← GeographyWhich outcome predominantly dictates annual global heat circulation?
A)Thermohaline overturning and density variations✓
B)Seasonal variations insolation earth orbit
C)Prevailing wind patterns surface currents
D)Latitudinal changes evaporative heat flux difference
💡 Explanation
Global heat regulation arises from thermohaline circulation because density gradients influence water movement; therefore, differential water temperatures emerge at various depths, rather than solely relying on wind or radiative effects.
