← GeographyWhich outcome follows the construction of structures on gradients affected by solifluction?
A)Increased downslope soil creep velocity✓
B)Decreased permafrost table depth
C)Enhanced ecosystem carbon sequestration
D)Reduced fine sediment accumulation
💡 Explanation
Increased downslope soil creep velocity occurs because permafrost thaw leads to increased water saturation and reduced soil shear strength thus solifluction accelerates after construction. Lower soil binding, rather than higher binding, results therefore increasing velocity.
