← GeographyWhich outcome sharply increases when newly formed volcanic islands experience high rainfall?
A)Accelerated chemical weathering✓
B)Increased magnetic inclination
C)Elevated geothermal flux
D)Enhanced biogenic sedimentation
💡 Explanation
Accelerated chemical weathering occurs because high rainfall on volcanic islands initiates hydrolysis, dissolving volcanic rock rather than changing its magnetic field or geothermal activity. Therefore, weathering increases, rather than slowing down under normal circumstances.
