what drives the circulation of air in the atmosphere?
a. Conduction
b. Convection
c. Condensation
d. Evaporation
b. Convection
The correct answer is b. Convection.
Convection is the main process that drives the circulation of air in the atmosphere. It occurs when warm air rises and cool air sinks. As the Sun heats the Earth's surface, the air near the surface becomes warm and begins to rise. This rising warm air creates an area of low pressure at the surface. In response to this, cooler air from higher altitudes moves in to replace the rising warm air, creating an area of high pressure. This movement of air from high pressure to low pressure generates wind and leads to the circulation of air in the atmosphere.
