Which mass wasting process causes lobate terraces to form down slope in arctic environments?

💡 Explanation

When subsurface permafrost thaws, solifluction occurs because the active layer becomes saturated and flows downslope due to gravity, commonly forming lobate terraces. Therefore solifluction creates these terraces, rather than creep, landslides, or mudflows, all whom require alternative water inputs on differing geologic layers.
