Which topographic outcome occurs when increased surface soil moisture triggers solifluction?

A)Formation of lobate debris sheets
B)Development of esker ridge systems
C)Increased dissolution causing karst topography
D)Deposition forming alluvial fan deposits

💡 Explanation

Lobate debris sheets form because increased moisture decreases soil shear strength, which increases the rate of solifluction, leading to downslope movement, therefore soil accumulates into lobe-shaped formations, rather than deposition by fluvial systems forming alluvial fans.
