Peruvian Western Cordillera
In Peru the Cordillera Occidental is the western branch of the Andes. It bounds to the west with coastal plains or falls directly into the Pacific along cliffed coasts. To the east of Cordillera Occidental lies the Cordillera Central and the Cordillera Oriental of Peru. As with other parts of the Peruvian Andes the Cordillera Occedental bears evidence on the Andean orogeny The Andean orogeny () is an ongoing process of orogeny that began in the Early Jurassic and is responsible for the rise of the Andes mountains. The orogeny is driven by a reactivation of a long-lived subduction system along the western margin o .... References Mountain ranges of Peru Mountain ranges of the Andes {{Peru-geo-stub ...

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

Peru
Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the south and west by the Pacific Ocean. Peru is a Megadiverse countries, megadiverse country, with habitats ranging from the arid plains of the Pacific coastal region in the west, to the peaks of the Andes mountains extending from the north to the southeast of the country, to the tropical Amazon basin rainforest in the east with the Amazon River. Peru has Demographics of Peru, a population of over 32 million, and its capital and largest city is Lima. At , Peru is the List of countries and dependencies by area, 19th largest country in the world, and the List of South American countries by area, third largest in South America.

Cliffed Coast
A cliffed coast, also called an abrasion coast, is a form of coast where the action of marine waves has formed steep cliffs that may or may not be precipitous. It contrasts with a Flat coast, flat or alluvial coast. Formation In coastal areas in which the land surface dips at a relatively steep angle below the water table, the continuous action of marine waves on the coastline, known as Abrasion (geology), abrasion, may create a steep declivity known as a cliff, the slope angle of which depends on a variety of factors including the jointing, bedding and hardness of the materials making up the cliff as well as the erosional processes themselves.Herbert Louis and Klaus Fischer: ''Allgemeine Geomorphologie'', de Gruyter, 4th ed., Berlin 1979, pp. 532-537 The slope is constantly being eroded. The waves attacking the cliff-foot form a wave-cut notch by constant abrasion action producing an overhang. This overhang grows in size as the cliff is undercut, until it collapses und ...

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°30' and 76°18'W) for about 60 km to 100 km. It contains the Paryaqaqa (P), Yauyos (Y) and Pichqa Waqra (PW) mountain ranges. It is located in the Junín Region and in the Lima Region The Department of Lima (), known as the Department of the Capital () until 1823, is a department and region located in the central coast of Peru; the seat of the regional government is Huacho. Lima Province, which contains the city of Lima, .... The name ''Cordillera Central'' is also applied for one of the three ranges that cross Peru in a northwesterly direction between the Cordillera Occidental ("the western range") where the Cordillera Central of the Junín and Lima Regions is located and the Cordillera Oriental ("the eastern range" ...

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 Cordillera Vilcanota, Vilcanota, Vilcabamba mountain range, Vilcabamba, Urubamba mountain range, Urubamba and Carabaya mountain range, Carabaya mountain ranges and peaks above 6,000 m such as Salcantay. The highest peak is Nevado Ausangate at 6372 m.

Andean Orogeny
The Andean orogeny () is an ongoing process of orogeny that began in the Early Jurassic and is responsible for the rise of the Andes mountains. The orogeny is driven by a reactivation of a long-lived subduction system along the western margin of South America. On a continental scale the Cretaceous (90 Ma) and Oligocene (30 Ma) were periods of re-arrangements in the orogeny. The details of the orogeny vary depending on the segment and the geological period considered. Overview Subduction orogeny has been occurring in what is now western South America since the break-up of the supercontinent Rodinia in the Neoproterozoic. The Paleozoic Pampean, Famatinian and Gondwanan orogenies are the immediate precursors to the later Andean orogeny.Charrier ''et al''. 2006, pp. 113–114. The first phases of Andean orogeny in the Jurassic and Early Cretaceous were characterized by extensional tectonics, rifting, the development of back-arc basins and the emplacement of large batholiths.

Mountain Ranges Of Peru
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, mountai ...
