Which geographic region in chile would be most difficult to develop? a) the atacama desert b) the andes mountains c) the central valleys d) the pacific coastline

A) The Atacama Desert  

Explanation: The Atacama Desert is a desert plateau situated in South America, west of the Andes Mountains. It spreads across 600-miles on the Pacific coast and is known to be one of the driest places in the world as it receives less precipitation in comparison to the polar deserts. This desert is mostly composed of salares (salt lakes), stony terrain, sand, and felsic lava which flows towards the Andes. All of these factors together make this desert the most difficult-to-develop region in Chile.  

early settlements on the subcontinent. both the indus and the ganges rivers carried rich silt from the mountains to the plains. when the rivers flooded, the silt spread over the plains and made the soil in the river valleys fertile for farming.
