These differences in temperature set in motion a restless movement of air and water in great swirling, churning currents to distribute heat energy from the Sun across the planet from the warm Equator to the cold Poles. When air in one region is warmer than the surrounding air, it becomes less dense and begins to rise, drawing more air in underneath. Elsewhere, cooler denser air sinks, pushing air outward to flow along the surface and complete the cycle.
