Which consequence results when permafrost thaws excessively after deforestation?

💡 Explanation

Deforestation can expose permafrost, leading to thawing and increased soil moisture which weakens the soil’s shear strength. Because increased moisture and reduced strength facilitate soil creep downslope via solifluction, widespread slope destabilization occurs, therefore resulting in mass wasting rather than the slower weathering or fluvial processes.
