Wind is caused by the uneven heating of the earth's surface. This produces regions that are warm where because the lower atmosphere gets heated it begins to rise, and it produces regions that are colder where the lack of heat causes the cold atmosphere to fall. Winds result from air being pushed away from those cold (high pressure) regions towards those warm (low pressure) regions. If the earth did not rotate the winds in both Northern and Southern hemispheres would blow directly towards the equator, since that's the warmest region of the planet. The rotation of the earth causes a more complex pattern to occur where you have wind belts - 3 in the southern hemisphere and 3 in the Northern hemisphere. Most of the United States is situated in the middle wind belt of the Northern hemisphere where winds blow primarily from west to east. So if you watch the weather channel you can often see these systems like storms moving towards the east coast.

The earth rotates, causing the uneven heating of the earth's surface this is called the Coriolis Effect. This causes a clockwise or counterclockwise weather pattern in either the northern or southern hemisphere.

Temperature and pressure are directly dependant on each other. Changing the temperature of the air will change the pressure in the air as well. When the air pressure changes, air will flow from an area of high concentration/pressure to low, which causes wind.

Here's a very simple answer that would probably work for a homework assignment....
When air in a certain area is warmed up it tends to rise. Cooler air then rushes in to replace the rising warm air creating wind.

When hot air and cold air mix, the hot air wants to go up and the cold air wants to go down. If they aren't already in this posistion then they have to push eachother out of the way and create wind and sometimes things like tornadoes and stuff.

heat produces energy. The first thing I thought of was the little "windmills " made of wood or brass, and they have candles that when burned, the heat from it produces "wind" that makes the blades turn.

Either the help we need is not justified so we feel it hard to ask for. When we are unable to have some thing we need or desire that is the right time to ask some one for help. Thank you.

warm air rises, cold air sinks. similar to how a tornado forms. plus it has to do with hi / low pressure systems
