Bolivia

The Altiplano is a high plateau region in west-central South America where the Andes are the widest. The bulk of the Altiplano-Puna plateau lies in Bolivia, its northern parts lie in Peru, and its southern parts lie in Chile and Argentina. The Altiplano Basin is a sedimentary basin located on the plateau.

The Amazon Rainforest is a biogeographical region in northern South America that occupies the Amazon Basin, a drainage basin of the Amazon River and its tributaries in northern South America. Sometimes called Amazônia, nine countries have some parts of the Amazon region within their borders.

Noted for its rugged and varied topography, Amboró National Park lies within three distinct ecosystems: the foothills of the Andes, the northern Chaco, and the Amazon Basin. Nowhere else in the world do three such diverse environments coincide.

The Andean Volcanic Belt, along the South American coast, is segmented into four main volcanic zones. These volcanoes, along the backbone of the Andes, are part of the Ring of Fire, an area in the Pacific Ocean basin where earthquakes and eruptions occur due to the collision of tectonic plates.

The Andes Mountains are the longest continental mountain range in the world. They form a continuous highland along the western coast of South America. The Andean Region extends north-south from Caribbean Venezuela through the Atacama Desert to cold, windy, wet Cape Horn.

One of the first protected areas to be established in Bolivia, the Beni Biosphere Reserve is located at the convergence of three biogeographical zones: the Amazon, the Chaco, and the Cerrado. The reserve is home to important indigenous Amazonian groups.

The Beni River flows north through Bolivia after rising in the Andean slopes of the Cordillera Real. The Mamoré River is formed by numerous headwaters that drain the Llanos de Moxos. The two rivers form the Madeira River on the border with Brazil.

The Beni savanna is an ecoregion located in the Beni Department of northern Bolivia. Also known as the Llanos de Moxos, it is the third-largest savanna complex in South America and is found in the lowlands of the southwestern Amazon basin, extending northeast from the foot of the Andean ranges.

The Bolivian Andes is composed primarily of two ranges or cordilleras. The Cordillera Occidental is characterized by volcanic activity. The much older Cordillera Oriental, also known as the "Cordillera Real," is an impressive snow-capped series of granite mountains.
