Which type of deformation occurs to surface structures built on slopes undergoing solifluction?

💡 Explanation

When slopes undergo solifluction, the active layer thaws and slowly flows downslope, causing downslope creep and deformation of overlying structures because of the pressure exerted by saturated soil. Therefore, tilting occurs, in contrast to uniform subsidence, cracking, or shearing, which result from other soil mechanics issues.
