Cliffs are categorized as Erosion Landform s due to the processes of erosion and Weathering that produce them. Cliffs are common on Coast s, in Mountain ous areas, Escarpment s and along River s. Cliffs are usually formed by Rock that is resistant to Erosion and Weathering . Sedimentary Rock s most likely to form cliffs are Sandstone , Limestone , Chalk , and Dolomite . Igneous Rock s, such as Granite and Basalt also often form cliffs. An Escarpment (or scarp) is a type of cliff, formed by the movement of a Geologic Fault , or a Landslide . Most cliffs have some form of Scree slope at their base. In arid areas or under high cliffs, these are generally exposed jumbles of fallen rock. In areas of higher moisture, a Soil slope may obscure the talus. Many cliffs also feature Tributary Waterfall s or Rock Shelter s. Sometimes a cliff peters out at the end of a ridge, with Tea Table s or other types of rock columns remaining. Given that a cliff need not be exactly vertical, there can be ambiguity about whether a given slope is a cliff or not, and also about how much of a certain slope to count as a cliff. (For example, given a truly vertical rock wall above a very steep slope, one could count only the rock wall, or the combination.) This makes listings of cliffs an inherently uncertain endeavor. |
