← GeographyWhich outcome occurs when tectonic plate subduction ceases?
A)Isostatic rebound uplifts the continental crust✓
B)Increased mantle upwelling near the trenches
C)Magnetic field reversal events increase rapidly
D)El Niño frequencies and intensities increase
💡 Explanation
Isostatic rebound occurs because the removal of the subducting plate's weight allows the continental crust to浮上, according to Archimedes' principle. The continental crust slowly returns to equilibrium; therefore rebound, rather than changes in mantle plumes, magnetic fields or El Niño dynamics are observed.
