The Andean region, located in central Colombia, is the most populated natural region of Colombia. With many mountains, the Andes contain most of the country's urban centers. [1] They were also the location of the most significant pre-Columbian indigenous settlements. Beyond the Colombian Massif in the south-western departments of Cauca and Nariño, the Colombian Andes divide into three branches known as "cordilleras" (from the Spanish for mountain range): the West Andes run adjacent to the Pacific coast and is home to the city of Cali. The Central Andes run up the center of the country between the Cauca and Magdalena river valleys (to the west and east respectively) and includes the cities of Medellín, Manizales and Pereira. The East Andes extend northeast towards the Guajira Peninsula, and includes the cities of Bogotá, Bucaramanga and Cúcuta.

The climate and vegetation of the region vary considerably according to altitude, but as a general rule the land can be divided into the tierra caliente (hot land) of river valleys and basins below 1,000 m; the more temperate conditions of the tierra templada (temperate land, approximately 1,000 m to 2,000 m) and tierra fría (cold land, 2,000 m to 3,200 m), which include the most productive land and most of the population; and the alpine conditions of the zona forestada (forested zone, 3,200 m to 3,900 m), páramos (3,900 m to 4,600 m) and tierra helada (frozen land, 4,600 m and above).

When the Spanish arrived, they divided Peru into three main regions: the coastal region, that is bounded by the Pacific Ocean; the highlands, that is located on the Andean Heights, and the jungle, that is located on the Amazonian Jungle. But Javier Pulgar Vidal, a geographer who studied the biogeographic reality of the Peruvian territory for a long time, proposed the creation of eight Natural Regions. In 1941, he presented his thesis "Las Ocho Regiones Naturales del Perú" at the III General Assembly of the Pan-American Institute of Geography and History.

<span class="mw-page-title-main">Colombian Massif</span>

The Colombian Massif, also known colloquially as Nudo de Almaguer, refers to a group of mountains within the Andes of south central Colombia. The massif is mainly within the area of the Cauca, Huila, and Nariño Departments. To the south is the Pasto Massif and to the north begins the Central and Eastern Andes.

The term Interandean valles refers to those valleys located in the Andes mountains.

<span class="mw-page-title-main">Natural regions of Colombia</span>

Because of its natural structure, Colombia can be divided into six distinct natural regions. These consist of the Andean Region, covering the three branches of the Andes mountains found in Colombia; the Caribbean Region, covering the area adjacent to the Caribbean Sea; the Pacific Region adjacent to the Pacific Ocean; the Orinoquía Region, part of the Llanos plains mainly in the Orinoco river basin along the border with Venezuela; the Amazon Region, part of the Amazon rainforest; and finally the Insular Region, comprising the islands in both the Atlantic and Pacific Oceans. Colombia is located in South America.

<span class="mw-page-title-main">Climate of Colombia</span> Tropical and isothermal

The Climate of Colombia is characterized for being tropical and isothermal as a result of its geographical location near the Equator presenting variations within five natural regions and depending on the altitude, temperature, humidity, winds and rainfall. Each region maintains an average temperature throughout the year only presenting variables determined by precipitation during a rainy season caused by the Intertropical Convergence Zone.

<span class="mw-page-title-main">Patía Valley dry forests</span>

The Patía Valley dry forests (NT0225) is an ecoregion in southwestern Colombia. It covers a dry valley surrounded by mountains. The original habitat has mostly been destroyed by human activity, although a few pockets remain.

<span class="mw-page-title-main">Táchira Depression</span>

The Táchira Depression is a saddle of land connecting the Lake Maracaibo basin to the Orinoco basin in the state of Táchira, Venezuela. It forms a break in the eastern Andes, separating the Tamá Massif to the west from the Cordillera de Mérida to the east. The depression has been thought to present a barrier to the movement of species between the Colombian and Venezuelan Andes, but this effect may have been relatively low during the recent ice ages. The mountains of the region have potential for coffee farming and hydroelectric power generation, while the lower levels are suitable for farming.

<span class="mw-page-title-main">Chocó–Darién moist forests</span>

The Chocó–Darién moist forests (NT0115) is an ecoregion in the west of Colombia and east of Panama. The region has extremely high rainfall, and the forests hold great biodiversity. The northern and southern parts of the ecoregion have been considerably modified for ranching and farming, and there are threats from logging for paper pulp, uncontrolled gold mining, coca growing and industrialisation, but the central part of the ecoregion is relatively intact.

<span class="mw-page-title-main">Cauca Valley montane forests</span>

The Cauca Valley montane forests (NT0109) is an ecoregion in western Colombia. It covers the sides of the Cauca Valley, which runs from south to north between the Central and Western Ranges (cordilleras) of the Colombian Andes. The ecoregion is home to very diverse fauna and flora, due in part to its varied elevations and climates, in part to its position near the isthmus of Panama, the route along which North American species invaded South America and then diversified as they moved to the upper parts of the Andes. Little of the original habitat remains at lower levels, but higher up there are sizeable blocks of forest, some of which are protected.

The Romeral Fault System is a megaregional system of major parallel and anastomosing faults in the Central Ranges of the Colombian Andes and the Cauca, Amagá, and Sinú-San Jacinto Basins. The system spans across ten departments of Colombia, from northeast to south Bolívar, Sucre, Córdoba, Antioquia, Caldas, Risaralda, Quindío, Valle del Cauca, Cauca and Nariño. The fault zone extends into Ecuador where it is known as the Peltetec Fault System. The in detail described part of the Romeral Fault System south of Córdoba has a total length of 697.4 kilometres (433.3 mi) with a cumulative length of 1,787.9 kilometres (1,110.9 mi) and runs along an average north to south strike of 017.6 ± 16, cross-cutting the central-western portion of Colombia.
