Answer 1

in air the molecules are very loosly packed so tht the air moves....

Answer 2

~Pressure differences in the atmosphere cause the air to move. Winds generallymove from the poles to the equator because air moves from areas of high pressure to areas of low pressure. The pattern of pressure is not as simple as the diagram above. As warm air rises, it begins to cool and eventually stops rising.
