Rift valley

A rift valley is a linear-shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault. A rift valley is formed on a divergent plate boundary, a crustal extension, a spreading apart of the surface, which is subsequently further deepened by the forces of erosion. When the tensional forces were strong enough to cause the plate to split apart, a center block dropped between the two blocks at its flanks, forming a graben. The drop of the center creates the nearly parallel steeply dipping walls of a rift valley when it is new. That feature is the beginning of the rift valley, but as the process continues, the valley widens, until it becomes a large basin that fills with sediment from the rift walls and the surrounding area. One of the best known examples of this process is the East African Rift. On Earth, rifts can occur at all elevations, from the sea floor to plateaus and mountain range in continental crust or in oceanic crust. They are often associated with a number of adjoining subsidiary or co-extensive valleys, which are typically considered part of the principal rift valley geologically.

Rift Valley

In order of specificity, Rift Valley can refer to:

Cusco

Cusco (/ˈkuːzkoʊ/), often spelled Cuzco (Spanish: Cuzco, [ˈkusko] or [ˈkuθko]; Quechua: Qusqu or Qosqo, IPA: [ˈqɔsqɔ]), is a city in southeastern Peru, near the Urubamba Valley of the Andes mountain range. It is the capital of the Cusco Region as well as the Cusco Province. In 2013, the city had a population of 435,114. Located on the eastern end of the Knot of Cuzco, its elevation is around 3,400 m (11,200 ft).

The site was the historic capital of the Inca Empire from the 13th into the 16th century until the Spanish conquest. In 1983 Cusco was declared a World Heritage Site by UNESCO. It has become a major tourist destination, receiving nearly 2 million visitors a year. The Constitution of Peru designates it as the Historical Capital of Peru.

Spelling and etymology

The indigenous name of this city is Qusqu. Although the name was used in Quechua, its origin has been found in the Aymara language. The word is derived from the phrase qusqu wanka ('Rock of the owl'), related to the city's foundational myth of the Ayar Siblings. According to this legend, Ayar Awqa (Ayar Auca) acquired wings and flew to the site of the future city; there he was transformed into a rock to mark the possession of the land by his ayllu ('lineage').

Cusco Region

Cusco (Quechua: Qosqo suyu, also spelled Cuzco) is a region in Peru. It is bordered by the Ucayali Region on the north; the Madre de Dios and Puno regions on the east; the Arequipa Region on the south; and the Apurímac, Ayacucho and Junín regions on the west. Its capital is Cusco, the capital of the Inca Empire.

Geography

The plain of Anta contains some of the best communal cultivated lands of the Cusco Region. It is located about 3,000 metres (9,800 ft) above sea level and is used to cultivate mainly high altitude crops such as potatoes, tarwi (edible lupin), barley and quinoa.

Languages

According to the 2007 Peru Census, the language learnt first by most of the residents was Quechua (51.40%) followed by Spanish (46.86%). The following table shows the results concerning the language learnt first in the Cusco Region by province:

Cusco (band)

Cusco was a German cross-cultural new-age music band named after the Peruvian city of Cusco, which was once the capital of the Inca Empire. The band's music contains influences from music around the world, with an emphasis on South American flute sounds and melodies. Cusco's melodic and energetic music is a fusion of modern and ethnic styles with influences from classical music and rock music sensibilities. Most of the ethnic instruments were keyboard-generated, giving the sound a synthetic quality.

The band was led by founders Michael Holm (Lothar Bernhard Walter; 1943–) and Kristian Schultze (1945–2011). Michael Holm, already a successful vocal artist, sought to make a musical tribute to ancient cultures. He and Kristian Schultze, formerly a member of the jazz band Passport, shared musical and historical interests. In 1979, they formed Cusco, and released their first album in 1980. They eventually signed with Higher Octave Music, releasing their first album on that label in 1988. Their albums consistently reached very high peaks on the instrumental/new age music sales charts. They were nominated for a Grammy award three times.
