Earth's surface winds generally blow from regions of higher
air temperature toward regions of lower air temperature
air pressure toward regions of lower air pressure
latitudes toward regions of lower latitudes
elevations toward regions of lower elevations
Wind is caused mainly by air-pressure differences that result from
uneven heating of Earth's atmosphere
absorption of ultraviolet radiation by Earth's landmasses
radiation of heat from Earth's landmasses to water bodies
rotation of Earth on its axis
