The Grand Canyon, Arizona, at the confluence of the Colorado River and Little Colorado River.. A canyon (from Spanish: cañón; archaic British English spelling: cañon), [1] gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. [2]

The Capertee Valley (pronounced Kay-per-tee) is a large canyon in New South Wales, Australia, 135 km (84 mi) north-west of Sydney that is noted to be the second widest of any canyon in the world, exceeding the Grand Canyon.
Some sections of a stream or river valleys may have vertically incised their course to such an extent that the valley they occupy is best described as a gorge, ravine, or canyon. Rapid down-cutting may result from localized uplift of the land surface or rejuvenation of the watercourse as a result for example of a reduction in the base level to ...
A ravine is a landform that is narrower than a canyon and is often the product of streambank erosion. Ravines are typically classified as larger in scale than gullies, although smaller than valleys. [1] Ravines may also be called a cleuch, dell, ghout , gill or ghyll, glen, gorge, kloof (South Africa), and chine (Isle of Wight)
The canyon has a length of about 240 kilometres (150 mi) as the gorge bends around Mount Namcha Barwa (7,782 metres or 25,531 feet) and cuts its way through the eastern Himalayas. Its waters drop from about 2,900 metres (9,500 ft) near Pei to about 1,500 metres (4,900 ft) at the end of the Upper Gorge where the Po Tsangpo River enters.
the Canyon from l’Imbut to the Pont du Galetas. The Verdon Gorge is narrow and deep, with depths of 250 to 700 metres and widths of 6 to 100 metres at the level of the Verdon river. It is 200 to 1500 metres wide from one side of the Gorge to the other at the summits. The Gorge has been compared to the Grand Canyon in the United States. [4]
