← GeographyWhich mechanism causes global surface temperature redistribution by thermohaline circulation?
A)Latent heat transfer from evaporation
B)Net sensible heat flux via advection✓
C)Longwave radiation emission and absorption
D)Seasonal mixing by tidal forces
💡 Explanation
When thermohaline circulation operates, sensible heat is transferred because water masses of differing temperatures move from the equator, where they are heated, towards the poles, redistributing heat. Therefore sensible heat flux causes temperature changes, rather than latent heat, radiation, or tides, which have distinct roles in ocean heat balance.
