Is it true that solifluction is the fluctuation of temperature in the soil

Answer 1

No, solifluction is not the fluctuation of temperature in the soil. Solifluction is actually a type of mass wasting or slope movement where water-saturated soil moves slowly downhill over a frozen layer of ground. This typically occurs in permafrost regions where the upper layer of soil thaws during the summer but remains frozen beneath, creating a slippery layer that allows the overlying soil to flow downslope. Temperature fluctuations in the soil can contribute to solifluction by influencing the freeze-thaw cycle, but solifluction itself is not caused by temperature fluctuations.
