Pico Humboldt
Pico Humboldt is Venezuela's second highest peak, at 4,925 metres above sea level. It is located in the Sierra Nevada de Merida, in the Venezuelan Andes of ( Mérida State). The peak, its sister peak Pico Bonpland, and the surrounding páramos are protected by the Sierra Nevada National Park. The mountain is named after German explorer and naturalist Alexander von Humboldt. Glaciers The summit was formerly surrounded by glaciers, including the two largest out of the four glaciers remaining in the country (the other two smaller glaciers were on Pico Bolívar). The glaciers on Humboldt Peak (as most tropical glaciers) have been receding fast since the 1970s. By 2009, all but one glacier, the Humboldt Glacier, had vanished. In 2019, the remaining glacier covers an area of 0.1 km2 and was forecast to melt completely within a decade: in May 2024, the Humboldt Glacier was officially downgraded to an ice field, no longer considered a glacier.

Mérida, Mérida
Mérida, officially known as ''Santiago de los Caballeros de Mérida'', is the capital of the municipality of Libertador and the state of Mérida, and is one of the main cities of the Venezuelan Andes. It was founded in 1558 by Captain Juan Rodríguez Suárez, forming part of Nueva Granada, but later became part of the Captaincy General of Venezuela and played an active role in the War of Independence. The capital city's population is 204,879 inhabitants, and the metropolitan area, that includes the municipality of Libertador, reaches 345,489 people (Census 2001). The city accounts for 28% of the total population of Mérida State, which has more than 750,000 inhabitants (Census 2001). It is home to the University of Los Andes and the Archdiocese of Mérida. It also has the highest and longest cable car in the world. It is the largest student and tourist center of western Venezuela. The mass transit system ( Trolebús Mérida) is available as a means of tourist transport. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropics
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

Geography Of Mérida (state)
Geography (from Ancient Greek ; combining 'Earth' and 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaciers Of Venezuela
A glacier ( ) or () is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation (phase transition), sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. Because glacial mass is affected by long-term climate changes, e.g., precipitation (meteorology), precipitation, temperature, mean temperature, and cloud cover, Retreat of glaciers since 1850, glacial mass changes are considered among the most sensitive indicators of climate change. There are about 198,000 to 200,000 glaciers in the world.

Mountains Of Venezuela
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...

IUCN Red List Of Ecosystems
The IUCN Red List of Ecosystems (RLE) is a global framework for monitoring and documenting the status of ecosystems. It was developed by the International Union for Conservation of Nature for biodiversity risk assessment. Its main objectives are to support conservation, resource use, and management decisions by evaluating all the world's ecosystems by 2025. The Red List of Ecosystem was developed by the International Union for Conservation of Nature (IUCN), the same entity that created the Red List of Threatened Species, a global framework to monitor the level of risk of animal and plant species. With the help of RLE and its partner organizations, many governments and organizations create national and regional red lists, generally based on the IUCN categories and criteria, to classify the ecosystems under threat within their territorial limits. History The Red List of Ecosystems was created to carry out assessments of biodiversity at a level of biological organization above ...

Glacier Forefield
The region between the current leading edge of the glacier and the moraines of latest maximum is called glacier foreland or glacier forefield. In the Alps this maximum was in 1850 and since then the region has become ice free due to deglaciation. Because of this relative recent development of vegetation and morphodynamic the glacier foreland differs considerably from the surrounding landscape.

Proglacial Lakes
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Geographic
''National Geographic'' (formerly ''The National Geographic Magazine'', sometimes branded as ''Nat Geo'') is an American monthly magazine published by National Geographic Partners. The magazine was founded in 1888 as a scholarly journal, nine months after the establishment of the society, but is now a popular magazine. In 1905, it began including pictures, a style for which it became well known. Its first color photos appeared in the 1910s. During the Cold War, the magazine committed itself to present a balanced view of the physical and human geography of countries beyond the Iron Curtain. Later, the magazine became outspoken on environmental issues. Until 2015, the magazine was completely owned and managed by the National Geographic Society. Since 2015, controlling interest has been held by National Geographic Partners. Topics of features generally concern geography, history, nature, science, and world culture.

Retreat Of Glaciers Since 1850
The retreat of glaciers since 1850 is a well-documented effects of climate change, effect of climate change. The retreat of Mountain glacier, mountain glaciers provides evidence for the Instrumental temperature record, rise in global temperatures since the late 19th century. Examples include mountain glaciers in western North America, Asia, Alps, the Alps in central Europe, and tropical and subtropical regions of South America and Africa. Since glacial mass is affected by long-term climatic changes, e.g. Precipitation (meteorology), precipitation, Temperature, mean temperature, and cloud cover, glacial mass changes are one of the most sensitive indicators of climate change. The retreat of glaciers is also a major reason for sea level rise. Excluding peripheral glaciers of Ice sheet, ice sheets, the total cumulated global glacial losses over the 26 years from 1993 to 2018 were likely 5500 gigatons, or 210 gigatons per year.Fox-Kemper, B., H.T.

Pico Bolívar
Pico Bolívar is the highest mountain in Venezuela, at 4,978 metres (16,332 ft). Located in Mérida State. It can be reached only by walking; the Mérida cable car, which was the highest and longest cable car in the world when it was built, only reaches Pico Espejo. From there it is possible to climb to Pico Bolívar. The peak is named after the Venezuelan independence hero Simón Bolívar. The Pico Bolívar is located on the mountain previously called La Columna, next to El León (4,743 m) and El Toro (4,695 m). The new name was suggested by Tulio Febres Cordero in 1925. It was officially renamed on December 30, 1934. Elevation The height of this prominent Andean peak has been estimated and calculated various times during history. In 1912, one triangular measurement pointed at . In 1928 came another calculation at , which stood as official height for a long time. During the 1990s, the scientists Heinz Saler and Carlos Abad calculated the height, based upon GPS observa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
