Laguna Verde (Bolivia)
__NOTOC__ Laguna Verde (Spanish for "green lake") is a salt lake in an endorheic basin, in the southwestern Altiplano in Bolivia. It is located in the Sur Lípez Province of the Potosí Department. It is close to the Chilean border, at the foot of the volcano Licancabur. Geography The Laguna Verde is a lake at elevation. It covers an area of and has a depth of , and a narrow causeway divides it into two parts. It is at the southwestern extremity of the Eduardo Avaroa Andean Fauna National Reserve and Bolivia itself. It has mineral suspensions of arsenic and other minerals which renders colour to the lake waters. Its color varies from turquoise to dark emerald depending on the disturbance caused to sediments in the lake by winds. In the backdrop of the lake there is the inactive volcano Licancabur of in elevation, which is a nearly perfect cone. The shorelines west and east of the lake have different characteristics, with the western and southern shores eroded into volcanoes ...

Biome
A biome () is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate. Biomes may span more than one continent. Biome is a broader term than habitat and can comprise a variety of habitats. While a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A biota is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. Etymology The term was suggested in 1916 by Clements, originally as a synonym for '' biotic community'' of Möbius (1877). Later, it gained its c ...

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 t ...

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, 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 vents, parasitic centres known as the Ajata cones. These cones have generated lava flows. The volcano overlies a platform formed by lava domes and Andesite, 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 Chun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salar De Arizaro
Salar de Arizaro ("Arizaro" comes from Atacameno "crow", "condor" and , , "accommodation", "place where something is common".) is a large salt flat of the Andes in north-western Argentina. It is located between the villages of Tolar Grande and Caipe and near Mina La Casualidad, in Los Andes Department, Salta Province. Overview Located in the central-western area of the Puna de Atacama, it covers an area of 1,600 km2. Per extension, the Salar de Arizaro is the 6th largest salt flat in the World and the 2nd largest in Argentina after the Salinas Grandes. The salar area is mined for metallic and non-metallic resources, as it is rich in salt, marble, iron, copper and onyx. The nearest salt flats are the ones of Antofalla, Hombre Muerto (both in north of Catamarca Province), Pocitos (in the east) and the Salinas Grandes of Jujuy and Salta provinces. The Salar de Arizaro is crossed in the middle by the Salta–Antofagasta railway and by the Provincial Route 27 (par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salar De Atacama
Salar de Atacama is the largest salt flat in Chile. It is located south of San Pedro de Atacama, is surrounded by mountains, and has no drainage outlets. In the east it is enclosed by the main chain of the Andes, while to the west lies a secondary mountain range of the Andes called Cordillera de Domeyko. Large volcanoes dominate the landscape, including the Licancabur, Acamarachi, Aguas Calientes and the Láscar. The last is one of the most active volcanoes in Chile. All of them are located along the eastern side of the Salar de Atacama, forming a generally north-south trending line of volcanoes that separate it from smaller endorheic basins. Features The salt flat encompasses , is about long and wide, which makes it the third largest in the world, after Salar de Uyuni in Bolivia (). and Salinas Grandes in Argentina (). Its average elevation is about 2,300 m above sea level. The topography of the core portion of the ''salar'' exhibits a high level of roughness, the result of e ...

Salar De Uyuni
Salar de Uyuni (or "Salar de Tunupa") is the world's largest salt flat, or playa, at over in area. It is in the Daniel Campos Province in Potosí in southwest Bolivia, near the crest of the Andes at an elevation of above sea level. The Salar was formed as a result of transformations between several prehistoric lakes that existed around forty thousand years ago but had all evaporated over time. It is now covered by a few meters of salt crust, which has an extraordinary flatness with the average elevation variations within one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. The large area, clear skies, and exceptional flatness of the surface make the Salar ideal for calibrating the altimeters of Earth observation satellites. Following rain, a thin layer of dead calm water transforms the flat into the world's largest mirror, across. The Salar serves as the major transport route a ...

Salt Pan (geology)
Natural salt pans or salt flats are flat expanses of ground covered with salt and other minerals, usually shining white under the sun. They are found in deserts and are natural formations (unlike salt evaporation ponds, which are artificial). A salt pan forms by evaporation of a water pool, such as a lake or pond. This happens in climates where the rate of water evaporation exceeds the rate of that is, in a desert. If the water cannot drain into the ground, it remains on the surface until it evaporates, leaving behind minerals precipitated from the salt ions dissolved in the water. Over thousands of years, the minerals (usually salts) accumulate on the surface. These minerals reflect the sun's rays (through radiation) and often appear as white areas. Salt pans can be dangerous. The crust of salt can conceal a quagmire of mud that can engulf a truck. The Qattara Depression in the eastern Sahara Desert contains many such traps which served as strategic barriers during World ...

Altiplano
The Altiplano (Spanish for "high plain"), Collao (Quechua and Aymara: Qullaw, meaning "place of the Qulla") or Andean Plateau, in west-central South America, is the most extensive high plateau on Earth outside Tibet. The plateau is located at the latitude of the widest part of the north-south-trending Andes. The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, and its southwestern fringes lie in Chile. There are on the plateau several cities in each of these three nations, including El Alto, La Paz, Oruro, and Puno. The northeastern part of the Altiplano is more humid than the southwestern part, which has several salares (salt flats), due to its aridity. At the Bolivia–Peru border lies Lake Titicaca, the largest lake in South America. Farther south, in Bolivia, there was until recently a lake, Lake Poopó, but by December 2015 it had completely dried up, and was declared defunct. It is unclear whether that lake, which had been the second-largest in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
