← GeographyWhich outcome occurs when crustal subduction ceases at depth?
A)Isostatic rebound initiates uplift.✓
B)Oceanic salinity increases extensively.
C)Mantle convection temporarily halts.
D)Increased hydrothermal vent activity.
💡 Explanation
Uplift initiates due to decreased density at depth, and isostatic rebound occurs because material removed leads to an upward pressure, rather than salinity increases dependent on evaporation, or related mechanisms.
