A process of slow, downslope movement over a long period of time.

When gravity moves the soil mantle downhill at rates too small to observe.

The gradual and steady downhill movement of soil and loose rock material on a slope.

The movement of large soil particles along the soil surface by wind.

the gradual downhill slide of weathered material; the slow, gradual movement of a hill's upper layers caused by the pull of gravity on loose stones, gravel, and soft topsoil

Slow downhill movement, usually over relatively short distances, of near-surface masses of soil and loose rock material on hillslopes under the influence of gravity, soil dynamics (shrink– swell or freeze–thaw action), and soil-water movements. Same as surficial creep.
