Qori Kalis Glacier
The Qori Kalis Glacier is a tropical glacier located in the Cordillera Oriental section of the Andes mountains of Peru. It is one of the few tropical glaciers left in the world, and is the main outlet of the Quelccaya Ice Cap. This glacier has lost nearly half of its length since measurements began in 1963 by the Peruvian hydro-electric company Electroperú. Around 2007, the glacier had been retreating at a rate of 600 feet per year. From 1963 to 1978 it retreated at a rate of approximately 6 metres per year. Between 1991 and 2005, it has retreated at around 60 metres per year. It is the largest of all of the tongues of the Quelccaya Ice Cap, many of which are in retreat. Testing shows that the Qori Kalis Glacier advanced to its greatest length around 520 years ago and then began to retreat. It has advanced to small degrees from time to time since then.

Quelccaya Ice Cap
The Quelccaya Ice Cap (also known as Quenamari Ice Cap) is the second largest glaciated area in the tropics, after Coropuna. Located in the Cordillera Oriental section of the Andes mountains in Peru, the cap covers an area of with ice up to thick. It is surrounded by tall ice cliffs and a number of outlet glaciers, the largest of which is known as Qori Kalis Glacier; lakes, moraines, peat bogs and wetlands are also present. There is a rich flora and fauna, including birds that nest on the ice cap. Quelccaya is an important source of water, eventually melting and flowing into the Inambari and Vilcanota Rivers. A number of ice cores have been obtained from Quelccaya, including two from 1983 that were the first recovered outside of the polar regions. Past climate states have been reconstructed from data in these ice cores; these include evidence of the Little Ice Age, regional droughts and wet periods with historical significance and past and recent El Niño events.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Cordillera Oriental (Peru)
The Cordillera Oriental (Spanish for eastern mountain range) is the eastern part of the Andes in Peru. This range contains Paleozoic metamorphic rocks. It includes many subsidiary ranges such as the Vilcanota, Vilcabamba, Urubamba and Carabaya mountain ranges and peaks above 6,000 m such as Salcantay. The highest peak is Nevado Ausangate at 6372 m. See also * Cordillera Central (Peru) The Cordillera Central (Spanish for central mountain range) is part of the Andes in Peru. It extends in a northerly direction approximately between 11º 39’ and 12º 37’S and 75º 30’ and 76º 20’W (or between 11°37' and 12°26'S and 75 ...

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, MedellÃn, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...

Electricity Sector In Peru
The electricity sector in Peru has experienced large improvements in the past 15 years. Access to electricity has increased from 45% in 1990 to 96.4% in 2018, while service quality and efficiency of service provision improved. These improvements were made possible through privatizations following reforms initiated in 1992. At the same time, electricity tariffs have remained in line with the average for Latin America. However, several challenges remain. Chief among them are the still very low level of access in rural areas and the untapped potential of some renewable energies, in particular wind and solar energy, due to an inadequate regulatory framework. The current electricity generation capacity is evenly divided between thermal and hydroelectric sources. A renewed recent dynamism of the electricity sector in the country is based on the shift to natural gas plants, which will be mainly fed from the production of the Camisea gas field in the Amazon Rainforest.

Proglacial Lake
In geology, a proglacial lake is a lake formed either by the damming action of a moraine during the retreat of a melting glacier, a glacial ice dam, or by meltwater trapped against an ice sheet due to isostatic depression of the crust around the ice. At the end of the last ice age about 10,000 years ago, large proglacial lakes were a widespread feature in the northern hemisphere. Moraine-dammed The receding glaciers of the tropical Andes have formed a number of proglacial lakes, especially in the Cordillera Blanca of Peru, where 70% of all tropical glaciers are. Several such lakes have formed rapidly during the 20th century. These lakes may burst, creating a hazard for zones below. Many natural dams (usually moraines) containing the lake water have been reinforced with safety dams. Some 34 such dams have been built in the Cordillera Blanca to contain proglacial lakes. Several proglacial lakes have also formed in recent decades at the end of glaciers on the eastern side of Ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
