← GeographyWhich outcome results when isostatic depression overwhelms fjord bedrock?
A)Increased submarine landslide frequency✓
B)Accelerated sea ice formation.
C)Decreased marine biodiversity occur
D)Reduced coastal erosion rates
💡 Explanation
Increased submarine landslide frequency occurs because isostatic depression weakens bedrock, triggering increased gravitational shear via gravitational loading rather than glacial rebound. This leads to slope failure whereas bedrock integrity would prevent it and related hazards.
