How does the physical geography of Peru and chili influence settlement patterns in the region?

The physical geography of Peru and Chile, characterized by the Andes mountain range and coastal deserts, significantly influences settlement patterns. In Peru, settlements are often concentrated in the valleys and along the coast, where the climate is more temperate and agriculture is viable. In contrast, Chile's northern regions are arid, leading to sparse population density, while the central valleys are more densely populated due to favorable conditions for farming. Additionally, the coastal regions of both countries attract urbanization due to access to trade routes and resources, shaping their demographic distributions.
