How does the uneven heating of Earth create global winds?

Warm air rises at the equator and moves toward the poles. At the poles, the cooler air sinks and moves back toward the equator.

The uneven heating of Earth's surface produces wind because the air temperature and air pressure are different. The difference in the air causes the air to a lower pressure. The movement of this wind. Uneven heating of the Earth's surface produces air masses of different temperatures. Cold air sinks, forcing warm air to rise.
