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

💡 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.

• Which risk increases when accelerating thaw of sub-sea permafrost releases methane hydrates?
• Which risk increases within a periglacial environment exhibiting significant solifluction?
• Which outcome occurs when tectonic stress exceeds bedrock strength?
• Which outcome occurs when stress rapidly accumulates along a transform plate boundary below a large artificial reservoir?
• Which outcome results when persistent winds initiate deflation of poorly-vegetated playas?
• Which consequence results when extensive deflation occurs in playas?
