In geography and geology, a cliff is a vertical, or nearly vertical, rock exposure. Cliff_sentence_5

Cliffs are formed as erosion landforms by the processes of weathering and erosion. Cliff_sentence_6

Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliff_sentence_7

Cliffs are usually formed by rock that is resistant to weathering and erosion. Cliff_sentence_8

Sedimentary rocks most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Cliff_sentence_9

Igneous rocks such as granite and basalt also often form cliffs. Cliff_sentence_10

An escarpment (or scarp) is a type of cliff, formed by the movement of a geologic fault or landslide, or by differential erosion of rock layers of differing hardness. Cliff_sentence_11

Most cliffs have some form of scree slope at their base. Cliff_sentence_12

In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. Cliff_sentence_13

In areas of higher moisture, a soil slope may obscure the talus. Cliff_sentence_14

Many cliffs also feature tributary waterfalls or rock shelters. Cliff_sentence_15

Sometimes a cliff peters out at the end of a ridge, with mushroom rocks or other types of rock columns remaining. Cliff_sentence_16

Coastal erosion may lead to the formation of sea cliffs along a receding coastline. Cliff_sentence_17

The Ordnance Survey distinguishes between cliffs (continuous line along the top edge with projections down the face) and outcrops (continuous lines along lower edge). Cliff_sentence_18

Etymology Cliff_section_0

Cliff comes from the Old English word clif of essentially the same meaning, cognate with Dutch, Low German, and Old Norse klif 'cliff'. Cliff_sentence_19

These may in turn all be from a Romance loanword into Primitive Germanic that has its origins in the Latin forms clivus / clevus ("slope" or "hillside"). Cliff_sentence_20

Several big granite faces in the Arctic region vie for the title of 'highest vertical drop on Earth', but reliable measurements are not always available. Cliff_sentence_26

The possible contenders include (measurements are approximate): Cliff_sentence_27

Mount Thor, Baffin Island, Canada; 1,370 m (4,500 ft) total; top 480 m (1600 ft) is overhanging. Cliff_sentence_28

This is commonly regarded as being the largest vertical drop on Earth ot:leapyear at 1,250 m (4,100 ft). Cliff_sentence_29

  • Innumerable peaks in the Drakensberg mountains of South Africa are considered cliff formations. The Drakensberg Range is regarded, together with Ethiopia's Simien Mountains, as one of the two finest erosional mountain ranges on Earth. Because of their near-unique geological formation, the range has an extraordinarily high percentage of cliff faces making up its length, particularly along the highest portion of the range. This portion of the range is virtually uninterrupted cliff faces, ranging from 600 m (2,000 ft) to 1,200 m (3,900 ft) in height for almost 250 km (160 mi). Of all, the "Drakensberg Amphitheatre" (mentioned above) is most well known. Other notable cliffs include the Trojan Wall, Cleft Peak, Injisuthi Triplets, Cathedral Peak, Monk's Cowl, Mnweni Buttress, etc. The cliff faces of the Blyde River Canyon, technically still part of the Drakensberg, may be over 800 m (2,600 ft), with the main face of the Swadini Buttress approximately 1,000 m (3,300 ft) tall.Cliff_item_9_108

As habitat determinants Cliff_section_9

Cliff landforms provide unique habitat niches to a variety of plants and animals, whose preferences and needs are suited by the vertical geometry of this landform type. Cliff_sentence_36

For example, a number of birds have decided affinities for choosing cliff locations for nesting, often driven by the defensibility of these locations as well as absence of certain predators. Cliff_sentence_37
