Atmospheric Pressure and Wind Patterns

The video tutorial explains global air circulation, focusing on how air moves around the Earth. It covers the Earth's shape, latitudes, pressure belts, and the Coriolis effect. The tutorial also details global wind systems, including tropical easterlies, westerlies, and polar easterlies. The video concludes with a summary of air circulation and introduces upcoming topics on cyclones.

What happens to air as it rises and reaches the tropopause?

• It diverges

• It converges

• It descends

• It stays still
