which two countries are on the western border of bolivia
Bolivia It is constitutionally a unitary state, divided into nine departments. Its geography varies from the peaks of the Andes in the West, to the Eastern Lowlands, situated within the Amazon Basin. It is bordered to the north and east by Brazil, to the southeast by Paraguay, to the south by Argentina, to the southwest by Chile, and to the northwest by Peru. One-third of the country is within the Andean mountain range. With 1,098,581 km2 (424,164 sq mi) of area, Bolivia is the 5th largest country in South America and the 27th largest in the world.
Backshore Sediments in this area are well-sorted and well-rounded. Its grain sizes are mainly coarse sand and medium sand, which are larger than that in littoral barrier dune.The sedimentary structures include parallel bedding and low-angle cross-bedding.
Navajo Archaeological and historical evidence suggests the Athabaskan ancestors of the Navajos and Apaches entered the Southwest around 1400 CE.[7][8] The Navajo oral tradition is said to retain references of this migration.[citation needed]
La Paz In 1898, La Paz was made the de facto seat of the national government, with Sucre remaining the nominal historical as well as judiciary capital. This change reflected the shift of the Bolivian economy away from the largely exhausted silver mines of Potosí to the exploitation of tin near Oruro, and resulting shifts in the distribution of economic and political power among various national elites.[22]
