Principal Cordillera
Principal Cordillera () is the Andean mountain range that makes up the boundary between Central Chile and neighbouring areas of Argentina. It is also a continental divide between the Atlantic and the Pacific watersheds. It extends in a north–south direction in the Argentine provinces of La Rioja, San Juan and Mendoza and the Chilean regions of Valparaíso, Santiago, O'Higgins and Maule. To the east of the Principal Cordillera lies the Frontal Cordillera which is fully in Argentina. Aconcagua, the tallest mountain outside Asia, lies in the Principal Cordillera. Geological history What is today the Principal Cordillera was once a depression that accumulated sediments.Charrier ''et al''. 2006, pp. 93–94. Lava flows from ancient volcanoes also found their way to the depression. Today these sequences of sedimentary and volcanic rock can be observed high in the Andes, implying their basin was closed and uplifted by tectonic inversion. The said rocks are grouped in the Abanic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevado El Plomo, Cerro Juncal To The South
Nevado (1813? – 1821) was a Mucuchies dog that was given to Simón Bolívar by the local people of Mucuchíes, Mérida (state), Mérida, in the Venezuelan Andes. Life It was given as a kind of present shortly after the Battle of Niquitao during his triumphal Admirable Campaign from United Provinces of New Granada, New Granada (today Colombia) to Caracas in 1813. Bolivar's army was approaching a farm when the independence fighters were stopped in their tracks by a giant, barking guard dog. Weapons drawn, the rebels were about to kill the dog when Bolivar, marveling at its beauty and bravery, ordered them to back down. Nevado always ran beside Bolívar's horse, no matter if he traveled through cities or battlefields. Nevado died in the Battle of Carabobo on June 24, 1821. When Bolívar received news that Nevado was badly injured, he rushed to the dog, but he came too late. Several monuments to Nevado stand at the entrance of Mucuchíes town.

Argentina–Chile Border
The Argentina–Chile border is the longest international border of South America and the third longest in the world after the Canada–United States border and the Kazakhstan–Russia border. With a length of , it separates Argentina from Chile along the Andes and on the islands of Tierra del Fuego. However, there are some Argentina–Chile relations#Border issues, border disputes, particularly around the Southern Patagonian Ice Field. It is the largest border of the two countries, beating the Argentina–Paraguay border, Argentina–Paraguay and Bolivia–Chile border, Chile–Bolivia, Argentina's and Chile's second largest borders, respectively. Description The northern end of the border is a tripoint it forms with those at the Argentina–Bolivia border and the Bolivia-Chile border in the arid Puna de Atacama plateau. The border extends south until reaching the sea at the same place the Strait of Magellan meets the Atlantic Ocean. Further south the border on the Isla Grande ...

Geography Of Santiago Metropolitan Region
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] |
Mountain Ranges Of Chile
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 ...

Valley Glacier
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small cirque glaciers found perched on mountain tops. Glaciers can be grouped into two main categories: * Ice flow is constrained by the underlying bedrock topography * Ice flow is unrestricted by surrounding topography Unconstrained Glaciers Ice sheets and ice caps Ice sheets and ice caps cover the largest areas of land in comparison to other glaciers, and their ice is unconstrained by the underlying topography. They are the largest glacial ice formations and hold the vast majority of the world's fresh water. Ice sheets Ice sheets are the largest form of glacial formation. They are continent-sized ice masses that span areas over . They are dome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
