← GeographyWhich outcome occurs from Antarctica's density-driven water circulation?
A)Nutrient-rich waters rise from depths✓
B)Increased methane release from clathrates
C)Enhanced coastal erosion near glaciers
D)Reduced salinity in surface waters
💡 Explanation
Upwelling elevates nutrients because thermohaline circulation drives dense, nutrient-rich water upwards due to density differences. This upward flow supports marine ecosystems worldwide; therefore, a biological bloom will happen, rather than altering glacial erosion.
