Why is South America's population density unbalanced?

Answer 1

South America's population density is unbalanced primarily due to geographical and climatic factors. The Andes Mountains create a rugged terrain that limits settlement in the west, while the Amazon rainforest in the north poses challenges for habitation due to its dense vegetation and humid climate. Conversely, the more temperate regions in the south and along the eastern coast, particularly in countries like Brazil and Argentina, are more conducive to agriculture and urban development, attracting larger populations. Additionally, historical patterns of colonization and economic development have further influenced where populations are concentrated.
