← GeographyWhich outcome occurs when tectonic plate movement constricts oceanic straits?
A)Amplified global thermohaline circulation✓
B)Decreased abyssal plain sedimentation
C)Increased coastal evaporite formation
D)Reduced magnetic anomaly stratification
💡 Explanation
Constricting straits intensifies salinity gradients initiating and accelerating thermohaline circulation due to increased density differences. Therefore, circulation is amplified, rather than other sediment or magnetic effects which arise from unrelated processes because these processes depend on other factors.
