how does the sun cause the wind to blow on earth?

Answer 1

It heats up the atmosphere in the day time and at night when there is no sun, heat rises from the ground creating disturbances in the atmoshpere, aka wind. The same applies to cold air sinking from the upper layers of the atmosphere to the ground.

Answer 2

The rays of the sun cause the air to warm up, creating what are known as "convection cells". These convection cells cause air to circulate, creating differences in temperature and pressure. When you feel a sea breeze during the summer, it is because the there is a convection cell generated as the air over the beach rises from the hot sand and sinks over the cooler water, creating a wind effect. Try this little experiment if you want to see what a convection cell looks like:

1. Obtain a pyrex glass bowl and fill it with water.
2. Place bowl with water on a gas burner and let it come to a boil
3. When water starts to boil, add a few drops of iodine and watch watch happens to the iodine as it traces out the convection cell in the boiling water

Basically, the gradient in temperature (temperature distrubution) throughout the water causes differences in pressure which starts to create the currents. This is the same thing that happens in our atmosphere and generates wind.

Answer 3

Sun shines on the earth's surface and some spots heat up faster than others. cities with a lot of concrete and little vegetation heat up faster than forests. The heated surface heats the air above it. As the air heats, it expands, becomes lighter and rises. When that air leaves the surface some air has to come from somewhere to replace it--otherwise we would have a place with no air and couldn't breathe. Nature doesn't like a vaccuum. (Heard that before?) so. . . surrounding air moves in to take the place of the rising air. Moving air...we have a name for that--wind.

Answer 4

"Hot air rises". Also, heated water causes water-vapor to rise from the surface of the water, forming clouds above, and winds circulating around the water vapor. Almost all (or all) hurricanes are formed by water vapor rising from the heated seas and oceans.
