Scree is a type of rock debris consisting of broken fragments of rocks, typically found at the base of a mountain or cliff. TALUS is another term for scree, which is derived from the French word for 'SLOPE'. It is composed of angular fragments of rocks that have been broken off by natural processes such as frost wedging and erosion. Scree is an important part of the natural environment, providing habitats for plants and animals, and helping to prevent soil erosion.
