Etymology[ edit ] The name of the mountains is a translation of an Amerindian name that is closely related to Algonquian ; the Cree name as-sin-wati is given as, "When seen from across the prairies, they looked like a rocky mass". The first mention of their present name by a European was in the journal of Jacques Legardeur de Saint-Pierre inwhere they were called "Montagnes de Roche".
The high Andes have an impoverished animal life. Species there have had to adapt to the harsh and cold environment, scanty vegetation, and low oxygen pressure.
The great number of lakes in the region has attracted many aquatic birds, including flamingos, which nest up… Physical features There is no universal agreement about the major north-south subdivisions of the Andes system.
For the purposes of this discussion, the system is divided into three broad categories. From south to north these are the Southern Andesconsisting of the Chilean, Fuegian, and Patagonian cordilleras; the Central Andes, including the Peruvian cordilleras; and the Northern Andesencompassing the Ecuadorian, Colombian, and Venezuelan or Caribbean cordilleras.
Geology The Andean mountain system is the result of global plate-tectonic forces during the Cenozoic Era roughly the past 65 million years that built upon earlier geologic activity. The subsequent breakup of Pangaea and of its southern portion, Gondwanadispersed these plates outward, where they began to take the form and position of the present-day continents.
The collision or convergence of two of these plates—the continental South American Plate and the oceanic Nazca To what extent are cold mountain —gave rise to the orogenic mountain-building activity that produced the Andes.
Many of the rocks comprising the present-day cordilleras are of great age. The weight of these deposits forced a subsidence downwarping of the crust, and the resulting pressure and heat metamorphosed the deposits into more resistant rocks; thus, sandstone, siltstone, and limestone were transformed, respectively, into quartzite, shale, and marble.
Approximately million years ago this complex geologic matrix began to be uplifted as the eastern edge of the Nazca Plate was forced under the western edge of the South American Plate i. This subduction-uplift process was accompanied by the intrusion of considerable quantities of magma from the mantle, first in the form of a volcanic arc along the western edge of the South American Plate and later by the injection of hot solutions into surrounding continental rocks; the latter process created numerous dikes and veins containing concentrations of economically valuable minerals that later were to play a critical role in the human occupation of the Andes.
The intensity of this activity increased during the Cenozoic Era, and the present shape of the cordilleras emerged.
The accepted time period for their rise had been from about 15 million to 6 million years ago. However, through the use of more advanced techniques, researchers in the early 21st century were able to determine that the uplift started much earlier, about 25 million years ago.
The resultant mountain system exhibits an extraordinary vertical differential of more than 40, feet between the bottom of the Peru-Chile Atacama Trench off the Pacific coast of the continent and the peaks of the high mountains within a horizontal distance of less than miles.
The tectonic processes that created the Andes have continued to the present day. The system—part of the larger circum-Pacific volcanic chain that often is called the Ring of Fire—remains volcanically active and is subject to devastating earthquakes.
Physiography of the Southern Andes The Fuegian Andes begin on the mountainous Estados Staten Island, the easternmost point of the Tierra del Fuego archipelago, reaching an elevation of 3, feet. They run to the west through Grande Island, where the highest ridges—including Mounts DarwinValdivieso, and Sorondo—are all less than 7, feet high.
The physiography of this southernmost subdivision of the Andes system is complicated by the presence of the independent Sierra de la Costa. The Patagonian Andes rise north of the Strait of Magellan.
Numerous transverse and longitudinal depressions and breaches cut this wild and rugged portion of the Andes, sometimes completely; many ranges are occupied by ice fields, glaciers, rivers, lakes, or fjords. The line of permanent snow becomes higher in elevation with decreasing latitude in the Southern Andes: Those depressions that are free of water form fertile valleys called vegas, which are easily reached by low passes.
Magnificent and impenetrable forests grow on both sides of these cordilleras, especially on the western slopes; these forests cover the mountains as high as the snow linealthough at the higher altitudes toward the north and in Tierra del Fuego the vegetation is lower and less dense. Its width increases to about 50 miles, and it becomes arid and higher; the passes, too, are higher and more difficult to cross.
Glaciers are rare and found only at high elevations. The main range serves as the boundary between Chile and Argentina and also is the drainage divide between rivers flowing to the Pacific and the Atlantic. The last of the southern series of volcanoes, Mount Tupungato 21, feet is just east of Santiago, Chile.
A line of lofty, snowcapped peaks rise between Tupungato and the mighty Mount Aconcagua. To the north of Aconcagua lies Mount Mercedario 22, feetand between them are the high passes of Mount Espinacito 16, feet and Mount Patos 12, feet.
South of Anconcagua the passes include Pircas 16, feetBermejo more than 10, feetand Iglesia 13, feet. Farther north the passes are more numerous but higher. To the north is found a transverse depression and the southern limit of the high plateau region called the Atacama Plateau in Argentina and Chile and the Altiplano in Bolivia and Peru.
The cordillera grows wider as it advances into Bolivia and Peru, where the great plateau is bounded by two ranges: The two main ranges and several volcanic secondary chains enclose depressions called salars because of the deposits of salts they contain; in northwestern Argentina, the Sierra de Calalaste encompasses the large Antofalla Salt Flat.
The western slopes of the Cordillera Occidental descend gradually to the Atacama Desert along the coast. The Cordillera Oriental to the east, lower and built on a broad bed of lava, is cut and denuded by rivers with steep gradients, fed by heavy rainfall. It has two sections.
The southern portion is miles wide and—with the exception of Chorolque Peak in Bolivia 18, feet —of relatively low elevation.The Rocky Mountains, also known as the Rockies, are a major mountain range in western North America.
The Rocky Mountains stretch more than 4, kilometres (3, mi) from the northernmost part of British Columbia, in western Canada, to New Mexico, in the Southwestern United States.

Both stories establish a torrid romantic magnetism between two big stars, and then keep them far apart for almost the entire movie. Filling the gap in both films is a quirky supporting character who makes us unreasonably grateful, because the leads take themselves very seriously 3/5.
