Which factors or processes drive the movement of air in Hadley cells?

-Cool, dry air falls towards the surface of the Earth, where increased air pressure causes adiabatic heating, resulting in warm, dry air.
-Heated surface water rises into the atmosphere as water vapor, until adiabatic cooling causes it to condense and fall back to the Earth as rain.
-Warm air is more dense than cool air, giving it a high capacity for retaining water vapor, which allows air to carry water vapor into the atmosphere.
-The Sun's rays hit the Earth at an oblique angle, causing the light to hit a large are of the Earth, which rapidly heats the air and surface waters.
-Warm, humid air displaces cool air in the atmosphere and pushes cool air outward from the equator to the north and south.

Final answer:

The movement of air in Hadley cells is primarily driven by unequal heating of large masses of air and the rotation of the Earth. The water cycle also plays a role in the movement of air in Hadley cells.

Step-by-step explanation:

The movement of air in Hadley cells is primarily driven by unequal heating of large masses of air which creates air movements. This leads to the flow of hot air from the tropics to the poles and the flow of cold air from the poles toward the tropics. Another driving factor is the rotation of the Earth, which causes the observed easterly flow of air in the northern hemisphere.

Additionally, the water cycle plays a role in the movement of air in Hadley cells. When the Sun heats the water on the Earth's surface, it evaporates and rises into the atmosphere as water vapor. As the water vapor cools, it condenses and falls back to the Earth as precipitation, completing the cycle.
