← GeographyWhich effect intensifies when coastal upwelling brings nutrient-rich deep water to the surface during increased solar radiation?
A)Harmful algal bloom expansion✓
B)Ocean acidification reduction
C)Deep-sea methane hydrate release
D)Sea ice formation acceleration
💡 Explanation
When nutrient-rich deep water is brought up by coastal upwelling, increased solar radiation causes phytoplankton to proliferate rapidly, leading to harmful algal bloom expansion. Therefore algal blooms intensify rather than any other listed outcome, which requires different environmental triggers like specific ocean chemistry changes.
