← GeographyWhich consequence is amplified when Antarctic ice sheet melt increases due to albedo effect?
A)Oceanic thermohaline circulation slowdown✓
B)Stratospheric ozone layer depletion
C)Atmospheric methane concentration decrease
D)Global average sea surface salinity increase
💡 Explanation
When ice sheet melt increases, the albedo effect causes less solar radiation to be reflected because the reflective ice surface is reduced, leading to further warming of the ocean. Therefore, the thermohaline circulation slows down because the influx of freshwater reduces the density, interrupting sinking, rather than ozone depletion, less methane, or salinity increase, which depend on other processes.
