IPA: /ˌsɒlɪˈflʌkʃən/
KK: /sɑːlɪˈflʌkʃən/
The slow movement of soil or other materials down a slope, often occurring in areas where the ground is frozen.
After the heavy rain, solifluction caused the soil to slowly creep down the hillside.
Solifluction is formed from "sol" (from Latin *sol*, meaning sun) and "fluere" (meaning to flow). The term describes the process of soil flowing down a slope, often due to melting snow or ice, as if it were flowing under the influence of the sun's warmth.
Imagine soil 'flowing' ('fluere') down a slope under the warmth of the 'sun' ('sol') — that's how solifluction describes this natural process.
