In geomorphology, a terracette is a type of landform, a ridge on a hillside formed when saturated soil particles expand, then contract as they dry, causing them to move slowly downhill. An example of this is The Manger near the Uffington White Horse.
It may also be described as a small, irregular step-like formation on steep hillslopes, especially on those used for pasture which are formed by soil creep or erosion of surface soils exacerbated by the trampling of livestock such as sheep or cattle. Synonyms (not preferred) are: catstep, sheep or cattle track.
