during the night the wind is much cooler and once the sun starts to heat up the earth the wind rises and that couses motion. this is happening all across the world all the time so there is a continuous motion of wind. 2) the earths rotation, since earth it self rotates that couses motion in the waters of the oceans and that in turn causes the wind to move. 3) the gravitational influnce of the moon... and so on and so forth.

The air pressure is different in different places. Nature wants to even out any change in pressure, causing air to flow from areas with higher pressure towards areas with lower pressure. This airflow is wind.
(The air pressure not being the same all over the world has to do with the fact that the sun heats the earth unevenly.)
But nothing is ever as simple as you would wish. The air flow from higher towards lower pressure is complicated by the rotation of the earth, and other factors as well. But the fact remains - if there were no pressure differences, there would be no wind.

As you know, warm air rises, so in areas where the air gets warmer, over cities for example, the air rises.
This leaves a "hole" in the air, so cooler air from outside moves in to fill the gap.
It is a bit simplistic, but that is basically the reason in a nutshell.

The blow is caused by the contrast of hot and cold pressure.

the sun heats up different surfaces at differing rates (land, sea, rocks, vegetation); those surfaces radiate the heat back out at different rates; warm air masses rise; cooler air masses sink thus creating a verticle flow; the rotation of the earth adds horizontal flow; & there are, of course, others factors......but basically, you get the idea.....
