Which outcome happens when increased glacial discharge alters North Atlantic salinity?

A)Weakened thermohaline circulation occurs
B)Increased rate of plate subduction
C)Formation of island arc volcanism
D)Increased equatorial ocean evaporation

💡 Explanation

Weakened thermohaline circulation occurs because decreased salinity reduces water density; therefore, sinking slows, disrupting deep water formation, rather than accelerating geological processes or evaporation rates.
