← GeographyWhich outcome occurs when increased ice sheet melt accelerates isostatic rebound?
A)Reduced local gravitational field strength✓
B)Increased frequency of glacial earthquakes
C)Decreased albedo due to darker exposure
D)Altered regional effective elastic thickness
💡 Explanation
A reduced gravitational field strength can occur because isostatic rebound causes redistribution of mass and, therefore, a change in gravitational pull during glacial isostatic adjustment, rather than increased quake activity. Mass redistribution, rather than darker surfaces causes measurable changes in the gravitational field.
