← GeographyWhich risk increases when extensive loess deposits accumulate?
A)Reduced carbon sequestration efficiency
B)Increased susceptibility to slope instability✓
C)Enhanced geothermal gradient formation
D)Decreased mineral weathering rates
💡 Explanation
Loess deposits, composed of loosely packed silt, become saturated during rainfall, triggering liquefaction; therefore, slope instability risk increases rather than creating gradient formation, because the water weakens the deposit's cohesive strength causing mass wasting events.
