← GeographyWhich outcome results when variations in thermohaline circulation modify the North Atlantic Deep Water formation process?
A)Altered distribution of marine biodiversity✓
B)Increased frequency of deep-sea earthquakes
C)Accelerated uplift of coastal landmasses
D)Intensified volcanic activity near Iceland
💡 Explanation
Changes in North Atlantic Deep Water (NADW) formation disrupt the global conveyor belt because salinity and temperature drive ocean density differences; this process known as thermohaline circulation, influences nutrient distribution. Therefore, marine species ranges change rather than crustal or mantel activity change.
