Cliff

In geography, a cliff is a significant vertical, or near vertical, rock exposure. Cliffs are categorized as erosion landforms due to the processes of erosion and weathering that produce them. Cliffs are common on coasts, in mountainous areas, escarpments, and along rivers. Generally speaking, cliffs are formed by rock that is resistant to erosion and weathering. Sedimentary rocks most likely to form cliffs are sandstone, limestone, chalk, and dolomite. Igneous rocks, such as Granite and basalt, also often form cliffs.

Most cliffs have some form of talus 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 often obscures the talus.

Many cliffs also feature waterfalls or rock shelters. Sometimes a cliff peters out at the end of a ridge, with tea tables or other types of rock columns remaining.

Some of the highest cliffs in the world are located in the United States at Yosemite National Park in California, where some are three thousand feet (almost one thousand meters) high, and at Kalaupapa, Hawaii, where the cliffs are over one thousand meters high.

Geography: Geography is the scientific study of the locational and spatial variation of both physical, biological and human phenomena on Earth. The word derives from the Greek words γη or γεια ("Earth") and γραφειν ("to describe" and "to wr...

Erosion: Erosion is the displacement of solids (soil, mud, rock, and so forth) by the agents of wind, water, ice, movement in response to gravity, or living organisms (in the case of bioerosion). Although the processes may be simultaneous, erosion is to be distinguished from weathering, which is the decompos...

Landform: A landform comprises a geomorphological unit. Landforms are categorised by characteristics such as elevation, slope, orientation, stratification, rock exposure, and soil type. Landforms by name include berms, mounds, hills, cliffs, valleys, and so forth. Oceans and continents exemplify highest-orde...
