← GeographyWhich outcome occurs when the isostatic equilibrium of a coastal region experiences glacial retreat?
A)Increased rates of marine terrace formation✓
B)Decreased subduction zone volcanic activity
C)Reduced sediment erosion from river systems
D)Diminished strength of thermohaline circulation
💡 Explanation
Higher rates of terrace formation will occur because the isostatic rebound allows for uplift while increased wave action leads to increased erosion. The wave abrasion mechanism carves away previously submerged topography, therefore marine terraces will form, rather than subdued volcanic activity.
