← GeographyWhich topographic effect does accelerated solifluction primarily generate on moderate slopes?
A)Terracettes or 'turf-banked' steps✓
B)Deep V-shaped valley incision
C)Extensive sand dune formation
D)Honeycomb weathering patterns
💡 Explanation
When saturated ground freezes and thaws on moderate slopes enhanced solifluction occurs, creating downslope soil creep that forms repeating terracettes because differential movement accumulates soil at step edges. Therefore terracettes result, rather than valley incision, dunes, or patterns requiring different geomorphic processes.
