Question

Explain how convection cells are formed at different latitudes. Discuss the role of low-and high- pressure areas in convection in your response.

Answer 1

Because more solar energy hits the Equator, the air warms and forms a low pressure zone. The cool air is dense, and when it reaches a high pressure zone it sinks to the ground. The air is sucked back toward the low pressure at the Equator. This describes the convection cells north and south of the Equator.

Within the troposphere are convection cells . Warm air rises, creating a low pressure zone; cool air sinks, creating a high pressure zone. .When cool air descends, it warms. Since it can then hold more moisture, the descending air will evaporate water on the ground.
