Statement 2 is correct: Hadley cells are indeed formed due to the differential heating of the Earth&#8217;s surface. The equatorial region receives the most direct solar radiation, causing air to heat up, become less dense, and rise (convection). This rising warm air then flows poleward at high altitudes, cools, sinks around 30 degrees latitude, and returns towards the equator as surface winds (trade winds), completing the circulation loop.
