Chungará Lake
Chungará is a lake situated in the extreme north of Chile at an elevation of , in the Altiplano of Arica y Parinacota Region in the Lauca National Park. It has a surface area of about and has a maximum depth of about . It receives inflow through the Río Chungara with some minor additional inflows, and loses most of its water to evaporation; seepage into the Laguna Quta Qutani plays a minor role. The lake formed between 8,000 and 17,000 years ago when the volcano Parinacota collapsed and the debris from the collapse dammed the Lauca River. Since then the lake has progressively grown owing to decreasing seepage. The lake is part of the Lauca National Park; a planned diversion of the lake's waters into the Azapa Valley being abandoned after a decision by the Chilean Supreme Court. Name The name ''Chungará'' or ''Chungara'' is derived from the Aymara language and has several different meanings: , a type of bush or moss plus the suffix that signifies "covered by"; but ...

Parinacota (volcano)
Parinacota (in Hispanicized spelling), Parina Quta or Parinaquta is a dormant volcano, dormant stratovolcano on the border of Bolivia and Chile. 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 volcanic landslide, landslide that spread west and formed a large, hummocky landslide deposit. The avalanche crossed and dammed a previously existing dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Titicaca
Lake Titicaca (; ; ) is a large freshwater lake in the Andes mountains on the border of Bolivia and Peru. It is often called the highest navigable lake in the world. Titicaca is the largest lake in South America, both in terms of the volume of water and surface area.Grove, M. J., P. A. Baker, S. L. Cross, C. A. Rigsby and G. O. Seltzer 2003 Application of Strontium Isotopes to Understanding the Hydrology and Paleohydrology of the Altiplano, Bolivia-Peru. ''Palaeogeography, Palaeoclimatology, Palaeoecology'' 194:281-297. It has a surface elevation of . Overview The lake is located at the northern end of the endorheic Altiplano basin high in the Andes on the border of Peru and Bolivia. The western part of the lake lies within the Puno Region of Peru, and the eastern side is located in the Bolivian La Paz Department (Bolivia), La Paz Department. The lake consists of two nearly separate subbasins connected by the Strait of Tiquina, which is across at the narrowest point. The lar ...

K'isi K'isini
K'isi K'isini (Aymara and Quechua expression, ''k'isi'' a stipa variety, the reduplication signifies there is a group or complex of something, the Aymara suffix ''-ni'' indicates ownership, "the one with a group of ''stipa''", Hispanicized spelling ''Quisi Quisini'') is a mountain in the Cordillera Occidental in the Andes of Bolivia. It is located in the Oruro Department, Sajama Province, Curahuara de Carangas Municipality, Sajama Canton.

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 Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fracture in the Crust (geology), crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also 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. Etymology The word ''lava'' comes from Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
