← GeographyWhich outcome occurs when isostatic equilibrium shifts post-glacially for islands?
A)Increased incidence of submarine landslides✓
B)Accelerated growth of mangrove forests
C)Decreased thermohaline circulation locally
D)Reduced coastal upwelling intensity region-wide
💡 Explanation
An isostatic rebound alters submarine slopes because a shift in the equilibrium causes increased stress on accumulated sediments, which triggers mass wasting; therefore submarine landslides become more common, rather than mangrove spread, circulation variance, or distant upwelling influences.
