Title: Outline of Bolivia
Content:   The following outline is provided as an overview of and topical guide to Bolivia: Bolivia &ndash; landlocked sovereign country located in central South America. Bolivia is bordered on the north and the east by Brazil, on the southeast by Paraguay, on the south by Argentina, and on the west by Chile and Peru. Its geography varies from the peaks of the Andes mountains to the tropical forests of the Amazon Basin. It is a developing country, and its main economic activities include agriculture, mining, and manufacturing of products such as textiles.
Title: Argentina–Bolivia border
Content:  The Argentina–Bolivia border is the international boundary between Argentina and Bolivia. From west to east, the border goes from the Altiplano to extend to the Chaco flat through the tropical environment of the Yungas.
Title: Geography of Bolivia
Content:  The geography of Bolivia includes the Eastern Andes Mountain Range (also called the Cordillera Oriental) which bisects Bolivia roughly from north to south. To the east of that mountain chain are lowland plains of the Amazon Basin, and to the west is the Altiplano which is a highland plateau where Lake Titicaca is located. Bolivia's geography has features similar to those of Peru which abuts Bolivia's northwest border; like Bolivia, Peru is bisected from north to south by the Eastern Andes Mountains, and these two countries share Lake Titicaca which is the highest navigable lake on Earth. Unlike Peru, however, Bolivia is one of the two landlocked countries in South America, the other being Paraguay which is located along Bolivia's southeast border.
Title: Geography of Bolivia
Content: Northernmost point – the Madeira River on the border with Brazil, near Ponte sobre o Rio Abunã, Federico Román Province, Pando Department ; Southernmost point – southern tip of the Eduardo Avaroa Andean Fauna National Reserve, Sur Lípez Province, Potosí Department ; Westernmost point – on the border with Peru, José Manuel Pando Province, La Paz Department ; Easternmost point – on the border with Brazil, Germán Busch Province, Santa Cruz Department ; Highest point – Nevado Sajama: 6,542 m ; Lowest point – Rio Paraguay: 90 m Bolivia is bordered in the northwest by Peru, and in the southwest by Chile; both Peru and Bolivia are split by the Andes Mountains roughly from north to south, and those two countries therefore have very similar geographic regions, except that Bolivia’s Pacific coast was lost to Chile during the War of the Pacific in 1880. Bolivia is also bordered by Brazil in the north and east, by Paraguay in the southeast, and by Argentina in the south.

Content:  flat. In the dry season, the lake bed can be traversed by heavy trucks. Near the Argentine border, the floor of the Altiplano rises again, creating hills and volcanoes that span the gap between the eastern and western cordilleras of the Andes. The much older Cordillera Oriental enters Bolivia on the north side of Lake Titicaca, extends southeastward to approximately 17 south latitude, then broadens and stretches south to the Argentine border. The northernmost part of the Cordillera Oriental, the Cordillera Real, is an impressive snow-capped series of granite mountains. Some of these peaks exceed 6000 m and two - Illimani  6424 m, which overlooks the 
Title: Bolívar (state)
Content:  It is bordered to the north by the Orinoco River and the States of Delta Amacuro, Monagas, Anzoátegui and Guárico; to the south by the Federative Republic of Brazil; to the southwest by the State of Amazonas; to the east by the territory of Guayana Esequiba, in dispute with the Cooperative Republic of Guyana; and to the west by the State of Apure. Three major landscapes can be recognized in a relief between the Guiana shield: the isolated Orinoco savannahs and low mountains, the mountainous landscape dominated by the tabular peaks of the Tepuis and the valleys of the tributaries of the Orinoco and the lowlands and partly savannahs of the Yuruari, limited to the east by the Imataca mountain range.

Content:  respective colors.  The Cordillera Occidental or Western Cordillera of Bolivia is part of the Andes (that is also part of the American Cordillera), a mountain range characterized by volcanic activity, making up the natural border with Chile and starting in the north with Juqhuri and ending in the south at the Licancabur volcano, which is on the southern limit of Bolivia with Chile. The border goes through the innominated point located at two-thirds of elevation of Licancabur's northeastern slope at the southwestermost point of Bolivia at 22° 49' 41" south and 67° 52' 35" west. The climate of the region is cold and inadequate for animal and plant life. Its main feature is its ground, in which are large quantities of metallic minerals including gold, silver, copper, and others. The range consists of three sections:
