Scree is a collection of broken rock fragments that accumulates at the base of a cliff or steep rocky slope through repeated rockfall. It forms mainly through freeze-thaw weathering, in which water entering cracks in the rock freezes and expands, gradually fracturing the rock face, with chemical weathering and lichen growth contributing further breakdown. The loose fragments move downslope and settle into a sloping apron, often sorted so that larger blocks collect nearer the base. The term is closely related to talus, though scree usually refers to the finer end of the same kind of rockfall debris.
