← GeographyWhich outcome occurs when an oceanic plate undergoes complete subduction?
A)Uplift via isostatic rebound occurs✓
B)Widespread formation of strike-slip faults
C)Accelerated rate of seafloor spreading
D)Decreased frequency of strong earthquakes
💡 Explanation
Uplift via isostatic rebound occurs as the removal of the dense oceanic plate allows buoyancy due to the reduced load; this process is called isostasy because the crust 'floats' in equilibrium. Therefore, uplift happens rather than other fault formations, or decreased earthquake activity because subduction processes drive fault behavior.
