← GeographyWhich flow change results from increased glacial runoff?
A)Deep water formation slows down✓
B)Surface gyre circulation speeds up
C)Upwelling events become more frequent
D)El Niño events become less intense
💡 Explanation
Slowing of North Atlantic Deep Water production occurs because increased freshwater input reduces surface water density, inhibiting _convection_, therefore hindering sinking and deep water formation, rather than increased gyres or upwelling events, which depend on wind or other factors.
