because the earth moves under my feet under my feet and goes round and round,...............no really!

by definition, wind is caused my horizontal pressure differences. there are many factors which affect how the pressure changes: Air Mass movement, Temperature changes, convective and orographic movement of air.
if you want to have a simple experiment at home, turn on your shower very hot and close your curtains. within a few minutes you will notice the inner lining being "sucked' into the shower. the reason is that the hot water is causing the air inside the shower area to rise, therefore creating a deficit or low pressure inside the shower (or tub). the air surrounding the shower is at a higher relative pressure and it wants to move in to replace the air which is "missing" from the area in the shower. if you move one end of the curtain a little bit to allow some of the air in the shower you will feel a slight rush of "wind" which will continue until the shower is turned off and the pressure is equal.

The earth spins very fast and due to this air currents start to form, around the equator then moving up to the poles
tides also cause wind
when you go by a beach have you ever noticed that it is windyer that places furher away?

Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface.

Wind comes from air molecules moving from areas of High pressure systems to low pressure systems. The air tries to create a system of equilibrium with its self, so it moves around trying to do it.

Wind is air moving from a heated area to a cooler area.

the sun warms the earth which warms the air, which rises and makes room for colder air to rush in to replace it thus creating a wind. It has all to do with cold air replacing warm air because of different temps.

Actually, the humorists who are obsessed with f@rts do unwittigly provide the answer. When you need to f@rt, the pressure in your bowel is greater than outside, or if you are a real f@rtiste, you can build that pressure yourself.
Anyway, this shows how air moves from high pressure to low pressure.
