Inka Qhamachu
Inka Qhamachu (Quechua ''Inka'' Inca, ''qhamachu'' a species of wild tobacco ''(Nicotiana glauca)'', Hispanicized names ''Inca Camacho, Incacamachi'') is a mountain in the Andes of Bolivia. It is located in the Oruro Department, Litoral Province, Huachacalla Municipality. Inka Qhamachu lies southeast of Pacha Qullu, southeast of the village of Huachacalla (Wachaqalla). Inka Qhamachu is part of the Altiplano, an area of the Andes lying at altitudes of . The Altiplano has been affected by volcanic activity. Most of it including Inka Qhamachu is extinct, but in the Western Cordillera volcanic activity persists at Cerro Quemado, Guallatiri, Parinacota, Sajama and Tata Sabaya. Inka Qhamachu is a Pliocene age volcano, which rises from an altitude of . Its slopes range 11–16°, formed by lava flows and pyroclastic material. Erosion has carved radial gullies into its flanks, at whose ends alluvial fans have formed. Based on the degree of erosion, an age of 7.5 million years has be ...

Parinacota Volcano
Parinacota (in Hispanicized spelling), Parina Quta or Parinaquta is a dormant stratovolcano on the border of Chile and Bolivia. Together with Pomerape it forms the Nevados de Payachata volcanic chain. Part of the Central Volcanic Zone of the Andes, its summit reaches an elevation of above sea level. The symmetrical cone is capped by a summit crater with widths of or . Farther down on the southern slopes lie three parasitic centres known as the Ajata cones. These cones have generated lava flows. The volcano overlies a platform formed by lava domes and andesitic lava flows. The volcano started growing during the Pleistocene and formed a large cone. At some point between the Pleistocene and the Holocene, the western flank of the volcano collapsed, generating a giant landslide that spread west and formed a large, hummocky landslide deposit. The avalanche crossed and dammed a previously existing drainage, impounding or enlarging Lake Chungará; numerous other lakes now forming the ...

Tussock Grass
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any ha ...

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xerophytic
A xerophyte (from Greek ξηρός ''xeros'' 'dry' + φυτόν ''phuton'' 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water, such as a desert such as the Sahara or places in the Alps or the Arctic. Popular examples of xerophytes are cacti, pineapple and some Gymnosperm plants. The structural features ( morphology) and fundamental chemical processes (physiology) of xerophytes are variously adapted to conserve water, also common to store large quantities of water, during dry periods. Other species are able to survive long periods of extreme dryness or desiccation of their tissues, during which their metabolic activity may effectively shut down. Plants with such morphological and physiological adaptations are .” Xeromorphic”, The Cambridge Illustrated Glossary of Botanical Terms, Michael Hickey, Clive King, Cambridge University Press, 2001 Xerophytes such as cacti are capable of withstanding extended periods of dry cond ...

Oruro, Bolivia
Oruro (Hispanicized spelling) or Uru Uru is a city in Bolivia with a population of 264,683 (2012 calculation), about halfway between La Paz and Sucre in the Altiplano, approximately above sea level. It is Bolivia's fifth-largest city by population, after Santa Cruz de la Sierra, El Alto, La Paz, and Cochabamba. It is the capital of the Department of Oruro and the seat of the Roman Catholic Diocese of Oruro. Oruro has been subject to cycles of boom and bust owing to its dependence on the mining industry, notably tin, tungsten (wolfram), silver and copper. History The city was founded on November 1, 1606, by Don Manuel Castro de Padilla as a silver-mining center in the Urus region. At the time it was named Real Villa de San Felipe de Austria, after the Spanish monarch Philip III. It thrived for a while, but it was eventually abandoned as the silver mines became exhausted. Oruro was reestablished by European Bolivians in the late nineteenth century as a tin mining center. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyroclastic Rock
Pyroclastic rocks (derived from the el, πῦρ, links=no, meaning fire; and , meaning broken) are clastic rocks composed of rock fragments produced and ejected by explosive volcanic eruptions. The individual rock fragments are known as pyroclasts. Pyroclastic rocks are a type of volcaniclastic deposit, which are deposits made predominantly of volcanic particles. 'Phreatic' pyroclastic deposits are a variety of pyroclastic rock that forms from volcanic steam explosions and they are entirely made of accidental clasts. 'Phreatomagmatic' pyroclastic deposits are formed from explosive interaction of magma with groundwater. Unconsolidated accumulations of pyroclasts are described as tephra. Tephra may become lithified to a pyroclastic rock by cementation or chemical reactions as the result of the passage of hot gases ( fumarolic alteration) or groundwater (e.g. hydrothermal alteration and diagenesis) and burial, or, if it is emplaced at temperatures so hot that the soft glassy ...

Lava Flow
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tata Sabaya
Tata Sabaya is a high volcano in Bolivia. It is part of the Central Volcanic Zone, one of several volcanic belts in the Andes which are separated by gaps without volcanic activity. This section of the Andes was volcanically active since the Jurassic, with an episode of strong ignimbritic volcanism occurring during the Miocene. Tata Sabaya lies in a thinly populated region north of the Salar de Coipasa salt pan. Volcanic activity at Tata Sabaya and elsewhere in the Central Volcanic Zone is the consequence of the subduction of the Nazca Plate beneath the South America Plate. The volcano has developed along a lineament that separates older crust north of the lineament from younger crust in the south, and the edifice has been formed by andesitic rocks. The southern flank of Tata Sabaya failed during the latest Pleistocene about 12,000 - 12,360 years before present. Debris from the collapse entered a lake that covered the Salar de Coipasa at that time and formed a deposit with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevado Sajama
Nevado Sajama (; ) is an extinct stratovolcano and the highest peak in Bolivia. The mountain is located in Sajama Province, in Oruro Department. It is situated in Sajama National Park and is a composite volcano consisting of a stratovolcano on top of several lava domes. It is not clear when it erupted last but it may have been during the Pleistocene or Holocene. The mountain is covered by an ice cap, and ''Polylepis tarapacana'' trees occur up to elevation. Geography and geomorphology Nevado Sajama is located in the Sajama Province of the Oruro Department in Bolivia, about from the border with Chile. Cholcani volcano lies southeast of Sajama, and another neighbouring volcano, Pomerape, resembles Sajama in its appearance. A road runs along the southeastern flank of the volcano, with additional roads completing a circle around Sajama. The village of Sajma lies on its western foot, with the village of Caripe to the northeast of the mountain and Lagunas to the southwest, and th ...

Guallatiri
Guallatiri is a high volcano in Chile. It is located southwest of the Nevados de Quimsachata volcanic group and is sometimes considered to be part of that group. It is a stratovolcano with numerous fumaroles around the summit. The summit may be composed of either a lava dome or a pyroclastic cone, while the lower flanks of the volcano are covered by lava flows and lava domes. The volcano's eruptions have produced mostly dacite along with andesite and rhyolite. Guallatiri has been active in historical times with a number of eruptions, the latest in 1960 but a large prehistorical eruption took place 2,600 years ago. Fumarolic and seismic activity is ongoing and has resulted in the deposition of sulfur and other minerals on the volcano. The volcano is covered by an ice cap above elevation that has shrunk and fragmented during the course of the 20th-21st century. Guallatiri, along with several other volcanoes, is part of Lauca National Park and is monitored by SERNAGEOMIN. Name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
