← GeographyWhich mechanism causes increased marine productivity when deep ocean water rises to the surface?
A)Nutrient transport through upwelling✓
B)Thermal energy release via convection
C)Increased salinity via evaporation
D)Wave propagation across pycnoclines
💡 Explanation
When deep ocean water rises, upwelling occurs because density differences and wind patterns displace surface water, bringing nutrient-rich water upwards and enhancing phytoplankton growth. Therefore, nutrient transport results, rather than energy release, salinity increase or wave propagation, which require different processes.
