← GeographyWhich outcome regarding water salinity occurs when glacial meltwater mixes with submarine groundwater discharge near coastal aquifer systems?
A)Formation of dense saline wedges
B)Increased stratification within estuaries✓
C)Calcium carbonate mineral precipitation
D)Upwelling events near saltwater aquifers
💡 Explanation
Increased stratification occurs because the mechanism of buoyant convection prevents mixing with the denser saline groundwater; therefore a surface layer of fresher water exists rather than a uniformly mixed saline profile near the coast.
