← GeographyWhich outcome results when joints and bedding planes weaken?
A)Accelerated stack formation via coastal erosion✓
B)Increased plankton blooms, oxygenating sediment
C)Glacier density increased from densification
D)Reduction in isostatic rebound magnitude
💡 Explanation
Joints and bedding planes weaken due to weathering, accelerating coastal erosion because hydraulic action widens the pre-existing fractures, and wave action undermines cliffs, therefore forming sea stacks rather than other geological uplifting features.
