Which resulting ground feature indicates intense solifluction due to thawing permafrost on gentle alpine slopes?

💡 Explanation

When permafrost thaws, the active layer undergoes solifluction because the saturated soil flows downslope due to gravity above the impermeable frozen ground, forming small terraces along the contours. Therefore terracettes are the result, rather than eskers, kettle lakes or drumlins which are formed from glacial meltwater or ice deformation.
