← GeographyWhich outcome arises when tectonic uplift decreases a lake's catchment area and inflow?
A)Salinity increase via evaporative concentration✓
B)Eutrophication from sediment accumulation
C)Acidification by increased sulfate influx
D)Turbidity reduction causing thermal stratification
💡 Explanation
When uplift reduces catchment area and inflow, a lake's water budget becomes dominated by evaporation because the input of freshwater decreases significantly, concentrating dissolved salts. Therefore salinity will increase significantly, rather than eutrophication, acidification, or turbidity reduction which rely on different biogeochemical processes.
